[COLOR=#000000][FONT=Times New Roman, serif][SIZE=4]Dear Friends,[/SIZE][/FONT][/COLOR]

[COLOR=#000000][FONT=Times New Roman, serif][SIZE=4]I am working on LPC 1769 Controller. I am trying to implement [B]boot loader[/B] in my application so that I can update the firmware in the target board MCU through network (I need to download the firmware to MCU without JTAG, through network).[/SIZE][/FONT][/COLOR]

[COLOR=#000000][FONT=Times New Roman, serif][SIZE=4]If anybody having standard code and suitable documents for this, Plz give me. [/SIZE][/FONT][/COLOR]

[COLOR=#000000][FONT=Times New Roman, serif][SIZE=4]And suggest me how to begin this application. [/SIZE][/FONT][/COLOR]

Checkout Flash Magic, download and install from Flash Magic.com.
It has secondary Bootloader support for the LPC2000 and LPC1700 family
See C:\Program Files (x86)\Flash Magic\Ethernet Bootloader\LPC1700

[FONT=Times New Roman, serif]Thanks for your reply,[/FONT]

[FONT=Times New Roman, serif]I gone through that www.flashmagictool.comwebsite and got some documents. I am reading those documents now.[/FONT]

[FONT=Times New Roman, serif]My application is to download firmware from Computer (PC) to LPC1769 Controller in both wired and wireless connection. So I need your help for this. [/FONT]

[FONT=Times New Roman, serif]I think you also proved boot loader, If possible may I know your application.[/FONT]

Code Red provide some bootloader examples in the LPCXpresso bundle.

Take a look at the LPC17xx/RDB1768_cmsis2.zip pack of examples, and look at RDB1768cmsis2_usb_bootloader project. LPC1768 and LPC1769 are identical apart from the max speed of the clock.

They provide some notes in the project, and there is also an overview here:

Another user contributed an ethernet variant of the boot loader that you may find of use here:

[FONT=Verdana, serif]This example (Standard example in C drive) bootloader is to boot through [/FONT][FONT=Verdana, serif][B]USB[/B][/FONT][FONT=Verdana, serif] but my application is to boot through Ethernet. Any suggestion for this??? And this code is to test with [/FONT][FONT=Verdana, serif][B]LPC1768[/B][/FONT][FONT=Verdana, serif] board but I am having [/FONT][FONT=Verdana, serif][B]LPC1769[/B][/FONT][FONT=Verdana, serif] Board.

[FONT=Verdana, serif]-----[/FONT]
[FONT=Verdana, serif]If I run Jharwood code, I am getting error, is this problem related to software version or any other thing. (I am using LPCXpresso v4.0.6_152). Plz anyone execute this code and let me know the solution[/FONT]

So what's the question?

After downloading bootloader it's working via USB. RDB board has a mini-B connector, which connector did you connect to your board?

I still don't understand the problem :eek:

Of course you have to delete:

#1 include and library path of LCD-Library in project properties

#2 all function calls of LCD-Library

if you don't use RDB Base Board or something else with LCD, but after that this bootloader is starting as described in its readme.txt :)

All that's working without problems here[/COLOR][/B] :rolleyes:

[FONT=Verdana, serif]In that they given as [/FONT][FONT=Verdana, serif][B]“by selecting the Debug option within IDE”, [/B][/FONT][FONT=Verdana, serif]so for this any setting changes are required in IED or just build, debug and download to lpc1769 board that’s it???[/FONT]

Of course that means a Debug Build and flashing to mcu :)

Come on, what do you think is this code doing :confused:

...
check_isp_entry_pin();
...
/*
 *[SIZE=5][B][COLOR=Red] CodeRed - joystick button is P0_6.[/COLOR][/B][/SIZE]
 */
#define ISP_ENTRY_GPIO_REG 0x2009C014  /* Port */
#define ISP_ENTRY_PIN        6          /* Pin  */
...
void[COLOR=Red] check_isp_entry_pi[/COLOR]n(void)
{
    if( (*(volatile unsigned *)ISP_ENTRY_GPIO_REG) & (0x1<<ISP_ENTRY_PIN) )
    {
        // Display message to RDB1768 LCD
//        LCD_PrintString2Terminal ("Button not\npressed.\n", LCD_TERMINAL_NoNL,COLOR_BLUE, COLOR_YELLOW);

        execute_user_code();
    }
    else
    {
        // Enter ISP mode

        // Display message to RDB1768 LCD

[COLOR=#000000][FONT=Verdana, serif]Hi Zero, Very good morning.[/FONT][/COLOR]

[COLOR=#000000][FONT=Verdana, serif]I gone through RDB1768 board schematic and understood JOYSTICK connection. Default value on P0.6 is HIGH and after pressing JOYSTICK, P0.6 will become LOW.[/FONT][/COLOR]

[COLOR=#000000][FONT=Verdana, serif]I tested by making HIGH & LOW on P0.6, but result is nothing for me.[/FONT][/COLOR]

[COLOR=#000000][FONT=Verdana, serif]Sorry to Say that I am little bit weak in C coding (Still here I was working on MATLAB & VERILOG). I didn’t understood following line[/FONT][/COLOR]

if( (*(volatile unsigned *)ISP_ENTRY_GPIO_REG) & (0x1<<ISP_ENTRY_PIN) )

is reading bit 6 of Port0 to check if you want to start bootloader :eek:

If you comment out execute_user_code() you can force the code to start bootloader :rolleyes:

If nothing happens then you have failed to install a working USB connector to your LPC1769 or your PC isn't working correct

   if( (*(volatile unsigned *)ISP_ENTRY_GPIO_REG) & (0x1<<ISP_ENTRY_PIN) )
    {
        // Display message to RDB1768 LCD

Hi Hareesha, just curious... are you connecting the USB cable to the same connector that you used for programming the LPC1769 board?

Second question, are you using the RDB1769 shown in image below? Because from one of your earlier emails I think you are using the LPCXpresso board from Embedded Artists.

---> Yes.

[COLOR=#000000][FONT=Verdana, serif]Hi zero, [/FONT][/COLOR]

[COLOR=#000000][FONT=Verdana, serif]As you told like now my LPCEXPRESSO board is detecting as USB mass storage device. I download boot loader code, terminated, disconnected and connected again to PC through same usb cable then it asked driver for that, so I installed form the path “C:\nxp\LPCXpresso_4.0.6_152\Drivers\DFU”. But still I am not seeing that drive in” mycomputer “.[/FONT][/COLOR]

[COLOR=#000000][FONT=Verdana, serif]But now I am not able to download new code to my board. IF I try to debug code it is showing linker error (As like show in attached image). [/FONT][/COLOR]

[COLOR=#000000][COLOR=#ff0000][FONT=Verdana, serif][B]Note[/B][/FONT][/COLOR][FONT=Verdana, serif]: In LPCEXPRESSO board I am having only one USB connector for downloading code and for use as USB device. But I think in RDB1768 board these are separate??? [/FONT][/COLOR]
