[U-Boot-Users] DiskOnChip problem on warm boot

[James Bates]

Thanks that was exactly the problem, I changed MAX_FLOORS from 4 to 1 and it
worked perfectly.

Regards,

James

Hi James,

I don't know about the "power on reset" vs. "warm boot"
aspect of your question, but I regularly get this behavior
when working with DiskOnChip devices.  I get around it by
determining (via printk) how many "floors" are detected
in my device at startup, then going back into the driver
and limiting the number of floors that are being probed to
that number.

What takes so long is the probing of nonexistent "floors",
at least in my case.

Chuck
