The configuration file has some macros for setting +the clock speed, not all have been tested. They all have +a 10MHz input clock. Please do not check in a configuration +file that selects a high speed not available on all processors. +We chose the 66MHz core and bus speed, which should be OK on +all boards. If you have a processor, lucky you! :-) +Just build a new configuration with that speed, check +the macro configuration to ensure it's correct. If the +macro is updated, please check that in, but keep default +processor speed. + +The board is likely to have more than 1Mbyte of NOR boot flash. +It was also configured with a high boot vector (Dan's fault) +so the standard 8xx mapping doesn't work well. We had to move +the addresses around a little bit so one copy would work. The +flash got fragmented, and we are working on a better solution. +There is an "xtc.cfg" floating around for the BDI2000, use +that for programming a new version of U-Boot. You can probably +find it on the Silicon Turnkey eXpress (www.silicontkx.com), +Embedded Alley Solutions (embeddedalley.com), or Denx (denx.de) +servers. + +The board will also have various SDRAM sizes, but the code +should automatically determine the amount of memory. + +There are a couple of different board versions, visually +they use different BGA or surface mount memory parts. However, +they are logically the same board. + +Now, some operational notes. + +The board has the option of sporting two FEC Ethernet ports. +The second port isn't configured to be automatically available +because it would cause U-Boot to generate a board data structure +(the bd_t) with multiple MAC addresses and be incompatible with +standard 8xx kernel builds. You can use/test the second FEC +in U-Boot by assigning an 'eth1addr' and selecting the second +FEC as the port to use. + +Since this is just a development board and not a product, STx +does not assign unique MAC addresses. We just pilfer the +"default" ones used by Wolfgang on some other boards. Please +ensure you assign unique MAC addresses when using these boards. + +The serial port baud rate is 38400, because that's the way +I like it :-) + +Thanks to Pantelis for lots of the work on this board port. + +Have Fun! + + -- Dan + +15 August 2005 |
