I do not have a waysmall or tweener expansion pack. I have a CF
stix, and an audiostix. To date, I have communicated with my
gumstix via bluetooth (post-boot) and the LAN (both wireless and usb).
Is there a way to replace the root file system image without a
waysmall or tweener?
You can do it with any of the following methods:
1. serial port using kermit (requires waysmall board)
2. read from MMC card using mmcinit/fatload (requires gumstix-F or if
you have one of the latest u-boots installed on your gumstix - since
r479 - then you can use a netMMC card)
3. read from network using tftp or NFS (requires netCF, netMMC,
netDUO, or netStix)
Note that you can upgrade u-boot from within linux, by doing:
1. In u-boot, interrupt boot, and enter "protect off 1:0-1 && bootd"
2. Wait for linux to boot
3. get the u-boot.bin onto the gumstix, let's say it's at /tmp/u-
4. flashcp /tmp/u-boot.bin /dev/mtd0
Note that if you don't do the "protect off" in u-boot, then linux
won't be able to write to the first 2 sectors of flash, since they'll
be hardware write-protected. u-boot will re-protect those two
sectors every time you reboot.
