Hi all, I have been trying to run linux 2.4.26 on Virtex 4 for a while and without success. I am trying to implement a simple design, with an UART, SystemACE and everything interrupt driven. When I try to make bzImage, there is an error in (SysACE) adapter.c file, because XPAR_INTC_0_SYSACE_0_VEC_ID is not defined. I have applied the patch given by Xilinx for switching from the ml300 to the ml403, which copies the bsp, .config and xparameter files into the kernel. I am stucked here, and do not know how to keep going from that. Could anyone help me a little bit? Thanks and have a good day!
