General
The Kernel on the GTA01 is based on a vanilla 2.6.17.7 Linux kernel from kernel.org.
Some additional patches are required for
- S3C2410 Usb Device Controller
- We use the driver from iPaq H1409 linux project
- S3C2410 SD Card Controller
- We use the driver from the TomTom GO kernel
- QT2410 machine support
- This is just some glue that puts all pieces together
- S3C2410 touch screen driver
- Again from iPaq H1409 linux project
- GTA01 machine support
- Some glue/configuration to pull all pieces together
- GSM Communication Infrastructure
- The kernel-level part (TS07.10 line discipline, GPRS line discipline)
Kernel Patchset
The latest patchset against the abovementioned vanilla kernel can be found at [1]. This is a so-called "quilt patchset". In order to apply it, you have to untar it into a "patches" directory below the "linux-2.6.x" directory, and then call "quilt push -a", which pushes all patches onto the kernel.
Kernel Configuration
The latest kernel configuration can be found at [2]. Just copy it to the linux-2.6.x/.config file.
Kernel building
The kernel build is executed as normal. We actually only need the "vmlinux" target, not the "zImage".
bootable Kernel image
A bootable kernel image called uImage is available from [3]
creating a bootable kernel image
u-boot needs all images (such as kernel, initrd, ...) in the form of an uImage. This is basically just a special header adding CRC protection, version information, etc. Pleaes see u-boot for details.
Kernel Boot Parameters
The kernel image (once http://people.gta01.hmw-consulting.de/laforge/tmp/qt2410-biglcd.patch is integrated) has a new boot parameter "tft".
If you boot without any tft= parameter, the 'stock' qt2410 240x320 TFT panel is assumed.
If you boot with "tft=b" ('b' for big), the timings for the SHARP 640x480 TFT panel are used.
