In case this helps, when M7 crashes, Torizon OS console shows the following message
imx-rproc imx8mp-cm7: imx_rproc_kick: failed (1, err:-62)
@bruno.tx I’ve just found that this error is the same already reported by @aditya.yantra in this topic.
I’m going to do the checks suggested by @hfranco.tx in that topic and I’ll post here the results.
