OTP Memory burning failed.
Note that I do only have the SWD interface connected to a JTAG programmer. I do NOT have a UART connection. But since the SmartSnippets GUI works I am thinking that the hardware connections are ok. I have also checked the supply voltage and the programming voltage, both look ok.
Am I missing some step?
Does the "Burn" button call the "-type booter" before calling the "-type otp -cmd write_custom_code"? Do I have to call both commands?
I used the GUI Booter sidebar button just for testing the program: load the code to the memory without burning the OTP, check that it works, restart (disconnect and reconnect power and usb) and then go to the OTP Programmer sidebar button...
Thanks
