Compiler/TMS320F28386D: CM Flash API program fail

Tool/software: TI C/C++ Compiler

Hi,

I used armhex.exe to convert cm.out to b0 with below command. (from C:\ti\ccs930\ccs\tools\compiler\ti-cgt-arm_18.12.6.LTS\bin)

..\%TOOLDIR%\armhex.exe cm.out -boot -gpio8 -b

Then interpret the .b0 file and program data by cm flash api.

Some address can program as expected, but some fail.

for example,

Success address:

Fail address: 0x208AE8

When it was fail, I have checked below:

1. Arguments of address, buffer data in Fapi_issueProgrammingCommand() are all correct.

2. After Fapi_checkFsmForReady() was ready, Fapi_getFsmStatus() returned zero. Its mean there was no error.

3. Fapi_doVerify() return Fapi_Error_Fail, the compared date is correct but value in memory all 0xFFFF

Is the address 0x208AE8 not match 128-bits alignment?

However I have added align(8) in my .cmd file.

Frederick,

Please align the sections in linker cmd for align(16). For arm core, 128-bit alignment is achieved by using align(16). This is mentioned in FAQ here e2e.ti.com/.../951658.

0x208AE8 is not 128-bit aligned. It is 64-bit aligned. Hence, when calling program function for this address, you can program a max of 64-bits (8 bytes). Maybe you are trying to program more than that (128 bits)? Please check.

When it failed, program function would have returned an error - did you check the return value from the program function? If not, please check.

If above does not help to resolve the issue, please provide the snapshot of the code where you call the program function, Fapi_checkFsmForReady(), Fapi_getFsmStatus() and Fapi_doVerify().

Thanks and regards,
Vamsi

Hi Vamsi,

After I modify cm.cmd to align(16), I can burn in my codes successfully with no error.

I call Api functions just like C2000Ware example flashapi_cm_ex1_programming.c in version 3.2.0.

I see "TMS320F2838x Flash API Version 1.60.00.00 Reference Guide", it means that all 3.x.x C2000Ware FlashApi examples should match 128-bits alignment.

Is the key point buffer size 16?

Fapi_issueProgrammingCommand((uint32 *)u32Index, Buffer+i,16, 0, 0, Fapi_AutoEccGeneration);

Does it mean that If modified to buffer size 8, can program the address align 64-bits?

Fapi_issueProgrammingCommand((uint32 *)u32Index, Buffer+i,8, 0, 0, Fapi_AutoEccGeneration);

Thanks and regards,

Frederick

Frederick,

Glad it helped.

Yes, if the address that you pass for program function is 128-bit aligned, then you can program 16bytes.

You can program 8 bytes by providing a 64-bit aligned address.

Thanks and regards,
Vamsi

Vamsi,

I have understood and solved my problem.

Thank you for your help.
