ADM-XRC-9R1 User Manual
V1.7 - 16th Sept 2020
3.8 Configuration
3.8.1 Power-Up Sequence
At power-up, the PS will load the first-stage bootloader from the memory interface selected by the Boot Mode
select switches.
The first stage bootloader is responsible for configuring the FPGA and PS attached interfaces.
Note:
If an over-temperature alert is detected from the System Monitor, the target will be cleared by pulsing its
Automatic Temperature Monitoring
.
3.9 System Monitoring
The ADM-XRC-9R1 has the ability to monitor temperature and voltage to maintain a check on the operation of
the board. The monitoring is implemented using the Atmel AVR microcontroller.
Control algorithms within the microcontroller automatically check line voltages and on board temperatures and
shares the information with the PS.
The following voltage rails and temperatures are monitored:
