Hi, A customer of mine is Petalinux and has some DDR connected
to the system. When the cache is 8K all accesses to memory appear to be fine. When the cache is lowered to 4K (to save on BRAMs required
elsewhere) they find that the memory accesses get corrupted. While I know “corrupted” doesn’t say much
I myself have not investigated in depth how or in what form the corruption
presents itself, however, I wanted to find out whether there were any known
issues with using cache sizes of less than 8K with Petalinux exist or if
anybody had seen similar things happen? As far as I can tell there should be no issue here. The target device is a XC3S1600E for reference. Thanks, Stephan |
