To do so I've dowloaded the ml403_emb_ref_ppc_81.zip from xilnx website as well as u-boot.zip (from ml410 documentation on xilinx web site). 1) First you I've modifie the xparameters.h file in u-boot/board/xilnx/ml403 directory to match hardware design of ml403_emb...81 design. (The memory mapping is different) I'm know have u-boot working on ML403 but the IIC EEPROM can(t be accessed. imd command (imd 50 10.2 10 )return error message, iprobe hang up and saveenv did not save anything into I2C memory. Does any one as any experience on that issue? To use I2C one should define either CONFIG_HARD_I2C or CONFIG_SOFT_I2C, but Xilinx as writen function (i2c_read...) in iic_addapter.c without using this macro. Is it the right way? 2) If I manually load kernel uImage in memory (fatload ace 0 400000 linux/uboot.uImage) and then boot the kernel (bootm 400000) then the process stop after Uncompressing Kernel Image ... Ok Note: The kernel has been compiled with a command line to boot via NFS. This image works properly if associated to bitsream in the ace file. The kernel 2.4.26 has bee patched for u-boot and recompiled with same config (using mkimage to generate uImage) Any suggestion? 3) The board did not start at powerup with that ace file (bitsream + uboot),the done light did not go on, I need to press sysace rst button to start properly. Does any one face that cold start prolblem? Thank in advance for any help Chris
