Hi,
I am trying to connect AWR2243BOOST board to external host.
I have connected the following lines:
- NERR
- SOP[0:2]
- nRESET
- HOSTINT
- GPIO[0:2]
- SCL and SDA
- PGOOD
My question is, should I be able to configure the on board PMIC (LP87524J), and if so - how to do that ?
Regards,
Ron
Hello Ron,
Sorry for the late reply, this thread somehow got missed.
Are you trying to communicate with the PMIC via the AWR2243, or via an external host?
If you are trying to communicate to the PMIC from the AWR2243, you will need to make sure R197 and R198 below are populated. The communication with the PMIC is done using I2C. You can find the design files (schematic and assembly) at the link below to help you locate these components on the board. Once those are connected, you would need add the code to your application to write to the PMIC using I2C. We provide the I2C drivers in the SDK for your reference on how to setup I2C communication in your application.

If you are trying to communicate with the external host to the PMIC, you would need to connect the external host I2C lines to pins 17 and 19 on J5. Then, your host will be connected to the PMIC I2C and you should be able to communicate with the PMIC.
