Hi Wolfgang, thanks for the quick response.

I saw a Lite5200 on a picture somewhere and it looked pretty much like my EP board :-). But what I can tell for sure is: when I remove the "Embedded Planet" sticker on the board, there is a Freescale logo and a print (directly on the board): "IceCube Version 103" > > Coral-P (Rev 5.0).

(I had to adapt the Imakefiles by myself, the provided ones were too different from the originals.) In the meantime, I can provide you with further debugging information: from Xorg.0.log: ====== (II) MB86290(0): Using XFree86 Acceleration Architecture (XAA) Screen to screen bit blits Solid filled rectangles 8x8 mono pattern filled rectangles Indirect CPU to Screen color expansion Solid Lines Dashed Lines (II) MB86290(0): Acceleration enabled fbdevHW: LoadPalette 0 (II) MB86290(0): fbdevHWLoadPalette succeeded ====== The last line is a message that I added. Since the output stops at that point, it must be the next call that fails (mb86290_driver.c:604): if (!xf86I2CProbeAddress(fPtr->I2C, I2C_SAA7113)) return FALSE; May that be a problem with the i2c driver in the kernel which does not exactly fit with my board? The following message also appears in Xorg.0.log, some lines above: (II) MB86290(0): I2C bus "MB86290 I2C bus" removed. Thanks in advance for any hint that you can give me. Best regards, Matthias
