It might help if you specified which version of U-Boot you run and for which board it is built. Note that if you're not using the mainline U-Boot but a custom vendor one, you should inquire with the vendor. Note also that if you're using the mainline U-Boot, then you should make sure you're using the latest version. > Regards, > Balaji. Amicalement, -- Albert.
