Hi all,
I've recently purchased two ROACH boards from Digicom to use as a pocket
correlator (specifically, Zaki's old rpoco8 and/or rpoco4 designs). One of
my boards is a rev2, one is a rev3. I've run all these codes successfully
on rev2's in the past, and we have no problems with this rev2 using both
USB Boot and SD Boot. Using the exact same USB stick on the rev3 gives
does not work. Below is the boot-up log with what I take to be the key
error in bold (we don't see anything like this on the rev2). Is there
anything actually different about rev2 and rev3 with regard to USB Boot?
Or is our board acting problematically? I'm told we get similar behavior
with the SD card boot but haven't tried it myself.
Cheers,
Jonnie
