IWRL6432AOP: Can I apply FECSS firmware patches without serial flash?

Part Number: IWRL6432AOP

Tool/software:


I'm considering launching the user application without SerialFlash.
Regarding the FECSS Firmware Patch, would it still be applicable in a scenario where the user application is transferred via SPI/UART and executed on the M4 core without SerialFlash?
The patch binary file mmwave_rfs_patch_rprc.bin is expected to be combined with the user application using the tools mentioned in the below link question, and then transferred .

    Hello.

    Yes the firmware patch is still applicable even if you are not booting with SerialFlash.  For booting over SPI, please refer to the example in the SDK as it will provide the instructions on how everything should be formatted for the image and may answer some of your questions here as well.  It also provides the tool to convert the regular appimages generated via building the demo into the form needed for booting over spi.  You can find this demo in <SDK_INSTALL_PATH>/examples/drivers/boot/spibooting/.

    Sincerely,

    Santosh
