TMS320C5517: programmer.out can't burn >64K .bin file to NAND flash

Shine

Part Number: TMS320C5517

Hello Champs,

HW: Customer own C5517 board
SW:C:\ti\c55_lp\c55_csl_3.08\ccs_v6.x_examples\programmer

Customer could burn <64K bin file to NAND flash, but failed to burn >64K size. He tracked the code in nand_flash.c, the fread function returns 0 and breaks out.

rcv_count = fread(FileData, 1, 2, pInputFile);
if (rcv_count == 0)
{
break; /* no more data to read */
}

I found below similar thread and sent him the flash programmer for 5517EVM, but it's the same issue.

Is there limitation in the source code?

The output is below

Thanks

Hi Shine,

You are correct. The fread() in rts55.lib does have size limitation of 64KB, because the num_left and num_read used in fread.c (rtssrc.zip in ccs\tools\compiler\C5500 Code Generation Tools 4.4.1\lib) is size_t which is unsigned int which is uint16.

Best regards,

Ming

Hi Ming,

Thank you very much.

Is there some method to fix this 64K limitation? Redefine size_t to unit32 and rebuild the rts55x.lib?

Hi Shine,

Changing the num_left and num_read in fread.c to use the uint32 may work.

Best regards,
