The Davinci EVM reset circuitry is designed to pull the output of U46 & U45 low in the event of DSP_CORE_VDD dropping out. However, the reset signal (1.8V.SYS_RESETz) to the DM6446 coming from U44 will not cause the processor's reset to be pulled low, due to diode D5. If DSP_CORE_VDD is lost shouldn't the processor reset (1.8V.SYS_RESETz) also be pulled low to reset the processor in the event that DSP_CORE_VDD comes back up?
