RA6M3 on EK-RA6M3 won't erase/program.

Hello,

I have an issue with programming/erasing the MCU on EK-RA6M3 via on-board J-Link or standalone J-link.

At first I was programming various codes to MCU without any issues, but all of a sudden an error occured, here are the screenshots from both Renesas Flash Programmer and J Flash     

I can detect MCU, read Flash memory, but cannot erase or program it anymore. Maybe some kind of protection was enabled, but I'm not able to figure it out.

Can you please help me ?

Thanks in advance for your reply.

Regards,
Filip.
