Hi all,

I check the document sprugw0c TMS320C66X.

in the page 3-16, it mentioned i can change the register, like L1DCFG, in the supervisor mode.

How do i change the mode between supervisor and user.

Thanks.

Hi YaoTing
Sorry for the delay. What software base are you using?
Are you developing with Processor SDK?

Typically Supervisor and User mode setting is in the Memory protection Access(MPA) Registers. If you are not configuring any memory protection then you don`t need to configure it as the DSP by default configures all memory for Normal mode access so this only applies if you are using MPA.

IF you are simply looking to configure L1DCFG, then I would recommend that you look at the following header files in CSL that relates to cache configuration: (Please look at APIs that configure L1DCFG)

pdk_k2hk_4_x_xx\packages\ti\csl\csl_cacheAux.h
pdk_k2hk_4_x_xx\packages\ti\csl\src\ip\cgem\V1\cslr_cgem.h

Hope this helps.

Regards,
Rahul
