I'm running FreeBSD 7.0 on a soekris 4801 with an image built by nanobsd.
It's a small piece of headless hardware that boots from a compact flash drive
- no moving parts.
I wanted to update the operating system to 7.1 and install some more packages
on it, so I built a new image with nanobsd and uploaded it to the second
partition using nanobsd's updatep2 tool. The new image mounts fine, but the
last line of updatep2, "boot0cfg -s 2 -v ${NANO_DRIVE}" fails with the
message I've quoted in the subject line.
The machine boots fine, but I can't provoke any kind of response from
boot0cfg except for input/output errors. I'd like to make the machine start
booting from the second slice.
Any ideas?
More information...
The number of heads that the "diskinfo" reports is different depending on
whether the compact flash card is plugged into the soekris box or mounted
in a USB card reader/writer.
The usb reader/writer reports:
da0
512 # sectorsize
2052513792 # mediasize in bytes (1.9G)
4008816 # mediasize in sectors
249 # Cylinders according to firmware.
255 # Heads according to firmware.
63 # Sectors according to firmware.
The soekris box reports:
ad1
512 # sectorsize
2052513792 # mediasize in bytes (1.9G)
4008816 # mediasize in sectors
3977 # Cylinders according to firmware.
16 # Heads according to firmware.
63 # Sectors according to firmware.
This is the same compact flash card.
I gave up on boot0cfg and booting from the second partition, so I took the
compact flash card out of the soekris box, connected it to my workstation
with a USB card reader, and wrote a whole new image to it.
Even after doing this, boot0cfg still won't work. I noticed some new
messages on the console when I tried "boot0cfg -v ad1":
ata0: FAILURE - non aligned DMA transfer attempted
ad1: setting up DMA failed
boot0cfg: read /dev/ad1: Input/output error
ad1 is attached to ata0, per dmesg:
ad1: 1957MB <LEXAR ATA FLASH CARD 20060911> at ata0-slave WDMA2
I think this means there is some kind of geometry problem here, but I
don't know how to fix it.
I'd like to find a solution to this, but it's not critical.
