Hey all,
I've been thinking. We've had a thread on i.MX platforms about fdt being overwritten and needing to be moved to another address. And I've also had an internal problem about fdt being overwritten. So, how about as a rule of thumb we start setting fdt_high (in configs) to memory-start + 512MiB, as that's the lowmem limit we should always have available. This will fix the problem of BSS overwriting the DT, which is the problem we won't catch in normal bootm/bootz usage. Thoughts?
Not sure I'm getting the issue clear, and I would like to avoid (me and others) having to switch back and forth between threads. Can you sketch the failure scenario in a couple of lines?
Amicalement,
