Hello,
I'm developing simple board with MCU having to store configuration data and based on them init another devices on the board. So I decided to use internal EEPROM emulation to store the settings (they could be changed over UART, so that's why I don't burn the setting hardcoded).
But I'm having a trouble setting NVMCTRL_EEPROM_SIZE fuse using Keil uVision and Ulink2. I simply didn't find any place where to set the fuse. I successfully added Microchip/ATSAMD20E18 chip (didn't find Atmel which I actually have) device to have proper programming algorithm, but nothing more than address range and erase/verify options found.
I spent whole day trying to get an access to the fuses, but without any success.
Another option is to purchase SAM-ICE for Atmel Studio where the fuses are available, but as I have Ulink2, I'm trying to use it first.
Any ideas?
Thank you very much!
John
