Problem Programming QSPI Flash on custom iMX RT-1011 board

[gh78731]

Environment: MCUXpresso IDE V11.3.1, Windows 10,
MCU-Link connection via SWD.
MIMXRT1011CAE4A processor, Adesto 25SF128A QSPI

Custom design iMX RT-1011 board, bringing up for the first time.
Uses same AT 25SF128A QSPI Flash as EVK, connected to same pins as EVK
Has serial port in same location as EVK.

I am trying to bring up custom board for first time, using "hello-world" example from EVK.

If I load "hello-world" directly into SRAM, program runs as expected.
So, power supplies and clocks are up and running, and everything is connecting.

I can successfully Mass-Erase the QSPI Flash via the GUI Flash Tool.
The GUI flash tool can see the QSPI and properly identifies it as 16 MB device.

If I try to load "hello-world" compiled for XIP from FLASH into the FLASH,
I get programming error as follows:

Loading 'evkmimxrt1010_hello_world_II.axf' ELF 0x60000000 len 0x55F0
Opening flash driver MIMXRT1010_SFDP_QSPI.cfx (already resident)

(100) Writing Flash ended with an error.
File 'evkmimxrt1010_hello_world_II.axf' load failure: Ef(49): Flash driver operation gave error.
(100) Target Connection Failed

What does "driver error - EXTSPIJ driver rc -255 (0xFFFFFF01)" mean?
Any clue as to what is wrong?
Considering that these are brand new RT-1011 and QSPI parts, is there some additional configuration I need to do before I can load a program into FLASH via SWD?

Hello, I am using IMXRT1062 with same SDK example flexspi_nor_polling_transfer to my custom board. But , I got Bus Fault error and HardFault.

Please help me solve this.

Exactly what I was looking for.

Thanks,

Further information. 

It looks like I need to program the "QE" bit on the QSPI, as part of a new part configuration.

I would prefer to do this by executing some code loaded into SRAM via SWD interface, rather than setting up for serial interface. Is there some existing code to do this?

Same request for programming the OTP bits in the iMX RT1011 when it comes time to do that.

Hello Graham, 

Please refer to the SDK example flexspi_nor_polling_transfer. This project demonstrates how to set the QE bit with the function flexspi_nor_enable_quad_mode.
