linux 2.4 on Xilinx ml403

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!

Hi,

libgen of EDK should generate the definition of
XPAR_INTC_0_SYSACE_0_VEC_ID as follows according to your design to
xparameters.h.

[snip]
#define XPAR_INTC_0_SYSACE_0_VEC_ID XPAR_OPB_INTC_0_SYSACE_COMPACTFLASH_
SYSACE_IRQ_INTR
[snip]

Have you copied xparameters.h which EDK generated to the kernel tree?

Best Regards,

Yoshio Kashiwagi

Make sure your system.mss contains something like:

BEGIN OS
 PARAMETER OS_NAME = linux_mvl31
 PARAMETER OS_VER = 1.01.a
 PARAMETER PROC_INSTANCE = ppc405_0
 PARAMETER MEM_SIZE = 0x4000000
 PARAMETER PLB_CLOCK_FREQ_HZ = 100000000
 PARAMETER connected_periphs = 
(RS232_Uart,IIC_EEPROM,SysACE_CompactFlash,Ethernet_MAC,opb_intc_0)
END

If it does not use XPS and in the menu select Platform Software 
Settings. Use linux as Operating System and linux_mvl31_v1_01_a as the 
MLD. The rerun the library generation. Also make sure that you have 
enabled the interrupts for System ACE CF in the hardware.
