Facing Problem while accessing NOR Flash chip from Linux MTD Driver for P1021 processor.

Discussion created by krishna chaitanya on Dec 29, 2016

We are Working on spansion s29GL01GT flash chip for p1021 processor. We are trying to add MTD driver in kernel and observed following error while booting.

Error : of-flash e8000000.nor: do_map_probe() failed

we went through MTD subsystem code and found that driver is unable to fetch the String "QRY" from the flash chip.

here i have attached Kernel Configuration, DTS and Booting capture files. please go through the attached files and help me in this issue.
