Can someone please explain a bit more what the deal is with upgrading Debian (or if necessary Armbian) Linux from the 4.4 kernel provided by Radxa to a newer version ?
I have been reading through some threads, but i am still completely confused as to whether or why upgrading to a newer kernel would be different from e.g.: debian on x.86
-> What is my easiest option to get a running debian (or if need be armbian) on a rockpi4 ? I have the radxa provided 4.4 kernel debian running fine on my rockpi4, but i think i have one kernel issue, and i would like to check if it still exists in latest debian kernel (5.3 or so ?).
-> Are there simply no newer kernels on the repositories ? And the repositories are hosted by radxa, and radxa does not care (has time/money) to compile newer kernels ?
-> Why do there need to be rockpi4 specific kernels anyhow, why can there be no more “generic” kernel to avoid having to compile for each different model ? There is enough memory these days to carry boodcode for many many SOCs, right ?
-> where are instructions how i could compile / upgrade myself on debian, and why would that fail more likely than on x86 ?
Thanks so much.
