IWR6843ISK: Software flashing via XMODEM fails frequently from SBL

Part Number: IWR6843ISK

Hello Team,

I wanted to update the software keeping the board in functional mode SOP setting. I referred your SBL document provided in the SDK 3.3.0.3, it suggests me the feasibility of flashing via XMODEM from the SBL. The procedure works in general after powering ON.

But, after some n times it seems to get hanged and XMODEM fails to transfer. I tried to assert an NRESET via a push button it reboots and again fails to send the file over XMODEM-1K. I have attached the screenshots of this issue.

Any suggestions on how to resolve this?

Thanks,

Dinesh
