PXA320: No Output after decompressing kernelimage

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


Hello,

I'm trying to boot a Kernel (2.6.26) with Marvell PXA320 on an Trizeps5 module.

After the image was decompessed there is no more output on the serial interface.

I think the registers r0-r2 are correct set by the bootloader (r0 = 0, r1 = 1650, r2 = 0). The bootloader is not able to set some kernel_parameters so r2 is 0.

Is there any chance to debug next steps?

At which time use the kernel the pxa-serial driver?


Is it possible that the machine-parameters like .boot_params, .map_io or .phys_io are not correct?

greets 
Maik
