13 Reading On-board PMIC and MPSoC Telemetry

The Infineon PMICs on the Ultra96-V2 connect to the ZU+ MPSoC device via PMBus. This
allows us to read important telemetry from the power regulators on board. To learn more about
this feature, read this blog and view this recorded webinar:

https://www.element14.com/community/groups/power-management/blog/2017/10/11/benefits-
of-power-system-telemetry-using-pmbus

https://www.element14.com/community/events/5588/l/pmbus-and-power-supply-telemetry

You can also view a more advanced project related to this on Hackster:

https://www.hackster.io/AlbertaBeef/monitoring-power-on-the-avnet-platforms-e52a23

For now, we will show the simple method of reading back the telemetry.

1. Connect to the Linux Terminal either through SSH or the UART. To see the available I2C

busses available, type in your console

i2cdetect -l

Figure 24 – I2Cdetect

This shows all the available I2C busses on the Ultra96-V2. The one corresponding to the PMICs
is found based on the hardware connections in the schematic. The signals are called
‘PMIC_SCL’ and ‘PMIC_SDA’ and are connected to Channel 4 (SC/SD4) of the I2C Expander
U7, which is i2c-6 in Linux.
