INTRODUCTION Hi everyone, Making/Developing/Porting a Bootloader is a tedious task for newbies (even for professionals) and inexperienced hobbyists who wish to use them on their custom hardware for rapid prototyping. After searching a lot on different forums I came to a conclusion that I cant develop a bootloader just like that so my next option was porting ,that too wasnt easy if you are going with old bootloaders with limited support. I then found a very easy and efficient way of rapid software development platform that can be used on almost any IDE (Keil,Codewarrior,KDS,etc.) and can be used to develop softwares like USB MSD Bootloaders,Serial Bootloaders and other applications for almost all Freedom Development Boards ,Freescale Kinetis MCUs (on a Custom Development Board ) with minimal ARM Programming Knowledge, which is perfect for newbies like me who are just starting with ARM Development using freescale or other boards.See Welcome to the homepage of the µTasker operating system with integrated TCP/IP stack, USB and target device simulator Now my project was to make custom board using MK22DX256VLF5 (48 LQFP) MCU ,my board is a rather a simple one using basic filtering circuits for powering the MCU and almost all the pinouts given as hardware pins on the dev board.Somehow I was able to flash my first blink code using Keil IDE using the OpenSDA circuitry of FRDM-KL25Z (J-11 trace cut ) with CMSIS-DAP firmware (OpenSDA app ) loaded on to it using SWD Programming. With the steps mentioned below I'll show you how to port a Mass Storage Device (MSD) Bootloader using uTasker project from scratch. REQUIREMENTS Programmer(Hardware) or Emulated Programmer(OpenSDA apps): Segger Jlink, P&E Multilink ,OpenSDA Emulators (Jlink-SDA, CMSIS-DAP,USBDM ) IDE :Keil,Codewarrior, Kinetis Design Studio etc. (I prefer CW 10.6 ) Target MCU: Choose any MCU between Kinetis,Coldfire V2,STM32  (I am using Freescale Kinetis MK22DX256VLF5 ,48 LQFP ) refer - http://www.utasker.com/ PROCEDURE 1. Lets start by downloading the uTasker project/framwork (for Kinetis ) from µTasker Kinetis Developer's Page . Then extract and copy the folder to your CW workspace ,import the project to CodeWarrior IDE, It should look like this. (I am using version 14-9-2015)   2.Next Select "uTaskerSerialLoader_Flash" from the Five build configurations (refer http://www.utasker.com/docs/uTasker/uTaskerSerialLoader.PDF  ).uTaskerBM_Loader is described in http://www.utasker.com/docs/uTasker/uTasker_BM_Loader.pdf This is a very small loader alternative that works together with an initial application. uTaskerV1.4_BM_FLASH is the application to build so that it can be loaded to a loader (including the USB-MSD one). uTaskerV1.4 is a 'stand-alone' version of the application that doesn't work together with a loader (and doesn't need a loader).If you want to build application to load using the USB-MSD loader you need to use uTaskerV1.4_BM_FLASH. after that find the files config.h and ap_hw_kinetis.h.These files define the type of MCU you use. 3.In config.h Select your board or MCU type or the closest MCU resembling the architecture of your own MCU. My MCU  MK22DX256VLF5 was not there so with a little help from mjbcswitzerland  I chose TWR_K21D50M Board settings as TWR-K21D50M module is a development board for the Freescale Kinetis K11, K12, K21 and K22 MCUs. (Note : Be sure to remove or comment any other defined boards ) After Selecting the Board/MCU scroll down to find USB_INTERFACE and USB_MSD_LOADER and make sure that these two are defined (not commented ).This is necessary to enable USB enumeration as Mass storage device. Also comment the following if already defined : HID_LOADER KBOOT_HID_LOADER USB_MSD_HOST This is necessary as we are using our Bootloader in MSD Device Mode not in MSD Host Mode. Also we arent using HID_LOADER and KBOOT. Now open  ap_hw_kinetis.h and Find your selected MCU (in my case its TWR_K21D50M ) So, Find the String "TWR_K21D50M" (or whatever your MCU is ) and see if the follwing lines are defined. #define OSC_LOW_GAIN_MODE #define CRYSTAL_FREQUENCY    8000000  #define _EXTERNAL_CLOCK      CRYSTAL_FREQUENCY #define CLOCK_DIV            4                                      or    #if(..........)         #define CLOCK_MUL        48                                            #define SYSTEM_CLOCK_DIVIDE 2                                      #else         #define CLOCK_MUL        24 #endif     #define USB_CLOCK_GENERATED_INTERNALLY Here comes an integral part of USB MSD Bootloading/Programming.You must be wondering about CRYSTAL_FREQUENCY  8000000 and  CLOCK_DIV   4  .This is the frequency of an external crystal oscillator  (8mhz) connected between EXTAL0 and XTAL0 pins of the Target MCU.If your MCU has an internal oscillator then check whether the latter is defined. refer- https://cache.freescale.com/files/microcontrollers/doc/app_note/AN4905.pdf          http://www.utasker.com/kinetis/MCG.html There are two ways to be able to use USB: 1. Use a crystal between EXTAL0 and XTAL0 - usually 8MHz is used. (with or without load capacitor -both worked for me ) 2. Use a 48MHz oscillator on the USB-CLKIN pin. First one is easier and it worked for me.Since my MCU doesnt have an internal oscillator I have used and External 8Mhz crystal. If you want to use a 16Mhz crystal then just make the following changes : #define CRYSTAL_FREQUENCY    8000000 #define _EXTERNAL_CLOCK      CRYSTAL_FREQUENCY #define CLOCK_DIV            4                                 TO #define CRYSTAL_FREQUENCY    16000000 #define _EXTERNAL_CLOCK      CRYSTAL_FREQUENCY #define CLOCK_DIV            8 Note: The CLOCK_DIV should be such that it prescales the crystal frequency to range of 2-4MHz. Here is the clocking diagram of My MCU.The next diagram shows an oscillator crystal connected externally to my dev board. Next search for "PIN_COUNT" under your corresponding MCU/Board (mine is TWR_K21D50M).My MCU is 48 LQFP with 256kb flash and 32kb SRAM (you have to change them according to your MCU ).So I have changed the following lines                              from   #define PIN_COUNT           PIN_COUNT_121_PIN                         #define SIZE_OF_FLASH       (512 * 1024)                          #define SIZE_OF_RAM          (64 * 1024)                              to   #define PIN_COUNT           PIN_COUNT_48_PIN                      #define SIZE_OF_FLASH       (256 * 1024)                              #define SIZE_OF_RAM          (32 * 1024)  Next if you search for your MCU/Board (in this case TWR_K21D50M) ,you will find this line : #define UART2_ON_E This defines the alternative port for UART2,since many boards doesnt have PORTE ,it can be chaned to other ports. [its not important though] Note : When building the serial loader for a device with small RAM size reduce the define #define TX_BUFFER_SIZE (5512) to 512 bytes so the buffer can be allocated (the large size was used only for some debugging output on a larger device) [loader version :14.9.2015] Now search for the String "BLINK_LED" under your corresponding MCU/Board ( mine is TWR_K21D50M ) .The uTasker Bootloader has a special function ,whenever it is in MSD/LOADER mode it blinks a test LED on the board.This is not important but it can be used for debugging purposes.I have a test LED on my board at PORTB16 .You can also specify hardare pins to force bootloader mode and to stop watchdog timer if you pull SWITCH_3 and SWITCH_2 down to ground respectively.I am setting SWITCH_3 and SWITCH_2 as PORTD7 and PORTD6 respectively. Now on the toolbars go to Project > Properties > C/C++ Build > Settings > Tool Settings > Target Processor :Change it to your MCU type (mine is cortex-m4 ) .Next go to Linker >General and change the linker script file to match your MCU's flash,RAM,Type.I have set mine to K_256_32.ld (Kinetis K type processor with 256kb flash and 32 kb RAM) Apply your changes.Now you are ready to go. 4.  Build your project under SerialLoader_FLASH configuration .If there are no compilation errors then you have done it! (if there are then recheck everything with this guide ) Now Click the Flash programmer icon a and Select Flash File to Target. (if your not getting the icon switch to "DEBUG" perspective view ) Now you may choose your Programmer (or emulated programmer )[connection tab] ,select the correct Flash configuration file ,then browse for the binary file that has been generated under C:\Users\<computer user>\workspace\Kinetis_14-9-2015\Applications\uTaskerSerialBoot\KinetisCodeWarrior\uTaskerSerialBoot_FLASH\uTaskerSerialBoot.bin and Click on "Erase and Program". You may skip Step 5 and go to Step 6. 5.I am using the OpenSDA circuitry of my FRDM-KL25Z (J-11 trace cut ) as a programmer using J-link OpenSDA app. Download the app from SEGGER - The Embedded Experts for RTOS and Middleware, Debug Probes and Production Programmers - OpenSDA / OpenSDA V2 depending on your OpenSDA version (FRDM KL25Z has OpenSDAv1). Refer - Using the Freedom Board as SWD Programmer | MCU on Eclipse 5.1.First Enter bootloader mode and Flash the Jlink sda app into it.Connect the SWD wires from the board to your  Target MCU/Board ,also connect the target board        to the external oscillator.Also connect the FRDM's OpenSDA through USB. (A drive with the name JLINK Should come )                                          5.2. Go to Flash File to target and under connections tab click new. give any name and click new under Target Tab.Then select the target type (your target MCU ,mine is                      K22DX256M5).Then check Execute Reset under Initialization Tab. Click finish.    Now you'll get the option to select connection type ,then choose J-Link/J-Trace for ARM and change the Debug port interface to SWD .If you get the error :connection name is not        unique then just change the name (I have used jlink1).Click Finish.     Now I have set up my connections so I can flash the MCU with Jlink app on my OpenSDA circuitry. 6. Now to verify USB Enumeration of your Custom Board ,connect it to PC using USB and you should get a drive with the name UPLOAD_DISK.

