 Posted: Tue Jul 04, 2017 9:05 pm Post subject: Connecting a Pi to Gentoo using an Adafruit 954 cable |
 |
|
I've bought an Adafruit 954 USB-TTL cable to connect my raspberry pi to my laptop. I followed the adafruit Lesson on how to activate support for it on the Pi (Still running Rasbian Jesse for the moment). The problem I'm having is that I haven't figured out how to connect from my computer running Gentoo to the RPi using the serial cable.
When I connect the serial cable to the computer it appears to be recognized correctly:
| Code: | silverfish /home/anon # tail /var/log/messages
{SNIP}

The adafruit instructions suggest that the next step would be to connect to the TTY using a terminal program. Screen is suggested:
| Code: | silverfish /home/anon # screen /dev/ttyUSB0 115200
/tmp/screen/S-root/3653.pts-0.silverfish: connect: No such file or directory
|
Gentoo apparently doesn't have the same TTY device names as whatever distribution Simon Monk and lady ada were using.
In /dev/ there are a lot of TTY devices:
| Code: | silverfish /home/anon # ls /dev
autofs hidraw0 mapper nbd6 sda2 tty15 tty31 tty48 tty7 vcs7
block hidraw1 mcelog nbd7 sda3 tty16 tty32 tty49 tty8 vcs8

But I don't know if any of these will help me connect to the Serial Console Cable.
According to the tutorial: | Quote: | | Linux Kernels 2.4.31 and above already have the PL2303 and CP210X USB driver for the Console Lead built-in, so you should not need to install that. |
Because I've compiled my own Kernel on Gentoo I wonder if I left out something that is required to support this device; but I haven't figured out what yet.
Ideas? |

Aries97,
That's the prolific device. I have one of those.
| Code: | $ grep 2303 /usr/src/linux/.config
CONFIG_USB_SERIAL_PL2303=m |
