Which version of PPCBoot? The official releases (1.1.5) should work just fine; they do so on several tested systems. If you're using the top of tree on the CVS server (i. e. the version which includes the "Grand Unifying I2C interface patch") you may have to adjust a couple of things; this is not that well tested / working yet. > Using no microcode patch, and DPRAM allocation. I wonder why you use the CPM code at all. I always found it much easier to use CONFIG_SOFT_I2C ... > DPRAM allocation pointed out a bug so I guess it's not that well tested yet > :( . > Trying fixed DPRAM offsets and microcode now...
