Is I.MX8MP EVK bootable from on-board spi flash?

[srainey]

On the i.mx8mp EVK, is the imx bootable from the on-board SPI NOR Flash? It looks like there's a pre-programmed image that begins with the correct IVT header, but putting the boot switches in SPI 3B mode (0110) does not seem to work.

When the board powers up in the mentioned mode, I do see 3 short bursts on the SPI bus with the clock at 20MHz, which doesn't seem to match any description from the reference manual.

Hello srainey.

I have a try with pre-built image on my side, and it works fine.

I have tried two methods with success.

One, the uuu file, example_spinor.uuu which I attach it here, you can copy it to the directory where you have your images.

then, go command prompt: uuu example_spinor.uuu

the other,  uuu command line which is like: uuu -b qspi imx-boot-imx8mpevk-fspi.bin-flash_evk_flexspi

A gentle reminder, There is actually QSPI Nor Flash.

Please feel free to reach out us, if you have any further question.

Best regards
