SRAM Partition

[gonzalezjl]

Is it possible to have discontiguous Non-Secure areas in SRAM to be used by the application?

&sram0 {

reg = <0x20000000 DT_SIZE_K(8)>;

};

&sram0_ns {

reg = <0x20002000 DT_SIZE_K(56)>;

};

&sram0_bsd {

reg = <0x20010000 DT_SIZE_K(64)>;

};

&sram1_ns {

reg = <0x20020000 DT_SIZE_K(128)>;

};

Thanks,

JL

Hi,

You could e.g. create some library that uses sram0_ns, and then link that with your application(that uses sram1_ns). E.g. In the same way that's done with the bsd-lib. Note that sram0_bsd is also non-secure. Note that if you are using MCUboot(e.g. used in application DFU), you would need to allocate more RAM to sram0.
