Subject: [U-Boot-Users] Doubt on Kernel Linking
Date: Fri, 23 May 2003 19:22:40 -0700 [thread overview]
Message-ID: <00a901c3219b$59d821d0$6706a8c0@SPLENDOR> (raw)
In-Reply-To: 20030523120730.83A13C6162@atlas.denx.de
I kept the link address back at 0xc0000000.
Doing mkimage , I did load address and entry address as 0x0.
On my FADS823 board, I do a download to 0x100000.
And gave a bootm 0x100000.
But the system hangs after Uncompressing Kernel Image...
Note: I have compared the bd_info stricture of linux and u-boot . It is the
same . Also the IMMR address.
I do mkimage on gzipped binary image of vmlinux.
Please advice.
Rupesh