Summary: This page contains the technical information for the FRDM-JAM shield.    This includes the Schematics, Bill of Materials (BOM),  Gerber Files and raw design files. See the attachments section.   There are 2 versions long this page.  Rev Gamma and Rev Delta. Rev Gamma:      This was the version for designed around the K20D50 FRDM board.   At the time of the design,  the FRDM-K64F did not exsist Rev Delta This version added IO connections to be able to use the FRDM-K64F.    The FRDM-K64F uses a different I2S pinout so a jumper had to be added as well as the QSPI RAM devices in Gamma had to be remove Other Special Notes about Rev Delta Rev Delta was design such that a FRDM-K64 could be used.      There is not yet firmware available but the hardware now allows connection to the K64F I2S interface. Rev Delta requires that J16 must be cut on the FRDM-K20D50 PCB.  There is a trace connecting the pads of J16 on the bottom side of the FRDM-K20D50.      This cut allows the audio transmit frame sync to work properly.   The signal INT2_ACCEL on the FRDM-K20D50 was interfering with the signal on the FRDM-JAM Rev Delta Introduced an I/O mapping bug.  IO Epsilon connects to PTC9 of the K20D50.     This also maps to the I2S RXD if using with the K64F and is also routed to PTC5 of the K20D50.     Do not use IO epsilon in your code unless you make the proper PCB modifications. Example software, video tutorials tutorials, cool demos, etc are location on the page for MonkeyJam project located here. MBED Support coming *very soon* Notes: You can order PCBs through OSHPark or your favorite board house.   There is a special .zip file with files ready to go for OSHPark (using their preferred naming convention). There is a complete design package which has the raw design files (Altium Designer Format) as well as gerbers,  a Bill of materials,  assembly plots etc.  Look in the "BUILD_PACKAGE" folder for the stuff needed to make the board. A PDF Schematic is also provided for easy reference. If you are interested in a low cost pre-fabbed board or a fully assembled version,  please leave a comment.  A kickstarter project may follow to get a bunch built!

