Dear all: I have a problem with the Xilinx Spartan3E500 Rev.D starter kit and the Linux kernel 2.6.20-uc0 within petalinux-v0.20-rc3 . I used the reference design Xilinx-Spartan3E500-RevC-edk82 with ISE8.2 + sp3, and EDK 8.2 + sp2 . It seems a bit strange, because I'm not having any problems to compile and run the petalinux-v0.20-rc3 with the Linux 2.4.32-uc0 on my board. But something error when using kernel 2.6.20-uc0:
Found romfs @ 0x2220708c (0x00230000)petalinux-v0.20-rc3
