Can you flash master and check the output of dmesg?

Can you try these commands?

param reset
param save

[sevet]

param reset

This seems to stop the error but doesn't seem to save params

[julianoes]

@sevet has this been resolved?

[kh4lilo]

hello, i am having the same issue with the kakute H7, some params just refuse to be saved (PWM rate for example). any news abt this?

[julianoes]

@kh4lilo can you attach your param file and PX4 version? It could be that the PWM param is overwritten by your airframe (SYS_AUTOSTART) choice.

[kh4lilo]

@julianoes after some debugging and a lot of doc and forum reading, i found out that some params are forced during the init, specifically the rcS and rc.mc_defaults files, i changed what i need here and it works fine, thank you for you reply.
