A way to PalmOS-less device IV

This being probably the last article of the series, I decided to sum things up a little. But firstly, I have to admit there's still a minor issue. The system sometimes refuses to suspend and hangs instead. That is being worked on. I made some chart of support available here. As of now, the device is pretty much usable. My current setup looks like the following:

• xfce4 on debian-based rootfs running from 2Gb class-4 SD card
• Flash containing UBoot bootloader and basic recovery system (fits well in 16Mb)

Even though I think this kind of full-blown setup might be a little too heavy on a device PalmTC is, it copes with it well.

Now to the kernel stuff, as you might have found out in the previous posts, there are some files available, here's the list:

• Kernel config: .config
• Patches: Available here, apply on the following kernel tree
• U-Boot patch: available here

To compile kernel, do the following:

• Copy the downloaded .config to kernel source directory, apply all patches (use git am).
  
• make ARCH=arm CROSS_COMPILE=arm-something- menuconfig # this is not needed in case you don't want to modify the kernel configuration
  
• make ARCH=arm CROSS_COMPILE=arm-something- # this will get you arch/arm/boot/zImage (suitable for Cocoboot)
  
• make ARCH=arm CROSS_COMPILE=arm-something- uImage # this will get you arch/arm/boot/uImage (suitable for U-Boot)
  
• INSTALL_MOD_PATH=/somewhere/safe make ARCH=arm CROSS_COMPILE=arm-something- modules_install # this will install modules to /somewhere/safe/lib/modules/... You really don't want to mix them with your systems' modules

To compile U-Boot, do the following:

• Apply all patches (again, git am is your friend)
• make CROSS_COMPILE=arm-something- clean
• make CROSS_COMPILE=arm-something- palmtc_config
• make CROSS_COMPILE=arm-something- # this will get you u-boot.bin, the bootloader binary

You can use busybox to prepare some initramfs for your kernel if needed.
