Hi
Thanks for your reply. U-boot is working very well on the custom mpc8245 board. I did some changes in the A3000.h file to make it work. All most all the features of u-boot are working. Problem comes when I load linux on to it. I compiled ELDK 3.0 verison. Since ELDK 3.0 does not have A3000 configuration I modified Sandpoint8245 configuration and compiled it. As I mentioned I did all the 3 steps mentioned in FAQ for "linux hangs after uncompressing" problem.
1. I configured linux kernel Sandpoint8245 .config file with flash and network drivers needed for my board. Is there any thing I need to do for SDRAM? 2. When I tried to run vmlinux using BDI2000 (with out u-boot) I got the following output
BDI>prog 0xffc00000 vmlinux.eldk bin Programming vmlinux.eldk , please wait .... Programming flash passed BDI>go 0xffc00000 - TARGET: target has entered debug mode BDI>info Target CPU : MPC82xx (G2H4) Target state : debug mode Debug entry cause : FPU unavailable exception Current PC : 0x00000000 Current CR : 0x20000000 Current MSR : 0x00000000 Current LR : 0xffd7ee18
Is there any thing I need to do to fix this.
3. Is there any embedded linux available for the artis A3000 type of board?
Thanks Kishore

I am trying to run Embedded linux (ELDK) 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
I don't think that you compiled the _ELDK_!
linux hangs after uncompressing
...
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.
I hope with "used" you mean that you made sure it is NOT set.
Could you please let me know what should I do next?
You make a fundamental error. You're using an U-Boot configuration which has not been correctly ported and configured to your board, and you're using a Linux kernel which has not been correctly ported and configured to your board.
This cannot work. Go back to square 1.
Best regards,
