SSD C55 FlashProgram() max size?

I think SSD C55 FlashProgram () max size is 0x800.(source_end 0x40005800 - source_start 0x40005000)

but flash wrote size only 0x80. so I change size from 0x800 to 0x80.

MPC5748G Internal Flash write success.

I think FlashProgram() size 0x800 is supported.

so i try your MPC5748G-Flash_RW-SSD_GHS614 project used T32.

The results were the same.

What is the SSD C55 FlashProgram() maximun size?

I hope this is the last question.......^^;;

Hi,

I found out that I didn't initialize these pointers in my example (this is copied from c:\Program Files (x86)\Freescale\Standard Software Driver v1.1.0\MPC57xx\Demos\Demo_code\common\demo.c):

/* set up function pointers in context data */
    pgmCtxData.pReqCompletionFn = pFlashProgram;
    bcCtxData.pReqCompletionFn = pBlankCheck;
    pvCtxData.pReqCompletionFn = pProgramVerify;
    csCtxData.pReqCompletionFn = pCheckSum;

The pointers are used by FlashCheckStatus function to call the functions.

I simply added the initialization like this:

and then it works as expected.

Thanks for pointing this out, I will update the example next week.

Regards,

Lukas
