Hello all,
(sorry for my frenglish) 
I’m currently experiencing a problem with the ExploRer board.
I would like to program the board in C from Atmel Studio without using the Arduino IDE.
The only problem is that it doesn’t work… In this example I only use the bootloader .hex from the samd21 ExpLoRer.
I can still generate the program but I can’t verify it … (return the address 0xFF) :
Verifying Flash…Failed! address=0x0000 expected=0xfc actual=0xff
I can read registers but the program doesn’t want to flash with the .hex file.
Have you ever experienced this problem and do you have any solutions?
Best regards,
ohtnaj
