Hi,
I'm using a board like imx8qm-mek. After a resume kernel print out the error. I found out the code in the file kernel_imx/drivers/gpu/drm/bridge/cadence/cdns-hdmi-core.c:
/* HDMI FW alive check */
ret = cdns_mhdp_check_alive(mhdp);
if (ret == false) {
dev_err(dev, NO HDMI FW running\n");
return -ENXIO;
}
What does it mean? What power system can i use to manage the power supply(SW1,SW2)?
