Hi Chris, Many thanks for that. However I only have a uImage in my build, no zImage so can't do a diff to find the offset, is there another way to find that out? Maybe you or someone else knows what script in openembedded calls the mkimage utility so I can find what parameters are passed ..
By the way, I set UBOOT_LOADADDRESS and UBOOT_ENTRYPOINT to be the same (0x80400000, a bit past u-boot and the environment) in my config file, I am not sure if the entry point should be the same as the load address.

Hi Bernie, I've experienced this before when the UBOOT_LOADADDRESS and UBOOT_ENTRYPOINT values in the machine config file for OpenEmbedded aren't properly set to the correct value. You may want to double check those values. Also, try setting your bootm address just a tag higher in memory than the actual UBOOT_ENTRYPOINT. I forgot what the exact uboot-mkimage header put on the uImage is, but you can do a hex diff between the zImage and uImage files to figure it out. That offset can sometimes cause some odd booting problems. So if your ENTRYPOINT is 0x8300000 and the uboot-mkimage offset is 0xC0, for example, you'd need to bootm 0x83000C0. (Again, double check the uboot-mkimage offset.) Good luck, Chris _______________________________________________ Openembedded-devel mailing list [email protected] http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-devel _______________________________________________ Openembedded-devel mailing list [email protected] http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-devel