A microcontroller includes a microprocessor (CPU) as well as a number of other components like RAM, flash and EEPROM to store your programs and constants. While a microprocessor requires external devices to control things like input/output, or timers to implement periodic tasks, and digital to analog converters, a microcontroller is all inclusive. Contrast this all-in-one approach with a typical personal computer which contains an INTEL or AMD CPU, as well as separate chips for RAM, a separate video card, a dedicated hard drive, silicon chips or PCI circuit boards to enable the processor to access USB, serial and video card signals Microcontroller pins are general purpose, whereas CPU pins are specific. This means that each pin is tied to a multiplexer which you must set to choose the particular use for the pin. For example, in a microcontroller, one pin pin might be re-purposed for the following tasks 1. The output of a timer 2. Send a signal to a motor 3. Receive an input from a sensor or analog device Basic Concepts Covered Thus far: Blink an LED - overview of GPIO and setting up the microcontroller Drive a Motor - using the Timer and PWM modules of the microcontroller Turn a Servo - More details on using timer modules and PWM to control a servo Obtain Data from the Line Scan Camera - ADC Setup and GPIO Bit Blasting to create clock and pulse signals controlling the line scan camera I2C tutorial - Using I 2 C to communicate with various sensors using the K40 Button - An overview of how to implement a simple button Additional Concepts we would like to add to the Wiki: Timer Modules PWM watchdog-timer memory

