Hi,
In the bootmode - SPI section of IWR6843 Bootloader Flow:
Follow the communication protocol used by the mmWaveSDK mmWaveLinkrlDeviceFileDownload API (described in the mmWaveLink API Doxygen documentation referenced in the mmWave SDK User Guide) to communicate with an external host to receive the images to be loaded as message packets over the SPI.
Where can I find the document about the detailed protocol?
Cheers,
Tom
