Hello
I am facing a problem with u-boot update
on my OMAP P2 730 target. Are there any build-time configruation options
for u-boot build related to the target's NAND or NOR flash. In other words,
do we need to specify any build-time configuration options if we intend
to burn the resulting u-boot binary to NAND or NOR flash.
I have U-boot 1.0.1 burnt to OMAP 730
P2 NOR flash. I am now trying to update u-boot using the method:
- Download u-boot.bin (new version)
to target's RAM using serial line
- Copy u-boot.bin to target's flash
using u-boot command 'cp.b'
The u-boot version I am running presently
is vendor supplied (version 1.0.1) and I want to update it with the one
I have built (version 1.1.1) for my target hardware.
I tried downloading the u-boot.bin to
the P2 730 RAM over serial line to a specific address and triggered the
binary's entry point using command:
go 'start address'
The new u-boot binary seems to execute
as it comes up with normal u-boot start-up messages, but stops and hangs
at a point. Please have a look at the traces of execution:
OMAP730 P2 # loadb 11080000
## Ready for binary (kermit) download
to 0x11080000 at 115200 bps...
## Total Size =
0x0001ca68 = 117352 Bytes
## Start Addr =
0x11080000
OMAP730 P2 # go 11080000
## Starting application at 0x11080000
...
U-Boot 1.1.1 (Apr 19 2006 - 15:50:59)
U-Boot code: 11080000 -> 1109CA68
BSS: -> 110A134C
RAM Configuration:
Bank #0: 10000000 32 MB
Flash: 0 kB
NAND:
--------->
The execution hangs at this point
I am not very sure what is expected
by u-boot binary at his point. The above binary is result of a custom build
done by me. The u-boot sources were downloaded from http://linux.omap.com
and the build time configuration was done using 'make omap730p2_config'.
Do I need to take care of any other
build-time options/configurations?
Kindly help if you have any ideas/answers.
Your suggestion on how to update u-boot
are also welcome.
Thanks
Chetan
