i.MXRT1050 with external NOR QSPI flash - no debugging enabled

Hi, all, I'm working on custom solution and trying to build application with NOR QSPI flash in memory map.

My memory map is as follows (using standard 1MB Winbond NOR QSPI flash):

Trying lo load application in debugger I get the following:

Why it doesn't work?

Thank you in advance

Hi @yanz,

Is there any additional information you can provide about this? With the information provided, it is not enough to be able to tell for sure. What process do you follow to start debugging your MCU? Is the flash properly connected? What code are you using?

Respecting the last question, If you are currently using a custom code, I would highly suggest you to try one of our example codes at this stage instead. This could give us some insight on whether the problem comes from the image or the flash device.

BR,

Edwin.

Hi,

I'm using SDK's flash_component_nor example, only Winbond NOR QSPI flash added to memory map.

I can communicate (read/write/erase) with flash, burn and boot from.
