Hi Bin， today I test the hardware of CS signal . I configure cs2 as a gpio . then write 0 , I catch low level . when write 1 , I catch high level. so the hardware of cs2 signal works ok . but configure cs2 to GPMC mode . when run devmem2 cmd ,the cs2 is always high level. so I am sure that gpmc didn't set cs2 low level when read the cs2 space address. so how to solve this problem ?
