I’m using the NXP FRDM-K64F board in several projects.One issue I have faced several times is that the board works fine while debugging and connected and powered by a host machine, but does not startup sometimes if powered by a battery or started without a debugger attached. I have found that the EzPort on the microcontroller is causing startup issues. The EzPort is a special serial interface present on some Kinetis, ColdFire+ and ColdFire V2 devices. The issue is that if the EzPort chip select (EZP_CS) is LOW during reset of the microcontroller, it enters the special EzPort mode. The problem is that a pull-up on the EZP_CS line might not pulled up fast enough due capacitance on the line. The commance is if something is not used, disable it! So the solution is to disable the EzPort functionality. That setting is part of the FOPT (flash option register).

As general introduction on thread https://community.freescale.com/docs/DOC-328302 , I did a smart LED application with GoKit and FRDM-KL02. In this design, FRDM-KL02 will communicate with GoKit by WIFI, and control LED flash. Code Structure Code Basic Introduction In this project structure, you need to do following items on code. ü Add your functions, such as UART, LED, motor driver code. ü Add function running functions in protocol.c ü Add functions order in main loop. You can find my main.c and protocol.c as attachment. In this document, I would like to detail introduce function MessageHandle()， void MessageHandle(void) {                 pro_headPart    tmp_headPart; //Common command package                 memset(&tmp_headPart, 0, sizeof(pro_headPart));                 if(get_one_package)                 {                                                                              get_one_package = 0;                                 memcpy(&tmp_headPart, uart_buf, sizeof(pro_headPart));                                                                 //CRC error, send back error command                                 if(CheckSum(uart_buf, uart_Count) != uart_buf[uart_Count-1])                                 {                                                 SendErrorCmd(ERROR_CHECKSUM, tmp_headPart.sn);                                                 return ;                                 }                                 So, you can see that only get_one_package=1, we can receive frame completely.                                 switch(tmp_headPart.cmd)                                 {                                                              case       CMD_GET_MCU_INFO:                                                                 CmdGetMcuInfo(tmp_headPart.sn);                                                                                                                                     break;                                                                   case CMD_SEND_HEARTBEAT:                                                                 SendCommonCmd(CMD_SEND_HEARTBEAT_ACK, tmp_headPart.sn);                                                                                 break;                                                 case CMD_REBOOT_MCU:                                                                 SendCommonCmd(CMD_REBOOT_MCU_ACK, tmp_headPart.sn);                                                 case       CMD_SEND_MCU_P0:                                                                 CmdSendMcuP0(uart_buf);                                                                 break;                                                 case       CMD_REPORT_MODULE_STATUS:                                                                 CmdReportModuleStatus(uart_buf);                                                                 break;                                                 default:                                                                 SendErrorCmd(ERROR_CMD, tmp_headPart.sn);                                                                 break;                                 }                              } } After that, you can do operations mentioned in thread https://community.freescale.com/docs/DOC-328302. You can see smart LED device and been found.

The mbed Compiler delivers full online editor. it provides a lightweight online C/C++ IDE that is pre-configured to let you quickly write programs, compile and download them to run on your mbed Microcontroller. The only weakness is that it doesn’t have debug feature. In fact, you don't have to install or set up anything to get running with mbed. Because it is a web app, you can log in from anywhere and carry on where you left off, and you are free to work on Windows, Mac, iOS, Android, Linux, or all of them. Currently, mbed Compiler support: FRDM-KL25Z FRDM-KL46Z FRDM-KL05Z FRDM-K20D50M FRDM-K22F Ethernet IoT Starter Kit This article will introduce how to use mbed Compiler to develop code on Freescale FRDM board. Summary:  we can use mbed Online Compiler edit, build, generate binary file. But CAN’T debug. With mbed FRDM KL25z Upgrade pakage, we can burn binary file to board with drag and drop. Its really simple, and it's free, because it is a web based compiler, multi-platforms are supported. so lets get started!

