Re: Failing EMC test (ADC channels not stable)

You're saying any adc1 pin with a lead even when not configured as rtcio or adc function will still couple the noise into the adc and it will go haywire? What is the green line that looks less affected?

Re: What is the purpose of CAP1 CAP2 pins?

Well 1.1v is a 57% increase vs 0.7v but this is only until the voltage drops under the internal load. So this will have the greatest effect on the low current and short duration deepsleep cycles.

Re: Is it possible to encrypt/decrypt buffer in RAM using Efuse block1/block2 keys?

No those keys are protected so you may as well just store another key in encrypted flash and use that.

Re: esp_partition_mmap is not decrypting partition data?

Did you enable flash encryption or just set encrypted flag in partition table?
