Re: [microblaze-uclinux] uCLinux cannot allocate EMAClite interrupt

I can compile and boot uCLinux (without networking support) on
MicroBlaze without Flash and EMAClite. However, if I add networking
support to uCLinux and EMAClite to MicroBlaze, I get the following error:

It looks like interrupt 2 cannot be allocated to EMAClite because it is
already allocated to UARTlite. But according to auto-config.in (see the
attached file), interrupt 3 (instead of interrupt 2) should be allocated
After you copied the auto-config.in file across, you must do
$ yes "" | make oldconfig
$ make dep all
The petalinux-copy-autoconfig script does this as part of its operation
- if you aren't using it you need to do it manually.
In reality if you are changing the hardware like adding a new
peripheral, it's probably a good idea to do a "make linux-2.4.x_clean"
as well, to force a complete rebuild of the kernel.
This should get things consistent again.
