I thought those were the u-boot > locations for the mpc8349ITX (?). The ITX can boot from FE000000 or FEF00000 if you're using the latest code from denx.de. FE700000 is the address of the "alternate" U-Boot location. If you flip a jumper, addresses from FE000000-FE7F0000 are swapped with FE800000-FEFFFFFF. This causes the U-Boot that used to be at FE700000 to appear at FEF00000. Michael, I think your problem is in the configuration. For instance, you're building a U-Boot from the wrong config file, or you're flashing it to the wrong address, or there's some low-level config option that's set wrong, like a LAWAR or LAWBAR. I would use a BDI. You need to find out which instruction is causing the hang/panic. -- Timur Tabi Linux Kernel Developer @ Freescale
