Supporting for RM57 ECC failure

Other Parts Discussed in Thread: SEGGER

Currently, I am using TI embedded development board with RM57LS843. Now, I met an issue.

There is always a red lighten LED which marked "D1" in HW circuit diagram on my board. Once I push reset button, LED will be extinguished, but once release the button, LED will still lighten.

 

Now, I used the JTAG to flash the program to the target board, the failure still occurs. The failure prompt is "Can not find ICE-Pick(IRLen mismatch) TMS570/RM4x(connect) : Can not find ICE-Pick(IDCODE mismatch), Expected 0x0B00002F, found : 0x00000000 Session aborted!".

And if I used the SEGGER tool to abrase the flash, the failure error also occurs. refer to attachment

    Jia,

    IcePick should always be visibile so something major is wrong.

    Please check:
    1) that the external JTAG light is lit, this is DS1 "EXTJTAG" under the header J4 on your HDK.
    if you plug a Segger JLINK into this J4 you also need to see the LED lit.

    2) check the 4 power LEDs in the top right DS5, DS3, DS4, DS2, all need to be lit.

    3) make sure nPORRST isn't low. I think you can probe this at switch S4

    If all these are good try connecting using the USB connection and the on-board XDS100v2 emulator instead of the external Segger JLINK - just as a debugging step. At least see if IcePick is detected through the on-board emulator.
