Hello, Community
Previously, when I asked about how to recover from an abnormal image written on the MCIMX7SABRE board, I was advised to boot from an SD card.
Thank you for your suggestion!
I could start up from the included SD card with reference to the Quick Start Guide.
However, when I started U-Boot and tried to erase QSPI flash with the "erase" command, it did not work.
I tried other flash related commands ("flinfo", "protect"), but they didn't work as well.
There was no response to the command.
Do you know why?
If the QSPI flash erase method is wrong, please tell me the correct method.
I attached the image of the PC terminal at that time.
Best regards,

Hi, igor
Thank you for your reply!
I tried to check, but the "sf" command was not available.
There seems to be a similar problem as shown in the thread below.
How to add uboot "sf probe" command
If it is the same problem, the specified resistors has been populated on the board.
So, does the following statement mean that we need to rebuild U-Boot?
------------------------------------------------------------------------------------------------------
also please check uboot configs CONFIG_SYS_USE_QSPI
in include/configs/mx7dsabresd.h
------------------------------------------------------------------------------------------------------
Is it possible to erase the QSPI flash using the U-Boot included in the SD card included with the MCIMX7SABRE board?
