Part Number: TMS320F28377D
Other Parts Discussed in Thread: UNIFLASH,

Hi all,

In my project I use custom board consist of TMS320F28377D.CCS Uniflash used to do flash the program and XDS100V2 device use as the Debugger .But some board was unable to flash the program because its shows error before flashing.

But interesting thing is that 'if I flash a new firmware file to working board and then use the same CCS uniflash workspace and debugger without disconnect from the same workspace then it can able to flash the faulty board.

please give any idea to resolve this issue.

Thanks in advance

    Jojo Mathew,

    What is the error that you got from UniFlash?  

    What version of UniFlash are you using?

    Did you try to use the latest UniFlash version and see if that clears the issue?

    Please take a look at: https://e2e.ti.com/support/microcontrollers/c2000/f/171/t/729543?-FAQ-Product-Change-Notice-PCN-20180523001-1-for-TMS320F2837x-and-TMS320F2807x-devices

    Thanks and regards,

    Jojo Mathew,

    You said you updated the SW.  Just to confirm: What is the UniFlash version you updated to?   As per the link that I shared, if you use a version of UniFlash prior to UniFlash v4.6, you need to update to UniFlash v4.6 (for 32-bit windows) or UniFlashV5.X (or higher for 64-bit windows).

    Please confirm the version you are using.

    Thanks and regards,

    Vamsi
