Subject: [U-Boot] Porting u-boot to new PPC440EP board
Date: Fri, 3 Jul 2009 11:26:22 +0800 (CST) [thread overview]
Message-ID: <2628639.181881246591582091.JavaMail.coremail@bj126app63.126.com> (raw)
Hi,
I use a new board designing based on PPC440EP evaluating board, called yosemite.
I use u-boot version 1.3.1.
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.
Would you like tell me how did you solve the problem , or how can I completely porting u-boot to the
new board.
Best regards,
Yangguang
