in MPC5777C snooping mode do not work with EBI set to demultiplexed 16-bit bus? I tried it with 32 bit bus multiplexed and it works.
I am not sure if I understand the question. The term "snooping" ca have something to do JTAG or coherency unit. But how it is related to EBI module? Could you please clarify your question? Thanks
when I use the memory coherence unit to synchronize the two cores, usually called snooping mode, actually the mechanism does not always work properly. This operation is performed in external memory on 16-bit EBI
I am sorry, I have completely forgotten on this thread.
Could you give me as much details as possible? Source codes (EBI settings, cache and coherency unit), maybe schematic of connection. When the problem happen and how it manifest? Thanks
I will prepare some documentation and C example.the card is the same where improperly does the burst on external memory, but by mounting the MPC5674, the burst goes.
so i think that isn't a HW problemthe card works properly if you do not use the burst, The cache worksThe card is already in production, but we do not use burst and second core
