Re: [microblaze-uclinux] uClinux on V4FX12
Hi Ron,

I have a working kernel on the Xilinx Spartan3E kit, and I created a
very similar platform for the V4FX12LC, but after I export the
auto-config.in file and build the kernel (with identical selections to
the Spartan config), I get absolutely no output on download. The only
obvious differences are that the processor is running at 100 MHz and the
DDR starts at 0x24000000 instead of 0x22000000. Both differences should
be covered by the auto-config.in.
Not sure where to start looking for a problem.
You are right that auto-config.in should cover all of this.
First thing I think is to confirm your hardware platform works as
expected. I'd be connecting to the platform via XMD, and doing some
basic HW level tests - reading/writing memory, confirming output to the
serial port by doing "mwr" write ops to the TX FIFO register, and so on.
The Xilinx-created TestApp_Memory and Peripheral EDK SW projects can be
good for this stuff.
After changing auto-config.in you shuold do a "make oldconfig" to ensure
the new settings get propagated through the kernel config headers. The
"petalinux-copy-autoconfig" script does this automatically.
Also worth doing a make clean and then rebuild.
Hope this helps,
John
