Raspberry Pi CM5 images
Ready-to-flash OS images
Pre-configured OS images for the Raspberry Pi Compute Module 5. Flash to an SD card or eMMC, insert into the carrier board, and boot into a working grandmaster — Timebeat Agent, linuxptp and GNSS tooling pre-installed and tuned for the target hardware.
TimeBeat OS for Open Time Appliance / Open TimeCard
Raspberry Pi CM5 image — pre-configured for OTA and OTC hardware
A ready-to-flash OS image for the Raspberry Pi Compute Module 5 that ships pre-configured for the Open Time Appliance and Open TimeCard hardware. Boots into a working grandmaster configuration with the Timebeat Agent pre-installed and pre-tuned for the OTA/OTC carrier board.
▶What’s included (6 items)
- ·Timebeat Agent 2.3.5 (pre-configured)
- ·TimeBeat OTA/OTC device-tree overlays
- ·Auto-detect carrier board on first boot
- ·Pre-tuned kernel parameters for PTP performance
- ·SSH enabled (default: timebeat / timebeat — change on first login)
- ·Read-only root filesystem option for production
Based on Raspberry Pi OS Lite (Bookworm, 64-bit). Ships with the Timebeat Agent pre-configured and the TimeBeat OTA/OTC device-tree overlays, on a kernel pre-tuned for PTP performance. First boot auto-detects the carrier board and applies the PTP profile defaults, and SSH is enabled out of the box. The Agent handles GNSS, PTP and NTP directly, so no separate gpsd, linuxptp or chrony is required.
TimeBeat OS for Open TimeCard Mini
Raspberry Pi CM5 image — pre-configured for the OTC Mini carrier board
A ready-to-flash OS image for the Raspberry Pi Compute Module 5 designed specifically for the Open TimeCard Mini carrier board. Optimised for the Mini's compact form factor and power profile — boots into a working grandmaster with reduced memory footprint and power-aware defaults.
▶What’s included (7 items)
- ·Timebeat Agent 2.3.5 (pre-configured, low-memory mode)
- ·TimeBeat OTC Mini device-tree overlay
- ·Auto-configure on first boot
- ·Reduced memory footprint (~256 MB idle)
- ·Power-aware defaults for battery-backed deployments
- ·SSH enabled (default: timebeat / timebeat — change on first login)
- ·Read-only root filesystem option for production
Based on Raspberry Pi OS Lite (Bookworm, 64-bit). Ships with the Timebeat Agent pre-configured (low-memory mode) and the TimeBeat OTC Mini device-tree overlay, on a kernel pre-tuned for PTP performance with SSH enabled out of the box. Tuned for the Mini's reduced RAM (1-2 GB) and lower power budget. The Agent handles GNSS, PTP and NTP directly, so no separate gpsd, linuxptp or chrony is required.
