TMS320F28P559SJ-Q1: using API Fapi_issueProgrammingCommand() only program 64 bits each time

Hi Joe,

1. Are you trying to program and verify 8 16-bit words or 4 16-bit wods?

2. Also can you provide what is the content of poFlashStatusWord?

Please note that in Fapi_doVerify() function u32Length [in]  is the length of region in 32-bit words to verify..

Regards,

Rajeshwary

Yes, please see customer feedback, the u32Length is 2

Thanks

Hi Rajeshwary

Could you please kindly follow up this thread, customer changes the data buffer to 8 16-bit the issue still exists.

Thanks

Joe

Hi Joe,

Can you please ask customer to share the content of poFlashStatusWord in failure condition?

Also did they see correct data is programmed in flash memory?

Rajeshwary

Hi Rajeshwary

Please see attachment for customer feedback:

seem the error appears au32StatusWord[1] = 0x0000 0001 but au32StatusWord[2] = 0x0001 0027.

the data buffer is located at 0x535 the target flash address is 0x101400 

Thanks

Joe

Hi Rajeshwary

The root cause is that the offset of data buffer is wrong due to customer's wrong operation.

Thanks

Joe
