install-forgefirm.sh completed silently broken when the download, flash write, mount or uEnv rewrite failed - add die() checks around every critical step (audit N13/M12) and download the release asset under the exact Scarthgap artifact name (forgefirm-image-glowforge.rootfs.wic.gz) so uploads need no renaming. ffboot no longer depends on the never- provisioned /etc/fw_env_mmcblk2.config: it falls back to /etc/fw_env.config (which both the factory and ForgeFIRM images ship, pointing at the eMMC env) and checks fw_setenv results (audit N16). BUILD.md gets the real artifact name and marks the built u-boot reference-only; INSTALL.md drops the stale script/ogboot names and the cloud-connect promise, stating the image is bring-up-only (audit N11).

# Dual Booting OpenGlow and Glowforge Factory Firmware
|
|
OpenGlow firmware for Glowforge brand CNC lasers can be installed along side the factory firmware using the on-board flash storage. This has the advantage of not requiring you to solder on an external SDCARD holder.
|
|
|
|
The factory flash is a 4GB eMMC. The factory firmware resides on two partitions that are 200MB each, and has a non-volatile (survives firmware updates) ```/data``` partition of ~3GB. All that is stored on the ```/data``` partition is configuration files and log files.
|
|
|
|
We can resize the ```/data``` partition down to 2GB, leaving a ~1GB partition for us to install OpenGlow on.
|
|
|
|
## Prerequisites
|
|
Before getting started, you will need [serial console](https://github.com/ScottW514/forgefirm/blob/master/SERIAL.md) access to your Glowforge. If you do not have a unit with the factory installed, you will need to install your own.
|
|
|
|
You should also have followed the initial Glowforge [setup instructions](https://glowforge.com/support/topic/unboxing-setting-up/unboxing-and-setting-up-your-glowforge), and have your unit connected to your wireless network.
|
|
|
|
## Installation
|
|
Connect to the console port (or plug in your wired adapter) and fire up your Glowforge. When you reach the logon prompt, enter ```root``` for the username. No password is necessary.
|
|
|
|
|
|
|
|
### Stage 1
|
|
We'll need to remount the root partition as read/write, and download and run the [installation script](https://github.com/ScottW514/forgefirm/blob/master/scripts/install-forgefirm.sh) by entering the following commands:
|
|
```bash
|
|
mount -o remount,rw /
|
|
curl -L https://raw.githubusercontent.com/ScottW514/forgefirm/master/scripts/install-forgefirm.sh --output ./install-forgefirm.sh
|
|
chmod +x install-forgefirm.sh
|
|
./install-forgefirm.sh
|
|
```
|
|
|
|
This will fire up the installation script, and present you with **a very important warning**:
|
|
|
|
|
|
|
|
**---Dramatic Pause---**
|
|
|
|
**Did you read that? Yes? I'll repeat, just in case - This is experimental software. Use of this software could seriously maim or kill you or others. Use at your own risk!**
|
|
|
|
If you are bold, type ```y``` and hit ```enter```.
|
|
|
|
From there, the script will automagically do the following:
|
|
|
|
* Stop all Glowforge services
|
|
* Back up critical data from the ```/data``` partition. This does not include log files, but you probably don't care about those anyway...
|
|
* Rewrite the flash partition table. This shrinks the ```/data``` partition from 3GB to 2GB, and creates a new 1GB partition for OpenGlow to live on.
|
|
|
|
After these steps have completed, you will be prompted to reboot:
|
|
|
|
|
|
|
|
### Stage 2
|
|
After the device reboots, login as root and run the script again:
|
|
```bash
|
|
./install-forgefirm.sh
|
|
```
|
|
|
|
This will complete the installation process by performing the following steps:
|
|
* Stopping all Glowforge services
|
|
* Restoring the critical ```/data``` files
|
|
* Restarting the network services.
|
|
* Downloads the [latest OpenGlow image](https://github.com/ScottW514/forgefirm/releases) from GitHub.
|
|
* Writes the OpenGlow image to the flash (this takes a bit, be patient)
|
|
* Installs the ```/data/ffboot``` utility so you can switch between ForgeFIRM and factory images.
|
|
|
|
Hit any key to reboot into your fancy new OpenGlow image.
|
|
|
|
|
|
|
|
### Welcome to OpenGlow!
|
|
|
|
|
|
|
|
Login is ```root```, no password. You can also connect via SSH - same user, no password (obviously, you should change this).
|
|
|
|
> **Current status: this image is bring-up-only.** No controller or cloud
|
|
> client starts at boot — the machine boots to an idle shell with the kernel
|
|
> driver, hardware libraries (gfhardware/gfutilities), and camera tooling
|
|
> installed. The grblHAL controller (forgectrl) is under development; the
|
|
> legacy cloud client (gfui-client) is deliberately not shipped. Nothing
|
|
> homes, moves, or connects anywhere until you start it yourself.
|
|
|
|
You can easily switch back and forth between factory and OpenGlow images:
|
|
```bash
|
|
# To switch to the factory image run:
|
|
/data/ffboot -e
|
|
# To switch to the OpenGlow image, run:
|
|
/data/ffboot -e4
|
|
# If you added the SDCARD, you can boot from that with:
|
|
/data/ffboot -s
|
|
```
|
|
|
|
**NOTE:**
|
|
This firmware is in beta. It mostly works. It is for experimentation purposes - not for production. Expect problems.
