[jornada] Re: Bootldr on HP Jornada 567

Everyone,

The hardware (in particular, the custom ASIC) on the Jornada 56x series
is quite different than the iPaq. With the help of HP Singapore, I have
been able to get a version of the bootldr and linux kernel tree
working (without touchscreen) on the 560.

Please do not try to update the bootloader yourselves! When a stable
version of the bootldr is available, I will post the sources, binaries and
a Wince executable on the handhelds site.

Thanks,
jca
