Flashing

NOTE: During configuration or flashing a device, the only things that should be hooked to the device is the computer and power.

Flashing OpenWrt

On the OpenWrt ToH (techdata entry)
On the OpenWrt Wiki
OpenWrt Target: ipq40xx
OpenWrt Subtarget: generic
OpenWrt Package architecture: arm_cortex-a7_neon-vfpv4
Support started version: 23.05.0
Current supported version: 23.05.5

There does not appear to be a way to trigger TFTP recovery without entering U-Boot. The device must be opened to access the serial console in order to first flash OpenWrt onto a device from factory.

The device has automatic recovery backed by a second set of partitions on the larger of the two SPI flash ICs. Both the primary and secondary must be flashed to prevent accidental rollback to "factory" after 3 failed boot attempts.

Serial console

A serial console is available on the following pins of the populated J2 connector on the device mainboard (115200 8n1).

(<-- Top of PCB / Device)

 J2
 [o o o o o o]
      |   | |
      |   |  `-- GND
      |    `---- TX
      `--------- RX

Installation instructions

1. Setup TFTP server with server IP set to 192.168.1.236. 2. Copy compiled `...squashfs-factory.bin` to `nodes-jr.img` in tftp root. 3. Connect to console using pinout detailed in the serial console section. 4. Power on device and press enter when prompted to drop into U-Boot. 5. Flash first partition device via `run flashimg`. 6. Once complete, reset device and allow to power up completely. 7. Once comfortable with device upgrade reboot and drop back into U-Boot. 8. Flash the second partition (recovery) via `run flashimg2`.

Revert to "factory"

1. Download latest firmware update from vendor support site. 2. Copy extracted `.img` file to `nodes-jr.img` in tftp root. 3. Connect to console using pinout detailed in the serial console section. 4. Power on device and press enter when prompted to drop into U-Boot. 5. Flash first partition device via `run flashimg`. 6. Once complete, reset device and allow to power up completely. 7. Once comfortable with device upgrade reboot and drop back into U-Boot. 8. Flash the second partition (recovery) via `run flashimg2`.
