Dear all, I and Suzuki made a patch to bring the DM355 into Deep Sleep Mode. It is for TI LSP 1.20 (Linux 2.6.10), and based on: http://www.mail-archive.com/davinci-linux-open-source@linux.davincidsp.com/msg04407.html
Running command below, DM355 will go to Deep Sleep Mode: # echo mem > /sys/power/state In the process, DM355 sends a register write command to MSP430, offset = 0x19 and data = 0. You should implement a register 0x19 write function for MSP430 to assert its DS_ENABLE pin low. Asserted DS_ENABLE pin high, DM355 will exit Deep Sleep Mode. A proglem is that this code stops the ARM subsystem, but its consumption current does not seem to change. Any idea to reduce the current is welcome. INAGAKI Takahiko
