when i enable the original dtb file, the board is now working, I am however succeeded in soldering a serial connection to the board. The only strange thing is when i send from one side: echo -en '\x00' > /dev/ttyS0 i receive 0x00 in hex echo -en '\x01' > /dev/ttyS0 i receive 0x7F in hex --> this makes the serial output unreadable since the mapping of characters seems to be off, does anyone has an idea how to fix this? --> i tried this with a baudrate of 300 to be sure the connection is stable. --> i tried to attach my serial output to the input of the pc and that return fine, so it seems the 2 serial ports are actually speaking another dialect. > _______________________________________________ > arm mailing list -- arm@lists.fedoraproject.org > To unsubscribe send an email to arm-le...@lists.fedoraproject.org _______________________________________________ arm mailing list -- arm@lists.fedoraproject.org To unsubscribe send an email to arm-le...@lists.fedoraproject.org