In this training video we will decompose an NTSC video signal to gaining understanding of how to capture video data from a "analog" camera.

How to install a servo horn.  More specifically for the Freescale Cup kit. [no audio]

In this video we will look at the example code provided for the FRDM-TFC for use with Codewarrior.  

Instructions There are several main hardware configuration steps. Once the USB cable has been connected between the evaluation board and PC, it may be necessary to update the chip firmware which requires moving a jumper pin on the evaluation board. Then, connect one end of the USB cable to the PC and the other end to the Power/OSJTAG mini-B connector on the TWRK60N512 module. Allow the PC to automatically configure the USB drivers if needed. Before updating the firmware, it is necessary to start a CodeWarrior Project. In this case, the easiest way to do this is to actually navigate to the sample project and click on the Sample.mcp file. This will open CodeWarior 2.8. Selection Project->Build Configurations->MK40X256VMD100_INTERNAL_FLASH Project-»Build All Run->Debug Configurations—> Use the Codewarrior download Filter and Select "PROJECTNAME_MK40XD256VMD100_INTERNAL_FLASH_PnE_OSJTAG" Additional step is required if the firmware is out of date: Firmware Upgrade Instructions (if needed)   Firmware may change after an evaluation board has been manufactured and shipped. As a result, an alert will be displayed during the first attempt to download software to the board. Follow the instructions carefully. 1.     Unplug the USB cable.   2.     Look for the jumper (On the REV B Board) labeled "OSBDM_IRQ" - it is jumper 35. It will be found between the on/off switch and to the right of the the white "Lin" connectors. Remove one of the "LED Enable" jumpers for this if you don't have a   header jumper handy and put the jumper on the OSBDM_IRQ header These LED Jumpers are just above the blue potentiometer knob and marked as "J27."   3.    Reconnect the USB cable and click OK.   4.     Wait for the new firmware to download. 5.     A new dialog will appear when the process is complete.  6.    Unplug the cable, remove the jumper, return it to the location it was "borrowed from" and reconnect the cable. 7.    Then click OK.

This video will examine how can design speed sensing into their vehicle platform.   An example of magnet and sensor placement is shown.
