dear e2e ,

we are trying to erase on chip flash in tms570ls3137 by using application interface(API021) . Before using API for erasing flash i want change mode of CPU from non-privilage mode to privilage mode.

We didn't find description on how to switch from user mode into privilege mode inTMS 570 datasheet. can u tell how to change mode?

I am new to this field , if there is any source code related to changing user to privilage mode for refrance , can u send ?

hi ,

i saw the example in the attached link .

I am not getting what are the changes made in "sys_intvecs.asm" file . My program is hanging in this file at undefEntry line when i am using Fapi_setActiveFlashBank() function.

In ISR_SWI(unsigned r0, unsigned r1, unsigned r2, unsigned r3) function in the example , what value send to variable r0 ,r1 , r2.

which register we have to use to set system mode.
