[Voyage-linux] Max CF size for WRAPs/ALIX

[Edwin Whitelaw]

As it becomes increasingly difficult to buy a CF smaller than 1GB, it 
begs the question as to the maximum CF supported for use in the now 
discontinued but still serviceable WRAP boards.  I've installed Voyage 
for WRAP on a couple of 1GB SanDisk CFs  and while it did boot, there 
were a number of errors that looked uncomfortably like those from a 
failing hard disk (details can be provided) and the boot time was very 
long.  I have been able to get some 512MB CFs but as of the last few 
days, those products are no longer available.

Also, the same 1GB CFs loaded for ALIX boot in 30s and run without 
error, but they only show up as 512MB.

/var/log/dmesg shows:

hda: SanDisk SDCFH-1024, CFA DISK drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
Probing IDE interface ide1...
hda: max request size: 128KiB
hda: 2001888 sectors (1024 MB) w/1KiB Cache, CHS=1986/16/63, DMA
 hda: hda1

but df returns:

tmpfs                     8192       360      7832   5% /rw

I preformatted the CF before running voyage.update.  Did I do something 
wrong here?  Is the update script re-running fdisk, mke2fs, etc?

Granted, I can't see any immediate need for more than 512MB but it does 
seem strange to have what could best be described as an artificial 
limitation.

Comments?  Enlightenment?

Thx,

Edwin
