    I think the problem is in your connection. Did you supply 3.3V externally on your VCC pin of your Segger Tool and your board?

    Hello @,

    Because the RA6M3 device supports debugging on board, I using Micro USB to connect J10 (Board RA6M3) and PC.

    Can you connect with J-Link commander and read AWS register:

    >mem32 0x0100A164 1

    Hello,

    At the screenshot that you sent with Segger J-link to flash download, the process is stuck for long time or just 1-2 seconds?

    Also, on the J-Flash Lite V7.92c, do you see the same error  as your initial screenshot or something else?
