generating a .a00 file

Hello everyone,

I have already posted about this in another thread but got no answer, so I try to post it in a new thread.

I want to use a C28346 and as this delfino has no internal flash, I want to use the serial eeprom on the ControlCard to store the my program.I have read the forums and litterature carefully and understood that I have to first generate a .a00 file that I will put in my eeprom. According what i have read, this file must be generated through the hex2000.exe. I am using the post-build command method. the command line I use is:

hex2000 -i DSP_MF.out -a -o DSP_MF.a00 -boot -i2c8 -i2cpsc=0x1D -i2cclkh=0x05 -i2cclkl=0x0A

I have no compilation error but no .a00 file is generated and i get the following message in the console:

C:/ti/ccsv5/utils/bin/gmake --no-print-directory post-build
hex2000 -i DSP_MF.out -a -o DSP_MF.a00 -boot -i2c8 -i2cpsc=0x1D -i2cclkh=0x05 -i2cclkl=0x0A
make (e=-1): Error -1
gmake[1]: [post-build] Error -1 (ignored)

Could someone help me? I have already worked a lot on this problem ans the remaining time allowed to me for this development is running short :(

Thanks a lot in advance!

Christian

    Christian,

    It may be that CCS is not finding the path to hex2000. Instead of hex2000 you can specify the build variable ${CG_TOOL_HEX} which automatically resolves the path information to the hex2000 within the compiler tools directory.

    So, for example, try setting your post-build step in CCS to look something like this:

    ${CG_TOOL_HEX} -i DSP_MF.out -a -o DSP_MF.a00 -boot -i2c8 -i2cpsc=0x1D -i2cclkh=0x05 -i2cclkl=0x0A

    Let us know if that works.

    If it still fails, another quick test is to verify that the command works fine when run from a Command Prompt instead of within CCS. Simply open a command prompt, and enter the command as you have shown above but be sure to include full paths to hex2000, DSP_MF.out etc.  hex2000 will be in the \bin folder within the compiler tools directory.

    Thanks AartiG, that works! You were right, the problem was about finding the path to hexe2000. Indeed, the following command that specifies the path produce the same result.

    "C:\ti\ccsv5\tools\compiler\c2000_6.1.0\bin\hex2000.exe" -i DSP_MF.out -a -o DSP_MF.a00 -boot -i2c8 -i2cpsc=0x1D -i2cclkh=0x05 -i2cclkl=0x0A

    Nevertheless, i still have a small question: when i open my file with the wordpad, my first line looks like this.

    :20000000AA ....

    while the final line ends like that.

    ... 00001FF

    But according of what I read in TMS320C28x Assembly Language Tools v6.1 (SPRU513E), page 283, my file should look like:
    ^B $AXXXXXXXX,
    XX XX XX XX XX XX XX XX XX XX. . .^C
    Is that a problem? Did i choose the wrong option?
    Thanks agina for your help,
    Christian

    You have both the -i (intel hex format) and -a (ascii format) options in the command line. Remove the -i option and keep only the -a option.

    That's a stupid mistake! Thanks even more for your help.

    I don't know where that come from.

    now my .a00 file looks exactly like it should :)
