TMS320F28P650SK: TMS320F28P650SK CCS12.8.1 Not erasing bank 2 and 3 when programming.

Part Number: TMS320F28P650SK


Tool/software:

Hi guys, the TMS320F28P650Sk as you know has 1.2MB of flash split into four banks. I've combined all of them into one bank named PETE_FLASH.

When I build and debug CCS12.8.1 downloads my assembler code (210k) it downloads perfectly and my code runs. 

When I build and debug CCS12.8.1 downloads my assembler code but this time my code is 443k.and fails at flash address 0x000C000. The error report is:

C28xx_CPU1: Flash Programmer: Error during Blank Check @ address 0x000C0000; expected 0xFFFFFFFF, actual 0x000D009C (0)
C28xx_CPU1: File Loader: Memory write failed: Unknown error

I went into the FLASH settings and chose BLANK CHECK and as you can see by the error 

FLASH BANKS 2, 3 and 4 is not being erased before programming. I went into the FLASH settings and I've chosen ERASE ENTIRE FLASH but as you can see FLASH banks 2, 3 and 4 is not being erased.

Is there a way of erasing them manually because it looks like CCS12.8.1 has a bug when combining all five flash banks into one flash bank even tho I've chosen erase entire flash in the settings.

I checked for updates and I'm all up to date. Does anyone have any ideas how to fix this problem? Please let me know as I need to combine all flash banks as one large flash bank to store large photos.

Thanks and hope to hear from you soon.

    Hi Peter,

    This has been resolved in latest version of CCS 20.2.0 .

    Thanks and regards,

    Thank you Charles this has fixed my problem. I really don't like the layout or CCS20 but if there's nothing else then I will live with it.

    One thing I noticed is after I've allocated ALL the flash banks to my flash bank PETE_FLASH the memory allocation windows shows PETE_FLASH 640k. I thought this was still wrong because the P650SK has 1.2MB of flash and then I realized that the flash memory is 16bit so it should be in words (16bit) and not bytes. So it really should say 640kwords. 

    Again thank you and have a great day. 

    A very happy PETER :)
