Finally Finished the project:

Serial terminal: Hazeltine Esprit (HL 1094)

Inputs Serial RS232 over DB25

Struggles:
Required special Terminal file in Terminfo

Parts:
-DB25 Male Header for breadboards
-Onion Omega2+
-Micro SD card
-PerfBoard
-Line Driver Max232CPE
-Vregulator LD33V (3.3v regualtor rated for 800ma)

By combining the Retro terminal project Ideas and the Debian Installation project. I have a system that can boot into debian via Chroot.

-Onion is setup with the Breadboard Breakout wings from OSHpark

Stealing a 5V tap from the keyboard decoder chip (pin 8 and 16). I can drop the 5V to 3.3v and power the onion.
If your onion crashes after flashing during boot. make sure you have the right Vregulator (LM33 won't do)

Set the environment to Export the TERM=hz1552
and SSH to any other host works like a charm, VI and Nano too

The only Drawback is being Chrooted to Debian, I can't set the Wifi with the wifisetup script.

@Arek-Z

there isnt any official boot loaders.

the closest I have gotten to no Onion OS's are Debian Mipsel (theres a guide on setting it up in a chroot)
https://community.onion.io/topic/2394/installing-debian-on-omega2-board

There is another guide on Installing FreeBSD on the omega , using Uboot and an LMZA image.

But other than that. its the stock Busyboxish openwrt . (which is good for getting Iot devices working)

I managed to disable the rc.d for mountd

this fixed the issue.

just a Heads up for anyone wondering whats going on with their cards auto mounting (when they setup a manual entry in fstab )

Hey Onion owners,

I have the Omega2p

I have been working on getting the debian chroot to work seamlessly as a login shell.
The issue so far is that the mount point for the chroot is not always ready via mountd (/var/run/mountd/mmcblk0p1)

In my fstab I have the initial mount of /dev/mmcblk0p1 /all auto 0 1

in my rc.local
I have mount binds to /all/sys for /sys , /all/dev /dev and /all/proc /proc

The issue is at some point the OS does a mountd (but not always at boot) and double mounts the card, confusing the Debian system regarding system calls to free and df.

how can I disable the mountd or is there a better way to approach this.
I am using debian since it offers the correct ncurses bins and tools i need.

my .profile in root spawns up the chroot for debian and it works rather wellish (though no login yet)

is there a good way to automate the process so debian boots up immediately?

I had a script that handled the mounting and the chrooting but the chrooting didnt take until after a login.
I had this run at rc.local

cat startup.sh
#!/bin/ash
/usr/sbin/swapon /dev/mmcblk0p2
/bin/mount --bind /dev /tmp/run/mountd/mmcblk0p1/dev
/bin/mount --bind /proc /tmp/run/mountd/mmcblk0p1/proc
/bin/mount --bind /sys /tmp/run/mountd/mmcblk0p1/sys
/usr/sbin/chroot /tmp/run/mountd/mmcblk0p1 /bin/bash

Hey Onioneers,

looking for a way to port the ncurses-bin package tools to this little device.

the basic ncurses package leaves out tic and other terminal database functions.
I saw debian has it as a mipsel .deb file. I tried making it as a .ipk (ar -x then tar ) but i got a "pkg_hash_fetch_best_installation_candidate: Packages for ncurses-bin found, but incompatible with the architectures configured. cannon install packages ncurses-bin

awesome project.

I have a similar journey ahead of me.

got the max232 chip setup . but needing the proper ncurses term library to work

Any clue on getting other terminals to work with it or profiles or is it all strictly vt100 compatibles

I require the hz1552 variant (interfacing a Hazeltine Esprit )

hello Onion ,

I have tried my attempt to get the cross compile environment setup,
Many guides etc.

I have the core compiled.

Under the make menuconfig , I was able to set that up and I even found that the libncurses6.0 was modularized. Instead I opted to enable the whole thing (even if I have to use a SD card )

So what is the process of getting a ipk file from this?

-I have made the changes in the make menuconfig
-ran make -j8
-I have my /source as /home/user/repo/source
-I see the build_dir/target-mipsel_24kc_musl-1.1.16

What is the next steps on getting this larger package version to the Onion.

I would love to see an example where someone took a linux package from sources and crosscompiled it instead of the simple C that we have as the example.

I Have Come up with an inittab solution :

I use a USB (until i setup a MAX232)

ttyUSB0::respawn:/bin/ash -l -c /bin/login

This will provide a basic login shell to the serial term and allow ssh to other systems.
It accepts CTRL+C too so pings work !!

@Leif-Bloomquist
I have the same setup in a way and I get a " -ash can't access tty; job control turned of "
When it shows on the serial port

I have this script work on rc.local and it works on boot.

Trying a ping command or top won't let me CTRL+C out of it.

for this project and initial stub work.

I began a similar project but without the max232 level shifter. It would explain why my terminal was receiving Garbage.

I encountered a odd sitiation with the script. If I use SSH to anther server , the password prompt returns on the omega putty shell and not the serial.

I also wasnt able to CTRL+C anfter a ping command.

ADDING More Info:

Adding a USB to Serial Device Worked ....

It registered as ttyUSBS0

I setup Minicom with 9600 8n1

And was able to Text to it

WTF

Update: THis works in Putty with Serial as USB-RS232 with the default settings :

9600 , D8 , no Flow control

For the life of me I ca'nt get it to work on Onion or Arduino ....

Hey Onioneers ,

I would like to connect this device to a serial console that operates at 9600 How would I go about setting this up and with the expansion Dock which ttySX is that one using ? ttys1 ?
