Hi,

Is it possible to boot from the main MCU through SPI in order to avoid using an external flash memory ?

Regards

Hello Geoffrey,

This is possible. You can find information on how to boot over SPI without flash in the TRM and also have examples of how to do this in the MMWAVE-L-SDK.

Sincerely,

Santosh

Hi Santosh,

Thanks, found it.

I imagine there are some drawbacks of using a host to load the image such as boot time?

That is correct as you are using 1 SPI line instead of 4 like you would with QSPI.

Sincerely,
