The Simplexity team can be as involved in the production phase as requested by our clients. For clients with internal manufacturing or established relationships with contract manufacturers, our engineers are available to ensure quality is maintained and provide ongoing engineering support as needed.

Simplexity has a dedicated New Product Introduction (NPI) team that can guide the transition from design into production. The NPI team presents multiple options for manufacturing to the client, allowing clients to choose the solution that best suits their needs. This can involve Simplexity performing initial builds in-house prior to full handoff to a contract manufacturer or building the product via established relationships with contract manufacturing partners either domestically or overseas early in the process.

Typical deliverables:

Manufacturing guidance and ongoing engineering support
Ongoing quality metrics monitoring and optimization

Some LibreTech boards have an SPI flash chip separate from the eMMC. Storing U-Boot on SPI allows you to boot from external USB drives or network (PXE) without touching the eMMC OS.

To flash U-Boot to SPI using the libretech-flash-tool:

# Build U-Boot for your specific board
make -C u-boot/ libretech_cc_defconfig
make -C u-boot/ -j4
In the contemporary computing landscape, the battle for user freedom has largely shifted from the operating system to the firmware layer. While the Linux kernel and GNU utilities are celebrated bastions of open-source software, the low-level code that initializes hardware—the BIOS, UEFI, and bootloaders—remains, for most users, a proprietary black box. This hidden code can contain backdoors, impose hardware restrictions, or simply abandon a device after a short commercial lifespan. The Libretech Flash Tool emerges as a critical software utility in the fight against this opaque ecosystem, acting as a secure, user-controlled bridge to liberate embedded systems from proprietary firmware shackles.
Before running the libretech-flash-tool, you need a Linux host system (Ubuntu/Debian recommended). Windows users should use WSL2 (Windows Subsystem for Linux) or a live USB.
