Good question! I don't really have an answer. What I can say is that the next text output should be "FLASH: 64 MB". So I'm guessing something went wrong with your flash somehow. This could be a red-herring though. I would try the following before getting my hands really dirty:
* Changing the boot configuration to CONFIG C by toggling CONFIG DIP 1 and then power cycling * Updating the CPLD, via Xilinx JTAG, with the newest design (you can find it at casper_svn:roach/gw/binaries/roach_cpld/ * Try reinstalling uboot using the macG tool If these fail I would then try dumping the External Processor Bus memory using the maccraigor tool. * First try dumping some memory at the CPLD Base to check that the EPB is working You should get something like this... > halt > word 1c0000000 20 C0000000: 007F0200 31000000 05010000 05010000 C0000010: 01FF0000 03000000 D00D0800 06340100 C0000020: 007F0200 31000000 05010000 05010000 C0000030: 01FF0000 03000000 D00D0800 06340100 C0000040: 007F0200 31000000 05010000 05010 * Next try dumping the flash contents to check that flash is working You should get something like this... >word 1fffa0000 20 FFFA0000: 27051956 552D426F 6F742032 3030382E FFFA0010: 31302D73 766E3232 32362028 41756720 FFFA0020: 20372032 30303920 2D203136 3A30363A FFFA0030: 34342900 00000000 00000000 00000000 FFFA0040: 00000000 00000000 00000000 00000000 Next I would try loading uboot with the debug signatures enabled (see attached). If this fails I would use the debugger, or just lots of uboot debug messages, to find out where exactly the code got stuck. Please keep me posted on your progress. Good Luck, David
