Re: [microblaze-uclinux] problems with download image.bin for kernel 2.6

Hi,
i sure that serial driver is not the problem, because i probe with the SAME hardware platform, and 2.4 kernel works fine, but 2.6 kernel does not. 

really? OK. Can you send me output from point 5?
i only want to know what options do i check or not in the "Customize Kernel Settings" Options, when i configure my kernel. only a simple configuration, only for 2.6 kernel can run on my board, only that. 

Can you send to mailing list your .config file? I check it.

    5. Do you use U-BOOT? U-BOOT helps you testing your design more
    carefully and helps you with booting kernel.
    If you use U-BOOT I recommend you check the log_buf of kernel

    # cat System.map | grep __log_buf (output is memory address)
    output is 441bf650

    in U-BOOT you can see output like this.

    If you see linux kernel log - you win. Your serial driver is not
    configured properly.
