AWR6843: QSPI Clock Configuration.

Jesse Wang

Part Number: AWR6843

Hi TI expert,

Can AWR6843 QSPI clock be configurable while system is booting? That is, for example, how to set the QSPI's clock rate under 15MHz when booting?

Hi Jesse,

Is this for the download of SBL or application code?

Hi Jesse,

For the device bootloader initially the frequency is fixed. To change the SPI clock rate at boot it may be needed to modify the e-fuse bits. But with the SBL to download the application image the clock rate can be changed.
