Dear IFX,

 

Recently, we are going to use the 20719 for the biometry project. 

We need to add a library to extract some templates but the library's size is too big to use (Over 200k).

I've checked the free RAM size of 20719 but we need to allocate some RAMs to use that library.

After merging the library to the hello sensor sample application, the free RAM size is too small to use.

 

We found the 89820 code is on the XIP and we can make more rooms to allocate.

If possible, we want to use the same way to 20719. Can we use the 89820 methods to 20719?

If we can enable the XIP in the 20719, the free RAM size is enough to use.

Thanks in advance.

 

Regards,

Wayne

Hi,

 

I've tried to add the "APP_XIP=1" but there are no changes in the build result.

I think we need to add the APP_XIP section on "ld" file but there is no "ld" file in the current work-space.

I found the 20819 and 20820 have the "20820A1_xip.ld" file.

Could you check that?

 

Regards,

Wayne
