I have a 405GP kernel loading great on the Walnut board using the IBM serial monitor and treeboot, but I'm unsure what I need to do on the CR before I can begin successfully running Linux on it. I am using an Abatron BDI2000 along with GDB to load code and tweak registers on the target. Right now, I am configuring the SDRAM controller and UART0, but apparently that is not sufficient to fully boot Linux, since I never get any output on the serial port except for the 'a' debug printout I enabled in head_4xx.S Does anyone have a minimal 405GP/CR bootloader that I could use as an example? Or perhaps a FAQ on how to bring up a deeply embedded 405 using the Abatron box? Thanks, Bryan Rittmeyer -- Bryan Rittmeyer mailto:bryan@ixiacom.com Ixia Communications 26601 W. Agoura Rd.
