My cw1200 device cannot start again.
I tried to upgrade CW 1200 firmware, so I followed under link : Updating Firmware — ChipWhisperer 5.6.1 documentation
During the upgrade firmware process, especially after verifying message, suddenly my cw1200 device shut down. So I disconnected the power after 3 minutes because I think if I connect power again, the device would be rebooted again. But CW1200 cannot turn on even the power is offered and PC cannot detect the CW1200 device.
So, I researched some methods to resolve this problem. I tried to directly connect pin 137(erase pin) of Atmel ATSAM3U2E to a Vcc pin. This brough it back to bootloader mode, but nothing changed. So, how can I solve this problem?
