Can anyone confirm later revs of the Olimex board fix that issue?
This is the late 2014 rev A5 errata - and how to fix the oscillator issue with A5, it may help with A4 too.
Solder in the 10kohm resistor to help oscillator start ..
Also I've seen somewhere you should not use the logic pins close to oscillator pins as they can disturb the oscillator when toggled..
Errata also says you
1. cannot use ceramic resonator for primary oscillator,
2. cannot use crystal for the secondary oscillator.
PS: As the MCHP erratas are probably written by none-technical staff - the "crystal oscillator" here means "the crystal". "External clock" means "external crystal oscillator" or any other kind of an external oscillator with appropriate output level and timing..
