Minimum Requirements for Operation
PHYTEC recommends the following minimum requirements for basic operation of the phyCORE-i.MX8X SOM:
•
Connect all available 3.3V input pins to a power supply on a custom carrier board that provides at least
2000 mA.
•
At minimum, connect the matching number of ground pins neighboring the 3.3V pins. However, PHYTEC
highly recommends connecting all ground pins for proper implementation of the phyCORE-i.MX8X SOM.
•
Implement at least one of the supported boot devices to support loading and executing application
i.MX8X Processor Reference Manual
for details regarding all supported boot
modes. The phyCORE-i.MX8X SOM provides an on-board eMMC, but it is recommended to support
another boot source for development and debugging.
•
Strap the boot signals to the desired levels at POR to configure the required boot mode for your
application (i.e. using a DIP switch). This is required on the carrier board to override the default boot
mode set on the SOM. Refer to the
•
Implement a serial debug port (such as via UART) to interface with the module for development.
