radeon_cp: Failed to load firmware « radeon/R200_cp.bin »

I recently found this error in the output of the command dmesg:

“radeon_cp: Failed to load firmware “radeon/R200_cp.bin

It seems that there is a missing file R200_cp.bin requested by the radeon firmware.
To find the package to which the file R200_cp.bin belongs to :

root@localhost:~# apt-file search R200_cp.bin
firmware-linux: /lib/firmware/radeon/R200_cp.bin
firmware-linux-nonfree: /lib/firmware/radeon/R200_cp.bin

So, the missing packages firmware-linux and firmware-linux-nonfree must be installed :

root@localhost:~# apt-get install firmware-linux firmware-linux-nonfree

To verify that the missing file is correctly installed, restart your X server and check again the output of dmesg :

root@localhost:~ # dmesg |grep radeon
[drm] Setting GART location based on new memory map
[drm] Loading R200 Microcode
platform radeon_cp.0: firmware: requesting radeon/R200_cp.bin
[drm] writeback test succeeded in 1 usecs

  1. Thanks. That helped. Even though I mught have found that myself, it was faster to find it properly documented 😉
