Hi all,
The dm6446 has arm and dsp sleep mode management. Does anyone enable the sleep
mode in your davinci system? Can you give me am example? I get the message "You
can enable the wait-for-interrupt mode via the CP15 register #7 using the
following instruction: mcr p15, #0, rd, c7, c0, #4" in the
datasheet(TMS320DM644x DMSoC ARM Subsystem Reference Guide.pdf). How to call
this asm instruction in C function? I tried to use __asm__("mcr p15, #0, rd,
c7, c0, #4"), but get a err message"Error: bad or missing expression -- `mcr
p15,$0,%r3,%c7,%c0,$4'" when compiling.
best regards
