Other Parts Discussed in Thread: UNIFLASH, NOWECC

 Now I know how to use nowECC tool. But also I have two question.
My IDE is IAR. I use the IAR to produce the file.out and file.hex, which format file should as the input file?
In the nowECC user guide, the input file should be one of this(Extended Tektronix;Intel Hex;ASCII Hex;Motorola S;COFF;ELF). But also in the nowECCuser guide,there is also an example:nowecc -i file.out -f021 16M_ADD -o file_ecc.out. The input file is file.out. which input file should I choose?

When I choose the file.out as the input file, there is no error . If I choose the file.hex as the input file, there is an error.
My device is tms570ls3137, this is my command:nowecc -i file.hex-f021 16M_ADD -r4 -a -o file_ecc.hex.
what's wrong with me?

Can J-TAG be used to load to the flash?  Does nowflash or uniflash sopported J-TAG/T-LINK? If not, what should I do? Should I must my debugger or change my IDE to CCS?  If can,what's the steps?

    Hi user4426369,

    Sorry for the delay in responding, I'm looking back at unanswered posts and came across this one.

    Since the IAR tools create ELF (EABI) output format for an ARM target, I would use the output file from IAR directly as the input to nowECC.
    You could try either using the -a option from nowECC to append ECC data to the .out file after the build, but before the download.
    I haven't tried this myself but if you give the same name for input and output files, hopefully it should just add the ECC data to the same file that is normally downloaded by the IAR Embedded workbench.

    If that doesn't work - you can output the ECC to a separate .out file (don't use the -a option) and then try adding this as an 'extra image' under the Project->Options->Debugger->Images tab.

    You shouldn't need any special debug probe or CCS - whatever you usually use with IAR you should be able to still use when you add ECC.

    Best Regards,
    Anthony
