PEMicro MU unable to write RT1020 QSPI FLASH

We have a custom board using MIMXRT1021CAG4A connected to a ISSI IS25LP064A NOR serial flash memory (same as EVK for RT1020). We have debugged the example called "flexspi_nor_polling_transfer" provided in the SDK for the EVK first to set the QE bit. Image with the console output seems OK and id vendor matches.

Then, we tried to debug the blinking led example in the FLASH but when the session starts it crashes because memory is erased and never programmed (assumed seeing all 0xFF  in  dissasembly window). Image attached with a breakpoint in ResetISR.

When we tried using the GUI FLASH tool in the IDE we have this output:

 It is connected in the same way as the EVK (same pins), the QE bit was set and the debug session starts without errors or warnings. Why the memory wasn't programmed?

We are using PEMicro Multilink Universal

Hi @gtalocchino ,

   Do you set your boot mode in internal boot mode?

   From your RAM flexspi_polling test result, your QSPI flash already works OK, erase, write, read all OK.

   Now, do you have any other debugger except the the PEMicro MU, eg, Segger JLINK or CMSIS DAP, whether other debugger works OK or not?

  About the code, please use the SDK led_blinky, download it to the flash, your log indicates the readout data is not correct:

CMD>VM
Verifying.
Verify error at address $60000000.
Byte in module is $FF and should be $46

 So, you also can use the MCUbootUtility to download the app to your flash in serial download mode, and check, whether the readout data is correct?

Then check boot, if it works OK.

Then back to your PE Mulitlink, download again, use the MCUbootUtility readout the flash memory, whether it is the same as the APP image.

 If you have other debugger, also try it with MCUxpresso IDE.

MCUBootUtility tool:

 It seems to be MCUX flash algo issue under PEMicro, Can you please try another IDE? for example IAR.
