Hi,

Where is the entry point of initial qspiflash in the mmwaveSDK while powering up awr1642 system?

Beacuse I check the mww_mmw.mak file, there is not qspiflash lib included.

Thanks.

Hi Cesar,

That is because when I am porting the qspiflash driver to mmw demo.
I found that the original mmwSDK(mww_mmw.mak) is not included qspiflash lib, but the mmwSDK system can work normally.
So, I tried to find the reason, and feel some confuse about the question.

Could you help me ?
Thanks.

During boot, the BSS R4F is in control of the QSPI. None of the SDK's demos include the QSPI flash driver.

There is an app note that shows you how to include this driver into an existing application. It can be found here:

Hi dave,

Per your answer.
If I change the qspiflash brand , like macronix or micron , how does the BSS R4F decide which qspiflash brand and boot the system?

Thanks.

This is a different question. The original question was how to port qspiflash driver, which I answered above.

WRT to changing flash types, there is a post in this thread that discusses what the Bootloader expects:
