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?
