This section contains steps to flash the BIOS on your development platform for a Microsoft Windows* host computer.
The following instructions as based on the operator having a functional development platform and workstation that includes:
Product Development typically has a few distinct phases:
The onboard graphics acceleration hardware is capable of accelerating video encoding and decoding tasks. This functionality is exposed from the Video Acceleration API (vaapi) and the gstreamer-vaapi plugins.
A serial console can be created across the Bluetooth® service to send commands and display system messages.
The following sequence outlines how to enable the Bluetooth® serial console.
- Add a serial port channel to the adapter

The Intel® Joule™ module offers a multitude of I/O communication protocols to control signal flow and port out those signals to the macro world. Digital I/O can be directly controlled from the kernel and more easily controlled by the MRAA library. The following communication protocols are available.
Intel® Gen9LP features
- Gen9LP graphic engine can run at 450MHz or 650MHz according to model. See the model descriptions in the System on Module Overview.
- Intel 9th generation (Gen 9LP) graphics encoder / decoder engine
The default BIOS configuration table defines four dedicated PWM outputs as PWM_0, PWM_1, PWM_2, and PWM_3, each with programmable frequency and duty cycle.
The table below shows examples of hardware (register) based PWM programming.
The PWM variables that control frequency and duty cycle are controlled by the BASE_UNIT_INT, BASE_UNIT_FRAC, and ON_TIME_DIVISOR register settings and the following equations:
PWM frequency formula:
The BIOS defines events initiated by the PMIC_PWRBTN_N button. Beginning in version 161, reference BIOS provides three functions:
- Power on: press for 2 seconds to boot.
- Sleep mode: when powered, press for 2 seconds to put to sleep.
- Mechanical off: press for 10 seconds to power off.
