Problem bootloader specified but missing


I have a little problem with the Arduino Progam.

I’m using a SODAQ Mbili board and I have this message :

Bootloader file specified but missing: C:\Users**** ****\AppData\Local\Arduino15\packages\SODAQ\hardware\avr\1.0.0\bootloaders\optiboot\optiboot_atmega1284p.hex

I don ‘t know how to solve that.

Could you help me ?

Thanks for your response

You seem to be trying to use v1.0.0 of the SODAQ AVR board files.

Can you try updating to the current version v1.1.0.

There was previously an issue with the checksum of the latest version (v1.1.0), which was preventing the board manager from completing the installation. This has now been fixed.

thanks for your answer

I will try your solution,
but to solve that, I put the bootloader that I found on the right directory and the problem disappeared

You should still use the latest version (v1.1.0) as there will have been other changes as well.
