track3r-os v1.0.1: release notes

v1.0.1 fixes the pads on later Trackers. Everything else is v1.0.0. The full list of changes is in the changelog; the v1.0.0 notes are in v1.0.0.md.

track3r-os is community firmware for the Polyend Tracker. It is unofficial and not affiliated with Polyend. Installing it replaces the firmware in your unit. It is licensed GPL-3.0-or-later. Third-party licences are in THIRD_PARTY.md.

Back up your SD card and keep the official firmware file before you install.

What is fixed

• The pads did not answer on later Trackers (plastic back, boards Control 4.0 / Grid 2.0; issue #1). The unit started, the buttons and the screen worked, the status LED flashed 13 times at power-on and the pad grid stayed dark and dead. The pad board is now started later and more gently, and its chips are asked again until they answer. A user with an affected unit confirmed that the pads and note entry work. On first-batch units (metal back) nothing changes.

Files

• track3r-os-v1.0.1.ptf, the update file. For a first install from the official firmware you rename your copy on the card (see Install).
• SHA256SUMS, the checksum of the .ptf.

SHA-256 of the .ptf: bc1cf7b8ca02d5b5f9f8e4abffe2d5b9f6943fe6a3ba1ad94bd26a5ff775e2de

Check your download with sha256sum -c SHA256SUMS.

The app modules are the same as for v1.0.0: the release apps-v1.0.0 on the Releases page.

Install or update

• From track3r-os v1.0.0: copy track3r-os-v1.0.1.ptf into Firmware/ on the card, put the card in the unit, open Config, INFO and press F8 (UPDATE). Or install it as below.
• From the official firmware, or when the pads are dead (v1.0.0 on a later unit):
  1. Copy everything on the SD card to your computer.
  2. Copy track3r-os-v1.0.1.ptf into Firmware/ and rename the copy to PolyendTracker_0.0.1.ptf. It must be the only .ptf there. Do not use the Polyend Tool app.
  3. Use the hidden reset button, as in Polyend's emergency flashing page.
  4. After the restart, open Config, INFO. BUILD ID should show v1.0.1.

The full steps and the way back to the official firmware are in the installing guide.

Known issues

The known issues of v1.0.0 stay, except the pads:

• Swapping the SD card can crash the unit. Switch the unit off before you change the card.
• Very heavy projects can exceed the CPU budget; some Perform effects cost CPU while held. See the CPU budget.
• The update list on the unit shows only the first 12 files of Firmware/. Keep 12 or fewer files there.

Not yet verified

• The pads on other later board revisions: one unit has been reported working.
• The items listed as not yet verified in the v1.0.0 notes.
