AWR1843: How to reduce the SBL load time

Shawn Li(Radar)

Part Number: AWR1843

Hi team,

My customer's APP is around 700K, they are using sbl_imageLoader function and the load time is around 110ms. Can we help reduce this time?

Regards,

Shawn

Hi,

The SBL Load Time is dependent on the QSPI clock speed and size of the image to be loaded.

Q4. How much time does SBL take to boot up and time to switch to the application?

If the QSPI uses highest possible speed and the image has been optimized for memory, than there are no other ways to speed up the SBL loading time

thank you

Hi Cesar,

Can you help explain "the image has been optimized for memory" more specifically?

This means that compiler optimization levels used will optimize the code size of the generated executable

thank you
