TMDSEMU200-U: Issue uploading firmware

Part Number: TMDSEMU200-U
Other Parts Discussed in Thread: RM48L952, UNIFLASH

Tool/software:

Hi Team,

Our customer has encountered an issue on the two units of TMDSEMU200-U which they purchased recently. Since he's currently unable to post and the board is still within warranty, I'm posting below on his behalf:

We purchased two units of TMDSEMU200-U and unfortunately, both units appear to be malfunctioning. When uploading firmware to the RM48L952 device using the XDS200 unit, the LED initially flashes but soon turns off, after which the UniFlash program fails to recognize the device. The same issue occurs with both units, and it persists even after changing cables and testing on different PCs.

Please let me know if you need further information on their debug probe set-up.


Kind Regards,

Jejomar

    Is this RM48L952 is TI board or custom board?

    If it is a custom board then please share its schematic or at least JTAG connectivity in the board for verification?

    Hi Jagadish,

    My apologies for the delay. We are still asking the information you need with the requestor which needs the information from their end-customer.

    I'll get back to you on this once we have the end-customer's feedback. Thank you!


    Kind Regards,

    Jejomar
