I use a new board designing based on PPC440EP evaluating board, called yosemite. I use u-boot version 1.3.1.
1.3.1 is quite old. I strongly suggest that you update to a recent version.
I reduce the SDRAM and Flash size to 128M and 16M, I do the porting works as decribed in th maillist"new board SDRAM conf",which you posted in last year. http://lists.denx.de/pipermail/u-boot/2008-November/042924.html and now face the same problem when u-boot run to trap_init, and get the same error message. When I add blr instruction to the trap_init function, it return but hang befor main loop.
You can't just exit the trap. You need to solve the problem that issuing the trap before you can really proceed further.
Would you like tell me how did you solve the problem , or how can I completely porting u-boot to the new board.
This could have several reasons. One is incorrect SDRAM setup. Other are possible as well. Not sure what's going on here.
