Minicom status is shown as offline and no action is happening on the key presses.
Minicom is setup as described in http://processors.wiki.ti.com/index.php ... _in_Ubuntu for serial device /dev/ttyAMA0 (Bps/Par/Bits - 9600 8N1, Hardware and Software Flow Control set to "No")
For troubleshooting to ensure that there are no hardware issues (I tried with two different Pi3 also) with the MAX3232 adapter or the Pi3 itself, I tried to connect the UART TXD and RXD pins - 8 & 10 and was trying minicom again on the Pi.
minicom -b 9600 -D /dev/ttyAMA0, but the results are the same.
Following the posts on this forum, I had made sure the following:
1. Disabled the serial console, using "sudo raspi-config", set enable_uart=1 in /boot/config.txt
2. Disabled the login prompt by disabling the serial getty service
Code: Select all
sudo systemctl stop serial-getty@ttyAMA0.service sudo systemctl disable serial-getty@ttyAMA0.service
