Could not erase chip RA6M3G

Hello, @supporter.

I am working on an RA6M3G device.

I tried to erase the chip using J-Flash Lite V7.92c but was unsuccessful.

I used Jlink Commander V7.92c but still failed.

Could you please help me check it and give me the solution?

Thank you.

  • If you want to check what I mean, you can disconnect the connection between PC and board and supply 3.3V externally and try your connection because segger tool can not supply 3.3V. Did you try download any software with your connection before?
