IWRL6432AOP: How to perform firmwre update/flash of iWRL6432AOP from another MCU?

Bhavya Mathukiya

Part Number: IWRL6432AOP


Tool/software:

Hi Team,

I am currently integrating the iWRL6432AOP sensor into my device. The sensor communicates with a master MCU via a UART interface.

While I can flash the iWRL6432AOP-EVM using the mmWave Visualizer tool in a development environment, this method is not feasible for field updates.

Could you please provide guidance and reference sample code for flashing or updating the firmware of the iWRL6432AOP through an external master MCU?

Your assistance with this would be greatly appreciated.

Best regards,

Bhavya

    Hello.

    You can use a secondary bootloader to update the image that is booted by the device for field updates.  You will have to flash this first but then afterwards you can communicate with the device over UART to transmit a new image.  You can find the SBL code in the SDK under <sdk-install-location>/examples/drivers/boot/sbl.

    Sincerely,

    Santosh
