Board:rca/rm4100

The RCA RM4100 was originally designed by Thomson Electronics and was called the IP1000. I was then manufactured by RCA and named the RM4100. It is a great little set-top-box for coreboot.

Building a coreboot image

Before building coreboot for the RCA RM4100 there are a few settings to consider.

1. Do you want to use VGA for your application?
You have the ability to build a “headless” version of coreboot that will only output to the serial console.

For a “headless” build follow these instructions:
Edit targets/rca/rm4100/Config.lb
Change:

# option ROM_SIZE = 1024 * 1024 

to

option ROM_SIZE = 1024 * 1024 

and change

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

to

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

Change:

option CONFIG_CONSOLE_VGA = 1 and option CONFIG_PCI_ROM_RUN = 1 

to 0

Change:

option CONFIG_VIDEO_MB = 8 

to 0

Edit src/mainboard/rca/rm4100/Config.lb
Comment out these lines so it looks like this:

#    chip drivers/pci/onboard		# Onboard VGA
     device pci 2.0 on end		# VGA (Intel 82830 CGC) 
#      register "rom_address" = "0xfff00000" 
#    end

If you do want VGA you can choose how much memory is pre-allocated for VGA. 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/rca/rm4100/Config.lb and change option

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).

2. Next you will need to prepare a payload. See the Payloads page for your options. For this Tutorial I will use filo to boot from a hard drive to Grub/Fedora Core 7. In the filo directory run

make 

like instructed in the INSTALL directions and then edit 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 or

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

to boot to grub on the harddrive (if you have the HD hack installed).

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/rca/rm4100/Config.lb to point to where filo.elf is.

3. Now we are ready to build core boot.

cd ~/coreboot-v2/targets
./buildtarget rca/rm4100
cd rca/rm4100/rm4100
make

If your using VGA to now need to prepend your video bios to the coreboot.rom. Copy your vga bios file (vga.rom) to the ~/coreboot-v2/targets/rca/rm4100/rm4100 directory and then:

cat vga.rom coreboot.rom > bios.bin

4. At last your ready to flash bios.bin to your RM4100. If this is the first time, meaning your rm4100 still has the original bios, you need to use the method on the RM4100 Customizing website to flash otherwise you can just use flashrom.
