I am currently having an issue reviewing the MAX77714 EVK where the 32k XO isn't running. Its not really a hardware issue as I can get the XO to run just with the capacitance of 2 10x scope probes. The issue has to do with configuring the PMIC to enable its on die load capacitors for the 32k oscillator.
I can't even try to enable the load capacitors because the evaluation software doesn't have the correct register map for the PMIC. The evaluation tool locates the 32KLOAD bitfield in register 0x31:
When actually the bitfield is in register 0x30 (from the datasheet: https://datasheets.maximintegrated.com/en/ds/MAX77714.pdf ):
Actually as I write this, even if the 32KLoad register was addressed correctly in the evaluation software it is readonly so I still wouldn't be able to change it. So why isn't it booting with a value of 0b00 instead of 0b10? Wrong OTP config?
So, my questions is what do reviewers typically do in this situation?I don't want to write a scathing review over something so silly.
I suppose I will start by seeing if maxim will confirm the issue with the EVK and see if they can provide a software fix or want to send new hardware.
One of the uncertainties I had with my last review was determining if I am reviewing the silicon product or the evaluation platform. In this case, am I reviewing the MAX77714 or the EVK and software for the MAX77714? Or, a bit a both? Or, is it up to the reviewer?
Thanks
