module.
FAN_TACHOIN: External FAN Tachometer Input. +3.3V_RUN voltage signal
microcontroller
FAN_PWMOUT: PWM output for FAN speed management, +3.3V_RUN voltage signal. It is managed by
SPKR: Speaker output, +3.3V_RUN voltage signal, directly managed by
THRM#: Thermal Alarm Input. Active Low,
microcontroller. This input gives the possibility, to carrier boa
throttling.
THRMTRIP#: Thermal Trip Output. Active Low,
microcontroller. Thermal Trip indicates an overheating condition of the processor. When goes active, the system immediately transitions to the S5 State (Soft Off).
3.2.17 Manufacturing signals
®
According to Qseven Standard specifications, rel. 2.1, on pin designed as MFG_NCx ( 207÷210) are carried through a multiplexer NXP i.MX8M Internal UART1
signals for firmware and boot loader implementations. Pin 204 (MFG_NC4) drives the selection pin of the multiplexer to enable debug UART1. This pin must be floated
to enable debug UART
Pin 207 (MFG_NC0) signal
UART1_RTS
The UART interface available on MFG_NCx pins is reserved only for the manufacturing phase; it must not be used by the customer.
It is not possible at all to use these pins to trace the software (for debug purposes)
