It should also +work on MVME230x where x is 1, 2, 3, or 4 which is the same board +using a '603 instead of a '604 processor. RTEMS_CPU_MODEL would +need to change in make/custom/mvme2307.cfg. + +Application is linked to run from RAM. If running from ROM, it +will copy itself to RAM (0x4000) when it boots. PPCBUG should +be used to load a binary image from the TFTP host into location +0x4000, with an entry point at 0x401c. PPCBUG can be set to +autoboot the application from ROM. PPCBUG does all of the low +level setup of memory controllers and such on the board before +jumping into the RTEMS application. + +TODO: Data cache is not enabled. This BSP should probably +be part of the MCP750 BSP as much of the hardware here is +also on the MCP750 board. The dec21140 driver here is derived +from an early version from the MCP750 BSP, but has been +rewritten to use scatter/gather DMA and interrupts rather than +CPU copies and polling. This should be considered for merging +into to the MCP750 BSP. The interrupt conroller code needs to +be better integrated into RTEMS calls like the MCP750. The +BSP should probably be renamed to mvme230x. + +---------------------------------------------------------------------------- + +Building and loading an application: + +=============== (host) ======================================= +% make +% powerpc-rtems-objcopy --output-target=binary hello.exe /tftpboot/hello.bin + +=============== (target - run from RAM) ====================== +PPC1-Bug>niop +Controller LUN =00?
