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
