P1022 Custom board: Radeon problem

Question asked by Christian Zigotzky on Jan 13, 2015

Hi All,

 

I bought a P1022 custom board, last year.

 

Technical details:

 

P1022, Version: 1.1

2 core e500v2 1.2GHz revision 5.1

4 GB DDR3 RAM

PCIe x4 with x16 connector

U-Boot 2014.04-00124-g2c02fcb (Sep 20 2014 - 11:36:22)

OS: Debian 7.7 PowerPC and Debian 8.0 PowerPCSPE

Kernel 3.8.13-rt9 (config as attachment)

Radeon HD5450 1GB DDR3 VRAM

 

Debian 7.7 PowerPC and Debian 8.0 PowerPCSPE boot with the kernel 3.8.13-rt9 in the text mode without any problems. I can use X11 via fslfb (LCD) with the display resolution of 1024x768. But I can't use Debian with the Radeon HD5450. On U-Boot I have output with the Radeon but after the start of the Linux kernel, the screen has no output. But I saw with the serial console, that Linux booted without any problems and started gdm3 but unfortunately without screen output. I tried a lot of xorg configs and I played a lot with boot arguments for example video=radeonfb:1600x1200@60 etc but without any success. What I have to do to get X11 with the Radeon HD5450?

 

Cheers,

 

Christian
