Uniflash 3.1 memory range not programable error message

Other Parts Discussed in Thread: UNIFLASH, TMS570LS2125

Hello ,

i just installed uniflash 3.1 and did "updates". prior i used 3.0

with 3.0 i never got an error messages while programming tms570ls2125

now after installing 3.1 and using the same boards and files i receives this

WARNING >> CortexR4: Loader: One or more sections of your program falls into a memory region that is not writable. These regions will not actually be written to the target. Check your linker configuration and/or memory map.

i confused about that ..

  • Pit,

    This seems to be caused by the change in the default value for the Auto ECC Generation option for these devices. For UniFlash 3.0, auto ECC is off by default, and in 3.1, we turned it on by default. You can get the same behaviour as 3.0 if you turned off the Auto ECC option.

    That being said, I'm still debugging when it is not allowing programming to the ECC regions during program load. I will update the thread if I discover anything.

    Thanks,

    Ricky

  • Pit,

    Just to follow-up, does the program you are loading contain ECC data? If so, it is expected that you need to turn off the Auto ECC generation option. The ECC regions will not be writable if the Auto ECC generation option is on.

    Thanks,

    Ricky
