I've downloaded the pre-bulit linux image provided by emcraft to STM32F746G discovery board using u-boot. The QSPI entry address is 0x90000000. After downloading the image I wasn't able to boot linux using the bootm command. The syntax is simple: bootm 90000000. I got the following error:

Wrong image format for bootm command

Error: Can't get kernel image

Any help?

p.s.: I am able to download and boot the image from sdram using the same commands

#uclinux #u-boot #emcraft #stm32f746 #qspi

EmCraft have their own website and support structures, don't expect to see a lot of support for it here. 

https://www.emcraft.com/

 

Dump the data at 0x90000000

Is the data there visible?

Is the image data in the correct format for u-Boot to use?

Is it built for the right memory location?

Can you script u-Boot to copy the image to SDRAM and call it?
