Kontron mAL10 Computer-on-Modules platform¶
The Kontron mAL10 COMe is a credit card sized Computer-on-Modules platform based on the Intel Atom E3900 Series, Pentium and Celeron processors.
Technology¶
| COMe Type | mini pin-out type 10 |
| SoC | Intel Atom x5-E3940 (4 core) |
| GPU | Intel HD Graphics 500 |
| Coprocessor | Intel TXE 3.0 |
| RAM | 8GB DDR3L |
| eMMC Flash | 32GB eMMC pSLC |
| USB3 | x2 |
| USB2 | x6 |
| SATA | x2 |
| LAN | Intel I210IT, I211AT |
| Super IO/EC | Kontron CPLD/EC |
| HWM | NCT7802 |
Building coreboot¶
The following commands will build a working image:
make distclean
make defconfig KBUILD_DEFCONFIG=configs/config.kontron_mal10
make
Payloads¶
- SeaBIOS
- edk2
- Linux as payload
Flashing coreboot¶
The SPI flash can be accessed internally using flashrom. The following command is used to flash BIOS region.
$ flashrom -p internal --ifd -i bios -w coreboot.rom --noverify-all
Hardware Monitor¶
The Nuvoton NCT7802Y is a hardware monitoring IC, capable of monitor critical system parameters including power supply voltages, fan speeds, and temperatures. The remote inputs can be connected to CPU/GPU thermal diode or any thermal diode sensors and thermistor.
- 6 temperature sensors;
- 5 voltage sensors;
- 3 fan speed sensors;
- 4 sets of temperature setting points.
PECI is not supported by Apollo Lake Pentium/Celeron/Atom processors and the CPU temperature value is taken from a thermal resistor (NTC) that is placed very close to the CPU.
Untested¶
- IGD/LVDS
- SDIO
Tested and working¶
- Kontron CPLD/EC (Serial ports, I2C port, GPIOs)
- NCT7802 [HWM](#Hardware Monitor)
- USB2/3
- Gigabit Ethernet ports
- eMMC
- SATA
- PCIe ports
- IGD/DP
TODO¶
- Onboard audio (codec IDT 92HD73C1X5, currently disabled)
- S3 suspend/resume
