Theoretically I could use a u-boot image to encapsulate the second u-boot and use 'bootm', but I think I'll stumble over the same kind of questions.
There is already 'dcache off' but I wonder if something like 'go prepare' would be useful? Another option is that bootm has a prepare state, but it requires an image.
I agree with Simon. If you have not changed your target, you are using a MX31 and what cleanup_linux for arm1136 does is turning off the caches. What about if you turn off i-cache and d-cache in einem script before the go command ?
Best regards, Stefano
Hi Stefano,
cleanup_before_linux() also disables interrupts and flushes the cache(s). Simply turning off the caches did not do the trick.
Using 'go prepare' would be a solution as the 2nd argument should be an address (i.e. numeric) in any case.
Thx, Helmut
