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.
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 @nskrkmz ,
Because the RA6M3 device supports debugging on board, I using Micro USB to connect J10 (Board RA6M3) and PC.
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?
I understand your mentions.
RA have 4 way to connect.
Hello quanvo,
Thanks for reaching out Renesas Community.
Can you try to initialize device back to factory default using Renesas Devision Partition Manager through e2studio, take a look below:
Please, inform us if you have successful initialization.

Hello AL_Renesas
This is the result when I apply your solution
Connection type:
- Need to correct SWD instead of SCI or not?
Supply voltage:
- Need to use an external power supply or not?
Hello,
Do you use your customized board with RA6M3 chip or the EK- RA6M3G ?
hello,
I use EK- RA6M3G.
Please, try to re-program your board with Renesas Flash Programmer and share with me a screenshot of the messages with specific error code you get.
I created the blinky project for ra6m3g and used RFP to flash.
1./
2./
3./
4./
Please, check the possible causes for your issue, below:
Regards
I checked the possible cause but was not successful.
I used 1 RA6M5 and ran Renesas Device Partition Manager/RFP. It's OK.
Is there any case of chip locked?
RTT Viewer still connects to the board normally.
If you have written data in Option Settinh Memory 0x400 in code flash, the only way to recover the flash is by trying the attached jlink script to erase the first block of code flash( as the Security MPU be enabled). If that doesn't work the device may be not recoverable.

=> I reset the board and re-debug again but did not success
Can you recall the sequence of operation that you used to flash you MCU the first time? Maybe this will help to understand what have happened.
Also, please check carefully the causes 1,2,3 Maybe, your usb cable or your power supply is the reason.
About the sequence of operation, I flash on MCU the first time,
I ran the unity test r_usbx_port project.
When I erase the chip.
I think it failed when erasing the range 0x010A150 + 32Byte.
This range is
