Hi,
I have a Compulab Utilite cm_fx6 in my lab but I am not sure how to make it boot.
I am using:
dd if=u-boot-with-spl.imx of=/dev/sdt bs=1K seek=1
It does seem to detect an image on the mmc (since it doesn't boot from SPI flash), but SPL and U-Boot output nothing.
Does anyone have any ideas? Perhaps this device is a bit old.
Thanks, Simon

"Booting from an SD card
Plug the SD card into the SDIO3(BOOT) SD card socket of the SB-FX6 Hold the BOOT SELECT (SW5) button while resetting/powering on the CM-FX6 evaluation system The CM-FX6 will boot from the SD card"
Do you think this helps?

Thanks for the reply.
For whatever reason, it does actually boot from SD if there is an image on there, otherwise it boots from SPI. It seems to be automatic. If I remove the SD card, it boots from flash.
I can write a really old image and it boots OK. It is just mainline which doesn't work.
