TMS320F28386S: Illegal operation with library flash command.

John Hite

Part Number: TMS320F28386S
Other Parts Discussed in Thread: C2000WARE

In copyData() in this file:

C:\ti\c2000\C2000Ware_4_01_00_00\driverlib\f2838x\examples\c28x_dual\flash_kernel\flash_kernel_c28x_dual_ex1_boot_cpu1.c

My program crashes with an illegal operation on the 2nd call to

oReturnCheck = Fapi_doBlankCheck((uint32_t *)sectorAddress,
sectorSize,
&oFlashStatusWord);

Debug trace says

Intterupt_illegalOperationHandler() at interrrupt:158 0x0874A0

This is a library function with no source so I cannot debug it.

Hi John,

Is this function placed in flash or RAM?

Can you check whether or not the contents of the function are intact in the memory where it is placed?

Thanks and regards,

Vamsi

Thanks for the idea Vamsi, you were right. The pragma preamble for the function did not match the section name in the linker file. I fixed that and now have exposed a new problem. The error is:

"../2838x_flash_lnk_cpu1.cmd", line 67: error #10099-D: program will not fit into available memory, or the section contains a call site that requires a trampoline that can't be generated for this section. run placement with alignment/blocking fails for section "lfuFuncsCpu1Cpu1" size 0x914 page 0. Available memory ranges:
RAMLS1_5 size: 0x2800 unused: 0x458 max hole: 0x458

This says there is unused memory so do you think it is a trampoline problem? Here is my cmd file.

Hi again Vamsi,

I had read the document you had referenced and I thought I was using the techniques with these lines:

lfuFuncsCpu1Cpu1 : LOAD = FLASH6 | FLASH7 | FLASH8,
RUN = RAMLS1_5, //RAMGS10_15,

It turns out that I needed to change the second line to

RUN = RAMGS10_15,

as the LS1_5 apparently was not large enough. My program keeps crashing because I keep finding new functions that need the linker pragma added. I really did not expect to find actual function definitions in header files. I think I have copied the necessary flash api files to my project directory and have removed flash api from my include options. So it is tedious but I think I am on the right path. You asked if the function was in flash or ram and then I immediately knew what I had overlooked.

I will leave this unresolved until I get a clean run but I think it is solved. What is of the greatest concern is trying to set up the link file so that library function can be loaded in flash and run in ram. The simple trick of applying pragma statements can not be used in this case.

Thanks again,

John
