UCD9244: UCD9244 + TMS320C6678: Occasional power-up failure with CVDD rail

Part Number: UCD9244

The power up failures are hard to troubleshoot.

  • Would populating a board with just the power system be a viable alternative?
    Often it can be beneficial to validate the power is functioning standalone before trying to bring up the complete system.
    I know the C66xx parts have specific power sequencing requirements and have run into previous issues associated with sequencing.
    Unfortunately, I am not an expert on the DSP devices.
