Hi Stefan,

Thanks for replying! I actually found out the reason for the discrepancy by
accident last week - that flash has an OTP section that's locked so the 2k
that's unavailable will be down to that. Reflashing and reconnecting
everything got me going again so I'm now chasing down a CFE bootloader for
the BCM6328 chip in this router :)

Cheers!