Este proyecto está siendo desarrollado por alumnos del Tecnológico de Monterrey Campus Guadalajara, el cual está orientado para servir como un tipo de terapia para personas discapacitadas. El proyecto en sí consiste en el control de un vehículo de juguete por medio de pulsaciones que serán realizadas con pelotas anti-estrés, de esta forma la persona podrá realizar un ejercicio de fortalecimiento en sus extremidades superiores de una forma más entretenida y menos tediosa que las clásicas terapias. Es importante mencionar que para poder realizar este proyecto es necesario el uso de dos tarjetas Freedom KL25Z de Freescale®, dos módulos Bluetooth®, dos servomotores de rotación continua y dos sensores de presión, los cuales serán incorporados dentro de las pelotas anti-estrés. El vehículo de juguete estará compuesto por los servomotores, que servirán como llantas; un módulo Bluetooth®, el cual recibirá las señales del otro módulo; y una de las tarjetas Freedom KL25Z. Por otro lado una de las tarjetas Freedom KL25Z estará conectada con los sensores integrados en las pelotas anti-estrés y a un módulo cuya función es mandar la información capturada por los sensores al vehículo de juguete. La mecánica del proyecto depende de la pelota que sea presionada, pues si se presiona solamente una pelota, el vehículo avanzará, por otro lado si se presiona la otra pelota, el vehículo girará sobre su propio eje. Este proyecto tiene como fin la implementación de conocimiento prácticos y teóricos en busca de una aportación en beneficio de la sociedad. También es relevante comentar que las visiones a futuro de este proyecto es que pueda ser implementado como una especie de control para una silla de ruedas, con el fin de facilitar la movilidad y aumentar la comodidad al momento de usar este tipo de vehículo.

This project is for neck's physical therapy and for a wheel chair that will move just with two buttons. This project is intended to be for persons who cannot move arms to do stuff.Instead of having a little joystick to move, they will just have to press one button turn around on the wheel chair or press the other button to make it advance. Because of the time we have to present this project, we will for now apply this idea to a toy car that will help children to do physical therapy on the neck.   Silla de Ruedas controlada por movimientos del cuello - YouTube   Facebook Original Attachment has been moved to: Code.zip

近期有客户提出需求，要求通过外部Flash编程工具烧写Flash Program Flash IFR区域。 目前P&E Cyclone MAX和Segger J-Flash均无法实现对IFR区域编程。 客户可以使用软件的方式来编程IFR提供的单次烧写区域，存储客户产品信息，例如MAC地址等。 Program Flash单次烧写区域提供了64个字节，只允许烧写一次，通过Program Once和Read Once命令来读写这个区域。 下图为单次烧写区域在Prgoram Flash IFR的具体位置， IFR独立于FTFL Flash空间，可以理解成另外一个Flash模块。 Program Once和Read Once命令每次调用可以读取Program Flash单次烧写区域的4个字节，通过命令参数的数据索引号可以通过多次操作遍历整个64个字节。 附件中的例程使用Program Once命令编写MAC地址到单次烧写区域，之后通过Read Once命令读取MAC地址信息。 例程环境： IAR Workbench + TWR-K60D100M

Recently I have received a report which said the customers met compiling issue when they imported the an2295sw CW project file and started to build it, the error message is like the following: When I looked into this issue, I found it was mainly due to some asm source file which was dedicated for Keil wrongly included in the CW project , so there would syntax error during compiling, and the linker issue was due to the path of linker file was wrongly defined, fix them would solve most of the compiling. 1. Fix source file issue: deselect the bootloader.asm file. 2. Fix linker file issue: redefine the correct path for linker file There is also an exception when you try to compile with the configuration for K70 120MHz part, it is due to some files can not be opened because the including path are missing: so besides the above changes, you have to add the paths below to solve this issue for Kinetis 120MHz part.    BTW, during debugging, I also found it is not convenient to switch between different configurations because users have to choose the proper header file for different platforms manually, so I add the following changes to support automatic switching platform according to the configuration but just with an exception for Kinetis K-1M 100MHz part, which still have to choose the proper platform manually. Customers who have downloaded an2295sw may directly replace the following files with that I attached in this document, which have included all above changes mentioned. an2295sw\src\Kinetis\CW_10.3\AN2295_Kinetis\.project an2295sw\src\Kinetis\CW_10.3\AN2295_Kinetis\.cproject an2295sw\src\Kinetis\CommonSource\bootloader_cfg.h Hope that helps, Kan
