I strongly recommend trying to bring up a 2.6 kernel, it's much easier. > and yes, the uartlite driver is enabled :) Don't modify xparams by hand; it's not worth the trouble. Go into software setting in your EDK project and select 'linux-2.6' as the OS. Generate the libraries and copy the generated xparameters_ml40x.h into your kernel tree. > > > but, when downloading the zImage.elf via XMD to the SDRAM and starting > it with the run command nothing happens , or i think that nothings > happens because the serial port is quiet. You can always use System.map in the kernel tree to find out where __log_buf was linked to. Look at that location with the debugger to see if there is a crash message that didn't get printed out. > > is it possible to run a kernel that way ? or need i some kind of > bootloader ? > or is this complete the wrong way ? Yes, I use this same method to bring up a kernel on Virtex boards which don't have a bootloader. -- Grant Likely, B.Sc., P.Eng. Secret Lab Technologies Ltd.
