Subject: [U-Boot-Users] MPC8245 custom board, Linux kernel hangs after uncompressing
Date: Tue, 19 Apr 2005 16:46:58 -0700 [thread overview]
Message-ID: <2cf2641f0504191646536d2ad5@mail.gmail.com> (raw)
Hi
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
linux hangs after uncompressing

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
