1LC Set Address Error

[Phaedrux]

Can you please try flashing the firmware on the board first? It's running a beta version of 3.4.

@Phaedrux I have updated the firmware to version 3.4.4,and the problem is still occurred。

[Phaedrux]

When and where did you purchase the 1LC?

[iDavidFeng]

@Phaedrux I did it by myself,The other works fine

@iDavidFeng said in 1LC Set Address Error:

Error: M952: Failed to write NVM user area, code -17

FRom DC42: that's an error coming from the Microchip library "ERR DENIED"

[iDavidFeng]

@Phaedrux Is there some solutions to fix it?

[dc42]

@iDavidFeng it looks to me that when you programmed the SAMC21, you may have set the security bit. That prevents RRF from writing the user area, which is where the CAN address is stored.

It may be that a chip erase will clear the security bit. Check the datasheet.

@dc42 I have erase the chip and reflash the bootloader,but the board request for update firmware for EXP1XD,not the 1LC

[iDavidFeng]

@dc42 I have reflash the bootloader V2.3，and solve the problem. The V2.4 bootloader requests the wrong firmware for update

[dc42]

@iDavidFeng perhaps you used the wrong value board ID resistors when you assembled that board.

@dc42 ok，I will check it.Thanks
