The difference between ver C and ver C2 on MIMXRT1170-EVK

[KoichiM]

Hi,

Regarding MIMXRT1170-EVK, let me ask.

I downloaded SDK using CMSIS-DAP with EWARM on verC board and could check the function.

For exp sample)

C:\XXXXX\boards\evkmimxrt1170\driver_examples\mu

And after getting new version C2 of MIMXRT1170-EVK, I cannot check the function 

due to CoreSight error without reading IDCODE. It means no SWD access.

According to this result, I think that new action is needed.

Can you comment something to this phenomena?

For exp)

I would like to understand if it is necessary for users to update CMSIS-DAP driver.

Regards,

Koichi

Hello Koichi,

From version C to C1 and C2 there was no layout change, but there were some BOM updates.

From C to C1:
1.Change C346 from 100nF to 100pF.
2.Change R368 from DNP 10K ohm to populate 100K ohm.
3.DNP R136 and default to use SD CD/DAT3 for card detection

From C1 to C2:

1. DNP Nand Flash U14 (MX30LF2GE8AB-XKI)
2. DNP R1821

I hope that this information helps!

Gustavo
