I would like to configure an FPGA from and iMX6 using a configuration stored in SDRAM. To do this I need to write 8bit data to a bus and strobe a 100MHz clk signal as I go. Is there a peripheral that could help me ship out 8-bit data to an external bus, preferably using DMA? I assume that the EIM is my best bet, but I am already using the EIM with said FPGA for another interface and would like to avoid the complexity. I can still use EMI, but it seems risky. I have looked through the data sheet but thought I would ask here in case there is a clever way to do it that I am missing. Any ideas?
You may try using i.MX6 IPU display interface in asynchronous mode (system-80 interface), which is similar
to the EIM.
