Could not debug my new custom board

[fma23]

I am trying to debug my code using my new custom board that has iMX RT1062 MCU on it and a 16 MB flash on it: IS25LP128F-JBLE. 

I verified that my boot configuration is correct. I set it internal boot. However, when I run my debugger, I get the error below:

Break at address "0xdeadbeee" with no debug information available, or outside of program code.

I am using Segger debugger. Can any one tell  me what this error is all about?

[fma23]

What I am trying to do is that I want to program my board so that I can boot from an external flash using QSPI (part number: IS25LP128F.)

The board is configured to run QSPI, but when I use Segger Jtag to debug the code this is what I get in deassembly:

Hi Farid Mabrouk,

  Thank you for your interest in the NXP MIMXRT product, I would like to provide service for you.

  Please use the JLINK commander to connect your customer MIMXRT1052 board, can you find the ARM Cortex-M7 core?

  When you use the debugger, do you enable the QE bit?

   If you can find the ARM core, I suggest you use the MCUBootUtility tool to conect your board in the serial download mode through the UART or the USB HID.

The MCUBootutility download link:

https://github.com/JayHeng/NXP-MCUBootUtility/releases/tag/v2.0.0
the related user manual is:
https://github.com/JayHeng/NXP-MCUBootUtility

  After you test, you also can share your JLINK commander connect result, you also can tell me when you use the debugger, what's the IDE you are using?

Have a great day,
Kerry

Hi 

I used Segger jlink commander, and I was able to connect, and found the ARM core. Thus I don’t think the issue is the jtag, but rather a configuration issue. I’m using a 16MB flash. 

Do I need to have the reset and write enable pulled up high? I noticed these signals on iMX RT1060-evk development board are not pulled up high. How about config1 and config2, what should the values be? Config1 in my case is set to 1, config2 is set to 0x07; boot0 is low and boot1 is high. 

How do you Enable the QE bit? I read that Segger jtag is configured by default to run in QSPI. 

I’m using MCU expresso; and I’m using the GPIO example code to rest my board. 

Thank you, 

Farid

Hi Andre marcus,

  Thanks for your updated information.

  Please run this SDK code from the RAM with your JLINK debugger:

SDK_2.6.2_EVK-MIMXRT1060\boards\evkmimxrt1060\driver_examples\flexspi\nor\polling_transfer

  Please check can you do the external qspi flash erase, write and read operation.

  This code already contains the QE enable code.

   If this code can't do the flash operation, it means your hardware side still have problems, especially about the flash circuit.

  About the BOOT_CFG and BOOT_MODE configuration.

 All BOOT_CFG can be configured to 0, BOOT_MODE can be configured to the internal boot mode, BOOT_MODE[1:0]=10.

  BTW, do you also try the MCUBootUtility tool in the serial download mode, whether that tool can find the flash or not? That tool can help you enable the QE automatically.

  Please try it again.

Any updated information, please kindly let me know.

Have a great day,
Kerry

Im using this flash IS25LP128, by the way. Please comment on the pull up resistors for reset and write enable pins. Do I need pull up resistors or not. 

[kerryzhou]

Hi Andre marcus,

    IS25LP128 circuit should be the same as IS25WP064AJBLE, but just IS25LP128  is 3V power.

    About the pull up resistor for reset, do you mean the RT RESET pin? You can refer to the MIMXRT1060-EVK board circuit.

Have a great day,
Kerry
