AWR1843: AWR1843　USP

Hi Hiroyuki-san,

Could you confirm if you can not see any of COM port listed in the device manager when you connect USB cable from AWR1843BOOST EVM to PC?

Is it EVM or your custom board with AWR1843 device?

Regards,

Jitendra

I use my custom board.

I connect AWR1843 with TM4C129ENCZADT3.

In that case, I assume that you are connecting AWR1843 over UART pins to TM4C129ENCZADT3. so you need to read data over UART from AWR1843 using application running on TM4C*** MCU.

And TM4C129ENCZADT3 is connected to PC over USB cable.

Please fill me up with your full device connection and how it is connected to your PC over USB.

Regards,

Jitendra

Hello, I made a wiring diagram of the circuit immediately.

The power line etc. are omitted.

J8 is a USB connector (2.0).

The connection diagram is described in the attached file below.

Hi,

Please make sure that you follow the schematics of the AWR1843BOOST

thank you

Cesar

Hello, thank you for your reply. Doesn't it work with the circuit diagram I wrote?

We will ask the hw team to review the schematics.

We will get back to you by end of the week

thank you

Cesar

Is that the complete schematic? Where is the power for the radar or the TM4C? If that is your complete schematic then you are missing several key components.

This is not a complete schematic.

It is from the power supply on the radar side.
The AWR1843 is inputting 3.3 V, 1.8 V, 1.24 V, 1.0 V.
(3.3 V: E15, R10)
(1.8 V: B11, B12, F5, K5, R9, D15)
(1.24 V: G15, H15, N11, P15, R6, P14)
(1.0 V: G5, H5, J5, C2, D2)

A 3.3 V voltage is input to the TM4C129ENCZADT3.
(PK6, PK7, P19, VDDn, P18, N4)

If you have any other necessary information, please let me know.a.pdf

Please provide the full schematic with all connections and components. It is not possible to review without it.

If what you have provided is the complete schematic then you are missing several necessary components. You need to review the hardware design checklist and make sure you include all of the required components for the AWR1843 device.
