I need to go down to kernel 6.1 in order to be able to install the kernel module required by a Moxa USB to RS485 adapter. The module provided by Moxa warns on installation with and fails to build with I can see that there's still a bunch of 6.1 kernels available in the bookworm repo, so it should be possible to downgrade, but how do I ensure that I get all the associated RPi firmwares?
Code:
