So FYI, in case anyone is interested and would like to share some advice. I tried running kernel 6.6 as first step, because I believe it’s probably the only way to have running CM5 on it, unless I would try compiling Kernel 6.1 with necessary modules (which I’m even not sure it’s possible).
Unfortunately 6.6 changed the way GPIO is accessed and also shifted UART device names, so as I don’t really want to change the code of Homey, I had to implement dirty workaround using sysfs-gpio-shim with some OS changes, but this workaround is probably not fully capable of taking over some of basic functionalities. So eg. since the upgrade I have been unable to reset Homey via PIN, enter ZWAVE learning/pairing etc. Other then that it was running fine for 2 weeks or so.
So this is “progress” so far, I would need first to fix those issues prior even trying to replace the module itself… if anyone is interested to share his thoughts … happy to hear some ideas.
