hi, I'm trying to port Linux 2.6 on Avnet FX12 MM board with U-Boot and the help of xilinx ML403 config.
I have generate my costum xparameters.h file with EDK 8.2i. I use ELDK 4.1 and Linux 2.6.20.x. I have modified ml403.h u-boot's config file to adapt it for my board and I have no problem to boot u-boot. I use the right board_info structure from <asm/ppcboot.h> and not the one in xilinx_ml403.h. When I load the zImage directly with xilinx xmd debugger, the kernel start without problem (if I don't have KGDB or SERIAL_TEXT_DEBUG option in my kernel config). But when I try to load the uImage with u-boot, the kernel start but crach befor I can see something on output. The kernel start because I debug it and the platform_init is ok, setup_arch too and it crach after ppc4xx_setup_arch at printk(KERN_INFO "Xilinx ML403 Reference System (Virtex-4 FX)\n") line when the kernel access in printk.c. I use the opb_uart16550 IP in my Xilinx design and the associat drivers in u-boot and linux. I'm new in linux embedded and I'm in internship...I have any idea where and what is the problem, certanly in the serial int I guest but I'm not sure. Thanks and sorry for my english I'm fench.
