I have a few questions: 1. Does anyone have a patch for the mpc5121e for NAND booting where there is no NOR flash in the system? 2. Are there any patches that allow u-boot to be build in cygwin for a PPC target? 3. Has anyone used CodeSourcery's PPC tool chain with u-boot? 4. Has anyone implemented/used DFU mode with the mpc5121e? Thanks! Jeff Smith Sandel Avionics, Inc.
