CCS/TMS570LC4357: Fapi_issueProgrammingCommand () can't use the "Fapi_DataOnly" mode

Hello,

if Fapi_AutoGeneration option is used, the function will program the supplied data portion in Flash along with automatically generated ECC. ECC is calculated on 64-bit aligned addresses up to the data width of the bank. Data not supplied is treated as 0xFF. This means that the 0x00340004 has been programmed. 

hello 

I understand it.

if you have a good way for implement the following function:

for example:

1. I need to write 44 bytes data into the flash first, actuall, it write into 44bytes right data and 4 bytes 0xff; (flash address 0x003E0000~0x003E002C is right data, 0x003e002D~0x003e0030 is the 0xff)

2. Then I need to write 4 bytes into flash(the address is : 0x003e002D~0x003e0030)

if you have a way to implement it?

I try to read 44bytes data from the flash and saved it into a buffer, write the 4 bytes data into the buffer, and write the 48 bytes data into the flash.

but I think it too slowly.

if you have a better way?

Hello,

Can you combine the 44-bytes and 4-bytes in your first write? 

You can try this way:

1. program 44-bytes data using Fapi_DataOnly 

2. program 4-bytes data using Fapi_DataOnly 

3. program ECC for 48 bytes data using Fapi_EccOnly
