firmware: omnia-mcu-firmware: Bump to 4.1
Bump omnia-mcu-firmware
to version 4.1.
This version fixes the following issue on boards with GD32 MCU:
- the user has old GD32 MCU bootloader and application (version 2.0)
- the user upgraded MCU application firmware to newer version (from 2.99 to 4.0)
- the user wants to upgrade application again, but it is impossible, because when MCU application firmware jumps into the old MCU bootloader firmware (2.0), the old bootloader firmware gets stuck in exception
- the user has to restart the board and upgrade the bootloader firmware first, which is not ideal, since if bootloader firmware upgrade is interrupted, the board gets bricked
Therefore the omnia-mcutool
utility version 0.3-rc3 will refuse to
upgrade MCU application firmware to versions 2.99 to 4.0 if the MCU
bootloader firmware is at version 2.0.
For users to be able to upgrade MCU application firmware on GD32 boards, they will need this new 4.1 version.
Users that already upgraded the MCU application firmware to a version
between 2.99 and 4.0 (using a previous version of the omnia-mcutool
utility) have no other choice but to upgrade MCU bootloader firmware as
well.
