    ports:

EM6330

I have an EM6330 camera. I want to run my own software on it. It's based on the hi3518 Chip, and uses a ARM5 EABI arch. It runs a faily old kernel:

# uname -a
Linux IPCamera 3.4.35 #58 Mon Nov 27 12:35:06 CST 2017 armv5tejl GNU/Linux

There's a NAND that gets mounted on /mnt/mtd and a memory filesystem of 10MB that gets mounted on /mnt/mtd/ipc/tpmfs. There's also a SD card slot, which gets automatically formatted with a FAT32 partition with the type set to Linux (yes, not DOS). The auto-mounting is done by a shell script that runs in the background, so if you want to handle it yourself, just kill that.

Notes for installing proxmox/maas/juju/k8s onto a PC

Adapted from https://github.com/antongisli/maas-baremetal-k8s-tutorial/blob/main/maas-setup.sh

Network setup:

• vlan 201 for mgmt (maas, juju), has internet through the router on 10.0.201.1
• default vlan for other traffic
• maas lives on 10.0.201.2 in vlan 201, and on an IP in the default VLAN (web ui)

Install proxmox

• just the defaults

# This is a 'dumb' script to convert the Victron modbus excel sheet to home assistant sensors.
# https://www.victronenergy.com/upload/documents/CCGX-Modbus-TCP-register-list-3.60.xlsx
# It just 'walks' over all IDs in the sheet, and probes your GX device on `IP`, to see if it generates data or an error
# If there's data, it will add it to the sensors.
# This does create some duplicate names as some descriptions are duplicated in the sheet, so check it afterwards.
