AWR1443: LP XDS 110 debug probe to flash firmware for awr1443 to enable SPI communication.

Gohar Ali
Prodigy 10 points
Part Number: AWR1443

Tool/software:

We have developed a custom PCB based on the AWR1443 that includes both JTAG (4-pin) for programming and SPI for data communication. The goal is to have the AWR1443 operate as an SPI slave, sending real-time sensing data (range, velocity, and angle) to an ESP32 host MCU via SPI.

I understand that the default "Out of Box" and mmWave Demo firmware for AWR1443 streams data over UART and LVDS, but does not support SPI as a data output interface. I’ve confirmed this through documentation and testing.

Could you please clarify the following:

  1. Is there any existing precompiled .bin file or example firmware provided by TI that enables SPI streaming of detected object data (not raw ADC), ideally sending range/velocity/angle?

  2. If not, does TI provide any official guidance or examples for modifying the mmWave SDK (e.g., MSS or DSS source) to stream data via SPI?

  3. Are there any TI-supported configurations or projects where AWR1443 operates as an SPI slave and communicates radar output to a microcontroller?

The AWR1443 are correctly powered on and SPI lines are correctly connected. but I need to confirm whether such a firmware image with SPI output already exists , or whether I need to develop one from scratch.

Any help, links, or references would be greatly appreciated.

    We do not have such demo application in the SDK.

    You can refer to SPI example at C:\ti\mmwave_sdk_03_06_02_00-LTS\packages\ti\drivers\spi for AWR1443 and modify the code as per your requirement.
