The Thomson IP1000 is designed by Thomson Electronics. It is the RCA RM4100's big brother. It is a great little set-top-box for coreboot. Linux has never been able to run on this board until now. Maintained by Joseph Smith.

A full bootlog of this board running coreboot is available for reference.

VGA vs. Headless

Before building coreboot for the RCA RM4100 there are a few settings to consider. Depending on whether you want VGA support or not, you might have to modify some files.

Headless (no VGA)

You have the ability to build a "headless" version of coreboot that will only output to the serial console:

Edit targets/thomson/ip1000/Config.lb and change:

# option ROM_SIZE = 1024 * 1024
option ROM_SIZE = (1024 * 1024) - (64 * 1024)

to

option ROM_SIZE = 1024 * 1024
# option ROM_SIZE = (1024 * 1024) - (64 * 1024)

Also, change:

option CONFIG_CONSOLE_VGA = 1
option CONFIG_PCI_ROM_RUN = 1

to

option CONFIG_CONSOLE_VGA = 0
option CONFIG_PCI_ROM_RUN = 0 

Change

option CONFIG_VIDEO_MB = 8

to

option CONFIG_VIDEO_MB = 0

VGA

If you do want VGA you can choose how much memory is pre-allocated for VGA. Note: You can still use the serial console when VGA is enabled. Possible options are:

## 0 for No memory pre-allocated (Graphics memory Disabled)
## 512 for DVMT (UMA) mode, 512K of memory pre-allocated for frame buffer
## 1 for DVMT (UMA) mode, 1M of memory pre-allocated for frame buffer
## 8 for DVMT (UMA) mode, 8M of memory pre-allocated for frame buffer

To adjust this edit targets/thomson/ip1000/Config.lb, edit the line

CONFIG_VIDEO_MB = 

and change it to any of the options above. Note: Remember that if you do want VGA you will need the VGA BIOS file (vga.rom).

Payload

Next you will need to prepare a payload. For this tutorial I will use FILO to boot from a hard drive (Fedora Core 7). In the FILO directory run

make

like instructed in the INSTALL directions and then edit the file Config.

Change:

MENULST_FILE = "hda3:/boot/filo/menu.lst"

to (menu.lst is a symlink to grub.conf and FILO does not like that)

MENULST_FILE = "hda1:/grub/grub.conf"

to boot to GRUB on the Compact Flash card or

MENULST_FILE = "hdc1:/grub/grub.conf"

to boot from the harddrive.

Change:

#SERIAL_SPEED = 115200

to

SERIAL_SPEED = 115200

to insure we get output to the serial console. That should be it. Now you can run

make 

again to build your payload ELF file. Once that finishes copy filo.elf to the /tmp directory, or you can adjust targets/thomson/ip1000/Config.lb to point to where filo.elf is.

You can further reduce the size of filo.elf by disabling various unneeded options in FILO's Config file (e.g. support for filesystems you don't use).

Building coreboot

Now we are ready to build coreboot.

$ cd ~/coreboot-v2/targets
$ ./buildtarget thomson/ip1000
$ cd thomson/ip1000/ip1000
$ make

If you're using VGA you need to prepend your video BIOS to the coreboot.rom file. Copy your VGA BIOS file (vga.rom) to the ~/coreboot-v2/targets/thomson/ip1000/ip1000 directory and then:

cat vga.rom coreboot.rom > cboot.rom

Flashing coreboot

At last you're ready to flash cboot.rom to your IP1000. Unfortunately there is not really an easy way to do this. The IP1000 has a PLCC32 socket for the firmware chip so you can take the chip out and use the Hot Flash method or a programmer device. After you have Linux running you can always use flashrom.
