You cannot solve these problems by downgrading to PPCBoot. The 852/859/866 processors are definitelu *not* supported by PPCBoot - the required changes of the clock handling were added much later. You *must* use U-Boot. > As far as you know to change the boot or the kernel on cards in field is not > so easy :-( You mean you shipped boards to customers in the field in a state where you did not even decide for a final version of the boot loader?

U-Boot is running perfectly fine on the TQM859 - we have these boards here in our virtual lab; they are tested on a regular base. > I will try to introduce the U-Boot, but I am not confident it will solve the > problem, what do you think about it? I can *guarantee* you that PPCBoot is definitely worse on your hardware. > Last question, which is the appropriate mailing list? u-boot-users Best regards, Wolfgang Denk -- Software Engineering: Embedded and Realtime Systems, Embedded Linux Phone: (+49)-8142-66989-10 Fax: (+49)-8142-66989-80 Email: wd at denx.de Always leave room to add an explanation if it doesn't work out.
