Re: [Gumstix-users] Bluetooth, 802.11, and Etherner Not Working Out of Box

Dave,

Thanks for the info; I'll give it a try. I can see how this might explain the 802.11 and ethernet problems but could it also explain the bluetooth problem?

The gumstix are being shipped with an image for the netCF board. You
can either grab the latest buildroot, or try a precompiled image I put
together over here::
<http://www.davehylands.com/gumstix-wiki/verdex-1533-wifi/>

You'll want the rootfs and uImage files. You'll probably want to
update u-boot as well, if you want to use the microSD card from within
u-boot. Use the u-boot-911x.bin file.

To reflash u-boot, you need to drop into the u-boot GUM> prompt by
pressing a key on the serial console during the 3 second countdown
that happens at boot time. I normally use the serial console and
Y-Modem file transfer:

loady a2000000
crc32 a2000000 $filesize

Verify that crc32 matches crc32 of source u-boot. For the one
mentioned above, the correct CRC is 0x869cea29. if the crc doesn't
match, don't proceed.

protect off 1:0-1
erase 1:0-1
cp.b a2000000 0 $filesize
crc32 0 $filesize

the erase instruction above erases the flash, so if anything happens
(like you lose power) between then and the successful completion of
the cp.b command then your gumstix is bricked.

If the second crc fails, then you'll need to redo things. It's very
important not to poweroff or otherwise reset the processor between the
erase command and a successful crc32 command. You can always
redownload, and reerase.

Once u-boot has been upgraded successfully, then you can do a

reset

and it will reset the processor and run the new u-boot. You should see
the revsion number updated. I normally prefer to use the microSD card
to transfer rootfs and uImage since they're so large.
