That is as expected. > On the one I am trying to build, when it goes crazy, I see both the > RX and TX either flashing at the same time or alternating (at > 115200 it is really too fast to tell for sure). I think if the Rx LED is flashing, your terminal program is sending characters. If there was some sort of short between the Rx/Tx lines, at the serial UART level (ie: the SoC pins), you wouldn't see the Rx light from the FTDI chip. ...so it sounds like you have something messed up in your custom uSD setup. I would recommend trying to replace one bit at a time (Root OS, Linux Kernel, U-Boot boot-loader) from a known good working uSD image. -- Charles Steinkuehler [email protected] -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
