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 |
