pandaboard ES Ver.B3 Long packet

Hello,

DSI's long packet has 65541 bytes,

But I send a long packet with 5800 bytes.

Minicom said, my packet is too long.

How many is the maximum number of long packet?

    Hi Yuan-Heng,

    Is this the message you are observing? 

    if (dsi->vc[channel].tx_fifo_size * 32 * 4 < len + 4) {

                   DSSERR("unable to send long packet: packet too long.\n");

                  return -EINVAL;

           }

    You must check the size of your buffer also. It might be  because it is limited to specific threshold. If that is the case I suggest you increase it.

    Regards,

    Boyko

    I declare "int length=0; " and add source code "length=vc[channel].tx_fifo_size * 32 * 4 ; ".
    But compiling , I have a error. What error happen ? Is datatype not match ?
