Hi,

I have both EVKA and EVKB of rt1050.

Our rt1050-based product need to use QSPI flash instead of hyper flash, so we are studying it.

I have followed all step of doc: AN12183, but I got different results below.

 

[EVKA: QSPI XIP Succeed]

According to AN12183,

(1) I removed the hyper flash and welded 0 ohm resistor from R153 to R158

(2) I updated FW of CMSIS-DAP (for QSPI NOR Flash).

(3) I changed flash setting code according to AN12183SW.zip and use IAR to run debug in XIP mode

The result is successful. System runs in XIP mode.

 

But when I used EVKB, I got failed result!!

[EVKB: QSPI XIP Failed]

According to AN12183,

(1) I don't need to remove hyper flash. I removed R356,R361~R366 and welded 0 ohm from R153 to R158.

(2) I updated FW of CMSIS-DAP (for QSPI NOR Flash).

(3) I changed flash setting code according to AN12183SW.zip and use IAR to run debug in XIP mode

The result is failed......

(4) SDK version: 2.4.0

 

We all knew that rt1050-A0 and EVKA were deprecated, so we need your help to solve the QSPI problem in EVKB ! Thanks!
