Hi,

 

As per the NXPs App note AN12239, no re-work required to test the HyperRam devices for iMXRT1050-EVKB. but when i compared the foot print of s27KS0641 with the kits schematics, the pin outs are not matching. can some one help me here. 

 

for HyperFlash, CS# pin is connected to ball C2. but for a hyperRam, CS# connected to ball A3 and pin A3 is floating in the board schematics.
