CCS v6 hex utility

Vaman Bvr
Prodigy 160 points

I am trying to use CCS v6 built-in hex utility to generate hex output file. Looks like the output hex file contains half of the text section (If I dump the hex file it shows text section from 20007C to 207BD8.). Why the hex file does not show text section from 21xxxx ? I am using F28M35HC1 which has 512K flash. Using C2prog (via UART0) I can program the flash, but after reset, system does not start. I suspect only half of flash is programmed.

I used hex2000 and RTOS-Oct27.out to generate hex output file. This also looks exactly same.

Any idea what is wrong ? 

Here are relevant sections of linker, map and hex files.

    The hex converter is clearly trying to initialize addresses 0x217c10, etc.   The second-to-last line of the hex output you posted shows a write of 10 bytes to address ??7C10.

    len addr tp ck bytes                          ck
:10 7C10 00 00 0C0001767400216000200000400000 8C

    Remember that the Intel format can only hold 16 bits worth of the address.  The upper 16 bits of the address are specified in an extended address record, of type "04".  Are you absolutely sure there isn't a preceding "04" record for 0021?  It would look like this:

    len addr tp ck
:00 0021 04 FF

    You mention hex2000 and C2prog, however the executable seems to be for the ARM processor as ARM hex utlity armhex is being run on it. If this is indeed an ARM executable, could you try setting the romwidth and memwidth to 32 and see if that helps?

    Thanks. 0x217c10 is there in the hex output file. It was in the middle part of the file (see the contents at the end of this message). So it looks like the content of the file is right - but something else is not right.

    I use CCS jtag to program flash first and make sure it works and then use c2prog (uart0 interface) to overwite the content of the flash just to test.  C2prog erases JKLMN (Smart sector selection) and programs without any problem. But after I change SW1 to boot from flash, it does not run. I tried both  (romwidth=16 and memwidth=16) and (romwidth=32 and memwidth=32) on M3 (F28M35xx) - no success.  

    I tried to program only JKLM sectors by removing the contents of N from hex file and manually erasing JKLM sectors. But c2prog ends up with write error on sector J (write wrror 509 : address 0x21xxxx) though it erases that sector.

    You should consider using a hex command file if you want to pick and choose sections to program.  If you cut up the hex file by hand, you risk inadvertently cutting out an "04" record or similar.

    I'm sorry, I'm not at all familiar with c2prog, so I can't help you with that specifically.
