I had the same issue with minicom not taking my keystrokes. You have to make sure the minicom setup is correct. You can get complete instructions at the URL below, or see partial instructions I've posting below that. After following these, minicom works correctly. I think the key for me was turning off hardware flow control.

You will also want to change any other settings appropriate for your board such as disabling hardware flow control, a typical setup for a Davinci/OMAP EVM should look like the following. +-----------------------------------------------------------------------+ | A - Serial Device : /dev/ttyS0 | | B - Lockfile Location : /var/lock | | C - Callin Program : | | D - Callout Program : | | E - Bps/Par/Bits : 115200 8N1 | | F - Hardware Flow Control : No | | G - Software Flow Control : No | | | | Change which setting? | +-----------------------------------------------------------------------+ In the serial port setup, choose the right setting for the serial device. Press ‘A’ to navigate to the Serial Device setup, then edit the /dev/ttyXXX to reflect your current system setup. If you are using a USB-to-serial converter, your serial device probably /dev/ttyUSB0. Do a ‘lsusb’ and ‘dmesg | grep usb’ to find out. - Next, press ‘E’ to navigate to Bps/Par/Bits. This is the bit rate, parity and stop-bit setting, set it to 115200 8 N 1 - Then, press ‘F’ and set the Hardware Flow Control to No and then press ‘G’ and set the Software Flow Control to No -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
