How to boot Qtopia from the SD card

This howto is probably incomplete. I also suggest not to directly copy paste anything from here, because I've written this after doing all the work. In case it's important, I used Fedora to do all this stuff.

Setting up u-boot

  • Get NeoCon and run it as follows:
sudo ./neocon -t 30 /dev/ttyACM0
setenv menu_1 Boot from microSD (FAT+ext3): setenv bootargs ${bootargs_base} rootfstype=ext3 root=/dev/mmcblk0p2 rootdelay=5 ${mtdparts} ro\; mmcinit\; fatload mmc 1 0x32000000 ${sd_image_name}\; bootm 0x32000000

(Thanks to Thomas B. for this fix)

  • Then save the environment by doing:

This should make the Neo boot from an ext3 partition on the SD card. The kernel can't boot from an ext2 partition currently even though it was the default setting for the bootloader.

Getting Qtopia and extracting the jffs2 image

Actually booting Qtopia on the phone

Insert the SD card into the phone, boot to NAND u-boot (again, not to NOR), choose Boot from microSD (FAT+ext3) and the phone should start booting Qtopia.

Other stuff

  • To make it clear, you boot into NAND by first pressing the Power button for a second or two and then pressing the AUX button while still holding down the Power button. If you do it "the other way around", it'll boot into NOR.
  • Neocon seems to sometimes "lock" the tty device completely to itself and the only thing I've come up with then is to reboot the host system.
