Hello: I have sent this query to the u-boot list and did not receive a response - I am hoping that the linux/ppc list might be a more appropriate list for this question -
I apologize for the cross posting, however I am in real need of some direction Kindest Regards, Jerry Walden -----Original Message----- From: Jerry Walden [mailto:[EMAIL PROTECTED] Sent: Friday, March 21, 2003 3:12 PM To: U-Boot-Users at Lists. Sourceforge. Net Subject: start / load addresses for kernel Hello: I received the below advice recently: >since you are building for a non openbios kernel, you will need >to change the make file. The start/ load addresses and all are different I am trying to get more detail on what needs to change, I see 2 config options: 1) CONFIG_KERNEL_START_BOOL - is set this to yes 2) CONFIG_KERNEL_START -- what should this be set to - the default is 0xc0000000 seems fine to me Are there any other options that I am missing? Below is a log of my attempt to boot the kernel - displayed are the command line that is getting passed in, and well as the startup parameters - do these look okay - I made sure that the kernel bd_info struct is the same as the u-boot struct **************************************************************************** Script started on Fri Mar 21 14:43:27 2003 Welcome to minicom 1.83.1 U-Boot 0.2.0 (Mar 19 2003 - 12:09:59) CPU: IBM PowerPC 405GPr Rev.
