Re: hang up after kernel start

Did you disable the MMU in the bootloader before jumping to CE? Is all KMode set? Better to show us your sysgen'ed ce.bib memory and config section so we know what's actually been set.

BTW: Any specific reason why you leave a gap between space for NK and RAM (iow, why not set the NK length to 2ED0000 or lower the RAM start address and increasing the RAM length)?

here hang up<<<<<<<<<<<

The boot loader successfully jumps to correct physical launch address. After Jump to the physical launch address, LED can glow before the kernelstart call. i think that Some where hang up in the kernelstart. Please give me a guidance to solve this problem and how to debug the kernelstart functions.
here i have enclosed startup.s, config.bib, oaladdress table.
