imx8qxp: imx-scu scu: RPC send msg timeout

[_angelo_]

Hello,

i am on linux-imx 5.4.70_2.3.0, on a custom imx8qxp based board

Only on certain reboots, generally, soft reboot, i get this message:;

imx-scu scu: RPC send msg timeout

as

[ 4.069200] 003: imx-scu scu: RPC send msg timeout
[ 4.069227] 003: imx-secvio-sc scu:secvio: Fail read secvio config -110

[ 7.142033] 003: imx-secvio-sc scu:secvio: Failed to get secvio state

in such cases, i then get a constant error over time

Hello,

The error printed in kernel log shows that the message sc_seco_secvio_config sent by SCU to SECO callback failed.

Could you share a bit more information, like how easy is this to reproduce?
Have you tried to reproduce this on a MEK board?

Best regards,
Aldo.
