Re: [Gumstix-users] errors after reflashing, maybe messed up partitions

Oh, and one more thing -- might be safest to re-poke the MDREFR=20
register on the PXA before trying to flash stuff...

You'll need to change the low-order byte and a half of the MDREFR to=20
018, which means:

md.l 0x48000004

<will print some value>

mw.l 0x48000004 0xNNNNN018

<where those N's are from the value printed above>

This will increase the RAM refresh rate to the correct value for that=20
reboot cycle.  If you reset the gumstix before installing the new=20
u-boot, then you'll need to do that again.
