#Welcome to the PNX8550_U-BOOT wiki! This Wiki summarizes the current stage of the u-boot port for the pollin box.

##Status Currently working:

• booting to u-boot
• PCI scan
• loading elf-kernel over serial (kermit)
• booting elf-kernel <= 2.6.21
• Network: receive not working

Not working:

• Flash: ecc not working (different algorithm between WinCE and u-boot?)

Compile from source

Prerequisite

Following programs are recommend:

• ELDK 4.1 from DENX Software Engineering
• make 3.6 or higher

Compilation

To create the u-boot image for the pollin box (aka. silverbox), following commands should be used:

make silverbox_config
make CROSS_COMPILE=mips_4KCle-
./tools/mkpollinux u-boot.bin 00004000_00040000__loader.bin

The usage of the CROSS_COMPILE environment variable is mandatory, else the wrong endian will be used. After the compilation is finished, use the program "mkpollinux" located in the tools directory to create a WinCE compatible image. This can then be programmed through the flashme.exe replacing the elecard bootloader.

Installation
