Hello, I'm afraid this question is a bit off-topic because it has perhaps more to do with hardware than software but I don't know of a better place to ask this sort of question.
Has anyone had experience adding memory (specifically SDRAM) to a carrier board for TQM855 or other TQM mini-modules ? It seems like this should work except for : 1) The 50 pF capacitance limit on the MPC8xx bus lines (ie. how much is already used on the module ?) 2) As far as I can tell it should be possible to use UPMB to control the new memory bank without interfering in any way with the UPMA configuration. It appears that UPMB is only used by ppcboot for the CAN driver (which I'm not using). Is this correct ? 3) Should it be possible to configure the extra memory bank after ppcboot has started, say with an independant program which runs before the kernel ? Any advice would be appreciated.
