Hi I am trying to run Embedded linux (ELDK) (2.4 kerenl) on a custom powerpc board, which is similar to Artis A3000 board. This board has mpc8245(XPC8245LZY266B), natsemi 83815 ethernet, 4MB intel e28f320 flash, 16MB winbond w986432DH-6 SDRAM. So I configured and compiled U-boot for A3000 borad. U-boot worked on my board also. Next I compiled ELDK 3.0 for Sandpoint 8245 board and copied to flash. But linux hangs after uncompressing

OK Uncompressing Kernel Image ... OK nothing happens after this until I reboot the board. I read u-boot FAQ and configured bd_info structure same for both u-boot and Linux. I found that CFG_IMMR is not applicable to MPC8245. I also used clocks_in_mhz variable also before loading Linux. I am stuck here. Could you please let me know what should I do next? Thanks Kishore
