Torlando 2d26df32ff fix(nomadnet): partial refresh must not accumulate image records
Round-2 Greptile P1 (Partial Images Accumulate): the round-1 fix appended
fragment image records to the record list, so repeated refreshes of an
image-bearing partial re-appended on each pass and the list grew until
LIMIT_EXCEEDED permanently blocked that partial.

Correct semantics (reference 1.4.3: detect_images runs only at full page
load, never on partial refresh): copy the record list verbatim from the
base — same records, same order, same compact indices, constant count
across repeated refreshes. Fragment image blocks carry no record
(image_index -1) and render as alt-text placeholders until the next full
load, consistent with the loader being configured once per page.

Test: native partial-core check now requires a constant image count across
two refreshes and a placeholder fragment image; verified to fail against
the accumulation-buggy build.

Pyxis

An LXMF and LXST client firmware for T-Deck, built on a highly modified fork of microReticulum

Very much WIP, don't expect stability :)

Features

Reticulum transport over:

  • RNode-compatible LoRa
  • AutoInterface (local wifi)
  • TCP Client
  • BLE Interface (barely working if at all)

Other features:

  • GPS-synced time
  • One really annoying beep when you get a new message (user toggle)
  • View the announce stream
  • Choose a propagation node (and sync with it) (fixed in v0.2.1)
  • Set auto announce timer
  • Light up keyboard (user toggle)
  • Will crash in about 5 minutes of normal use (sorry) I had 5d uptime on v0.2.0 with BLE disabled
  • Make LXST voice calls (codec2 only, quality sounds horrible coming out the other end in Columba, needs work)

Flashing

The easiest way to get Pyxis running is the web flasher, which downloads release firmware from this repository's releases and verifies each image's SHA-256 digest against the release metadata.

For esptool (or any other tool that writes raw flash), each release also publishes a merged binary (pyxis-<tag>-merged.bin) that contains the bootloader, partition table, OTA selector, and application at their fixed offsets. Provision a T-Deck Plus (8 MB flash) with:

esptool.py --chip esp32s3 erase_flash
esptool.py --chip esp32s3 write_flash 0x0 pyxis-<tag>-merged.bin

Merged binaries are for first install / provisioning. Flashing one overwrites every flash region, including NVS (settings, identity) and the LittleFS partition (messages, paths, maps). To update an existing device without losing data, flash firmware.bin to 0x10000 only, or use the Columba-compatible pyxis-<tag>.pyxis.zip update package.

Why "Pyxis"

Pyxis, latin for "compass," is a constellation in the southern sky depicting a mariner's compass. Small but essential, the compass ensures every message finds its destination - even when the path is uncertain.
