I have a Xilinx evaluation board ML507 Virtix-5. I loaded u-boot version 1.3.4 on the NOR flash and I am running uboot out of NOR flash. Uboot comes up ok and it seems to be good. Then using Montavista 5.0.24 distribution I builded an uImage (make uImage) for the ml507. I have also builded a filesystem for it. I burned both the uImage and the filesystem in the NOR flash. Then I run uboot from reset, uboot recognizes the uImage and unzips it corectly, no erros from uboot, but when uboot jumps to run the kernel, there is no response on the serial port. Not even the linux banner gets printed. It looks that the kernel is just not running or crashed. Did anybody try this?
Also does xilinx have a working linux source tree for the ML507 Virtix-5 evaluation platform and an executable that I can try. And can you point a link to it if available.
