Problem: The time required to read data from either SDR or DDR SDRAM using the LCD DMA controller takes longer than expected. ... **** Does anybody know whether LCD with greater resolution then QVGA will definitely not work? (I'll use 480x272 24Bit) Or is there something I could fine tune in memory arbiter? Has somebody a lager LCD than QVGA running on Linux with this SOC? Thanks in advance Stefan
