Hello,

 

I am trying to find how much max memory can be used in Cortex M4 of IMX7ULP in Low power mode.

 

As I see from the ref manual, it seems that max 256KB can be used from internal RAM. 

Can someone please help to figure out if there is way to increase this RAM on M4 side?

Is there a way to access DDR conneted with A7 from M4 while keeping A7 in sleep mode?

 

Thanks in advance,

 

Regards,

Vivek
