Hi,
NOR is working fine in u-Boot and we are able to flash the uboot image and kernel image in to the NOR flash.
Also We have done the NOR(Non multiplexed NOR) configurations in kernel but after kernel boots from the NOR flash we are not able to see the Partitions.
Please let me know is anything wrong we are doing?
Attached the Log of what we are getting.
here below are the dts file entry for pin mux and nor configuration,
