hw.device-type: Modify bluechiptechnology-tm3 #398

Closed chrisruk closed 10 months ago

Change-type: patch

I found https://github.com/balena-io/contracts/blob/master/contracts/hw.device-type/rockpi-4b-rk3399/contract.json and https://docs.balena.io/learn/getting-started/rockpi-4b-rk3399/nodejs/ which appear to have the same installation process

Which I've adapted below -

Wait for writing of balenaOS to complete.
Remove the SD card from the host machine.
Insert the freshly flashed SD card into the TM3
Warning! This will also completely erase internal storage medium, so please make a backup first.
Connect power to the TM3
Wait for the TM3 to finish flashing and shutdown. Please wait until screen and Ethernet green LED are off.
Remove the SD card from the TM3.
Remove and re-connect power to the TM3 to boot the device.

I wasn't quite sure how the 'partials' maps to the above text though.

I'm just wondering also if I should change

    "storage": {
      "internal": true
    },
    "media": {
      "defaultBoot": "sdcard",
      "altBoot": ["internal"]
    },

To:

    "storage": {
      "internal": true
    },
    "media": {
      "defaultBoot": "internal",
      "altBoot": ["sdcard"]
    },

Originally I thought the first syntax was correct, as the TM3 boots from an SD card if one is inserted and otherwise boots from eMMC.

But now I'm thinking because we're using a 'flashing' image, we should use the latter syntax, as Balena will generally be run from eMMC?

Hi, yes, please make that change also
