Writing to the fpga from the gumstix through the gpmc : first success !

Today we succeed in sending a data in the gpmc bus that we have read with the fpga and sent to the ram. In the 16 bits, one was false, so we still have some signal issue but it’s already a good news !

    Yes actually the 10th bit was wrong.
    Now I tried to send the opposite of the message later sent, and I received the good answer excepting the bit number 7 and 8. Let’s investigate!

    14 bits ought to be enough for everybody.

    Our investigation was successful: some pin of the FPGA was not fully soldered.
    Now let’s implement and test a read function from the fpga to the gumstix.
