After the “Starting kernel …” the message
gpmi-nand 33002000.gpmi-nand: mode:5 ,failed in set feature.
is printed, even when the boot is set to quiet.
Is there a way to fix or suppress this message?
That message comes from a GPMI-nand driver when it fails to set high speed mode. It doesn’t affect functionality since it continue to work in normal mode. You can either replace dev_err by dev_info to suppress that message in a quite mode or switch to 5.x BSP where GPMI-driver was redesigned.
