What compiler/tool chain?

What programming tools do you want to use? There are multiple ways of achieving this kind of thing. You could for example use XMODEM to download the file if you implement an update internal hex image function within your application code. (I've done this, and pulled from HTTP servers with wireless modems) You could hard code it within an include file. You could make a simple app to generate such code. char myHexImage[] = '':0200000423F0E7\n'' '':1000000018F09FE518F09FE518F09FE518F09FE5C0\n'' '':1000100018F09FE50080000020FF1FE520FF1FE58E\n'' '':100020005800F0234000F0234400F0234800F02360\n'' '':100030004C00F023000000005000F0235400F02397\n'' .. '':04117000000000007B\n'' '':0400000523F000AC38\n'' '':00000001FF\n''; You could also store the data in binary, and output Intel or Motorola hex on the fly. Tools like J-FLASH, ST-LINK, and the ST Flash Loader, should all permit writing to arbitary addresses. You could merge your file on the end of you application binary. Insert it into an ELF file. Generate a hex file from the hex file, and merge it with the hex file from your application. The scatter file method might also work, depends on the tools, should be able to Google the syntax. http://www.keil.com/forum/18585/ http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.kui0100a/armasm_caccaghf.htm http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.faqs/ka3700.html

Clive, thank you so much. I am really impressed !

sorry, I forgot to mention the toolchain - it's Keil MDK-ARM. the are few details related to my project. - The controller i am using (STM32F103) is by itself programmed by another controller through the serial port, so programming tools wouldn't work. - from my controller I need to program the NXP P89LPC922, and it accepts only Intel hex format in IAP mode. - I am using a scatter file to add some metadata at the end of a code memory, so merging will complicate things So it seems like in my case 2 methods are appropriate: - using of an include file - creation an assembler file and importing my hex file using INCBIN Second method may be easier since it wouln't require an additional application to generate the proper array. I used IAR with avr controllers before, and it had a special provision for such inclusion. It made things easier. Thanks a lot again
