AN12239 board re-work

[vinaymanikkoth]

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.

what is the expected timeline for release of this updated board? 

i have already purchased 2 boards after reading your app note.

Unfortunately, there is not the expected timeline for it. Please refer to NXP website if any update. Sorry for the inconvenience may  cause.

may i know the method you followed to conduct the experiments mentioned in appnote. i would like to reuse.

meantime, please let me know, the timeline of the new board if possible

[vinaymanikkoth]

is there any workaround to use hyperRAM with current version of the board?

may i know how you performed the experiments mentioned in the Appnote?

Hello,

Thank you for your information. The current A1 version requires the customer to be compatible with ball A3 and ball C2. . The devices can be simply swapped without any other hardware changes required for B version in future. Please find the detail information as the attached. Hope it help you.
Have a great day,
TIC
