My sincerest apologies to Freescale. Upon further research, it appears that it was another TimeSys engineer (who has since moved on to another job) who built and installed U-Boot on our MPC885ADS board. Strangely, it appears that he started with the community U-Boot 1.1.3 and then added a patch to change the IMMR value (plus a few other things). I'm not sure why. He's a very bright guy, so I'm very puzzled.... Anyway, mystery solved. Again, my sincerest apologies to Freescale. I built the community U-Boot 1.1.4 and flashed it onto our board. Linux 2.6.16.11 now boots much farther than before (I'm now getting printk() output). The kernel is hitting a new problem now, but I suspect it may be related to the TLB code that Marcello has discussed recently. I'm going to go look at that patch next. :-) > Thanks. > > -- Dan Thanks again to everyone!!! Walt Wimer TimeSys Corporation
