IWR1443BOOST: Sending firmware from external MCU

Akshay Patel1

Part Number: IWR1443BOOST
Other Parts Discussed in Thread: IWR1443, IWR1642

Hi team,

As mentioned in IWR1443 datasheet page 64, device can receive firmware image from external MCU over SPI. This configuration is helpful when no serial flash is connected.

I want to know format in which flash data is to be transferred to IWR1443 over SPI. Is there any document describing the workflow.

Thanks,

Akshay

Hi Akshay,

Thanks for your patience. We don't have an example to demonstrate device firmware download over SPI from an external MCU without using a Serial Flash. However, you can refer to the following resources for detailed discussions and helpful hints on this topic.
