In the fields of digital signage, self-service terminals, medical equipment, and industrial automation, the Thin Mini ITX board type is an ideal choice for space constrained applications due to its compact 170mm × 170mm size, machine thickness below 25mm, and standardized installation hole positions. The AmITX-AL-I launched by ADLINK is a low-power Thin Mini ITX embedded motherboard based on Intel ® Atom ™ X7/x5-E3900 series Pentium ® N4200 and Celeron ® N3350 SoC(Braswell), Integrated with Intel ® Gen9 LP graphics core, supporting three independent display outputs and 4K video hardware encoding and decoding. This board is equipped with a variety of I/O interfaces, including dual gigabit Ethernet ports, 6 serial ports, 4 USB 3.0 ports, PCIe x1, and Mini PCIe/mSATA expansion slots. It also features ADLINK's unique SEMA (Smart Embedded Management Agent) onboard management controller, which enables hardware monitoring, watchdog, dual BIOS, and remote management. This article will provide a detailed deployment and debugging reference for system integration engineers from the aspects of hardware architecture, interface definition, jumper configuration, installation points, SEMA functions, BIOS tuning, and system resource allocation.
MSATA does not recognize JP11 and is not set to mSATA mode. Change JP11 to 2-3
COM1/COM2 communication abnormal jumper mode does not match external device; Power supply setting error check SWS1M/SWS2M mode switch, verify JP7~JP10 power supply selection
LVDS shows no display or backlight does not light up. Panel voltage/backlight voltage/polarity settings are incorrect. Check JP2/JP3/JP5/JP4 to confirm consistency with LCD specifications
The system does not start automatically (after AC power failure). In the BIOS, State After G3 is set to S5 and changed to S0 State or Last State
Watchdog not triggered Power Up Watchdog disabled by F12 or not enabled in BIOS to check watchdog settings, does not press F12 when restarting
SEMA status LED flashes with specific code BMC detects hardware abnormality and checks against the abnormal code table (such as BIOD_FAIL, NOV12, Memoriy_ERROR)
Dual BIOS cannot switch BSW1 switch not set correctly. Confirm that the jumper caps at positions 1-4 and 2-3 are in good contact
USB keyboard is invalid under DOS. Legacy USB Support is not enabled. Enable Legacy USB Support in BIOS
Remote serial port cannot connect Console redirection. Parameter inconsistency check for baud rate, data bits, stop bits, flow control, and terminal matching
