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
