How to recover MCIMX7SABRE board loaded with an abnormal image

[yuichi_takeda]

Hello, Community.

I'm trying to debug an application by loading an image to the QSPI flash on iMX7D via JTAG.
The evaluation board used is MCIMX7SABRE.

One day, I accidentally loaded an abnormal program.
As a result, the image cannot be loaded again.

In the case of QSPI Boot, when the evaluation board is turned on, the abnormal program on the QSPI flash is executed, resulting in an abnormal CPU status, the boot loader cannot be executed, and the image cannot be loaded.

So I tried loading the image in a mode other than QSPI Boot, but I couldn't access the QSPI flash and load it.

How do I erase an abnormal image on the QSPI flash and load a normal image?

Hi Yuichi

also one can try to erase qspi, so processor jumped

to serial downloader mode and then program image with uuu

or Mfg Tool. One can follow documentation on

i.MX Software | NXP

Quick Start Guide.
