NXP dev board T2080 e6500 with Debian sid PPC64 and RadeonHD

This is our first successful attempt to setup a T2080rdb with a video card.
The RadeonHD 5450 is attached to the onboard PCI Express Gen3 4x connector using a 16x cable adapter.

We are using this board as it uses the same CPU (NXP T2080) as the one selected for our Open Hardware laptop project

You may find more infos about the board here

The system is a Debian sid PPC64 with packages available in the following repositories

Few software did not works without applying patches to make them work properly under PPC64 (see Midori, Firefox, Iceweasel, VLC, mplayer), so we setup our own repository


This the output of the Hardinfo 0.6 alpha benchmarks, compared to a PowerMac G5 (IBM 970) and a three years old intel laptop (i7-4600U).

Now some remarks
1) The Debian Sid was set up on the PowerMac G5 then, the 2.5’HD was attached to the T2080rdb onboard SATA. We used a vanilla 4.17.6 kernel image customized for this board (no patch applied) and a modified Device tree blob stored on the onboard SD card. You may find the U-Boot kernel image (uImage) and the Device tree (uImage.dtb) in our GitLab account
2) Not figured out (yet) how to go online using the T2080rdb onboard ethernet ports.
3) Games such as Chromium BSU or NeverBall simply works. Games such as SuperTuxKart does not start, Torcs is slow and the audio is completely corrupt
4) The T2080rdb works well with the RadeonHD 5450, but many errors floods the serial console whenever trying to plug in other RadeonHD cards (e.g. 4550, R7 250E which is a rebranded HD7750).

This is the error that floods the serial console:
pcieport 0001:00:00.0: AER: Corrected error received: id=0000
pcieport 0001:00:00.0: PCIe Bus Error: severity=Corrected, type=Physical Layer, id=0000(Receiver ID)
pcieport 0001:00:00.0: device [1957:0830] error status/mask=00000001/00006000
pcieport 0001:00:00.0: [ 0] Receiver Error (First)
