Re: Problem getting back into download mode
GPIO8 needs to be high for the chip to enter download mode - is that the case in your circuit?

Re: ESP32-C6-DevkitM-1: GPIO Allocation
For all these peripherals, you can basically pick any (otherwise unused, and watch the strapping pins) GPIO. These peripherals all can be routed through the GPIO matrix, so they can connect to any pin.

Re: ESP32-C3 power consumption when held in reset
For reference: this is an ESP32-C3-Wroom-02 (containing the same ESP32-C3 chip) when held in reset. I measure the fraction of an uA that I'd expect.

Re: ESP32-C3 power consumption when held in reset
I don't know what to tell you... something is still leaking current somewhere on your design. Might be as simple as a resistive divider, might be something as flakey as slightly-conductive flux residues. For instance, you don't happen to have a pullup on EN that conducts current to ground when you p...

Re: ESP32S2 with CH340F custom board not working
On the USB connector, the CC pins should be connected to a 5.1K pulldown each. If you don't have that, an USB-C-to-USB-C cable won't work; it won't give the board any power. To bypass this issue (for debugging), you can use an USB-A to USB-C cable, that won't have that issue.

Re: Seems to program but won't run code
Just to check, C7/C8 are not populated on your board, right? (They shouldn't be, a capacitor there will interfere with USB)

Re: ESP32, UART2 uart_write_bytes, no serial output
Yes, that should happen. (Although you should *not* connect the 3.3V line, as it's an output on both the devboard and FTDI board side.) Can you sanity-check your setup by connecting the Tx and Rx of the FTDI board together (disconnect them from the ESP32) and typing something on the minicom connecte...

Re: Using ADC1 triggers the watchdog
Can you try to change over to the newer driver, see if that makes a difference?

Re: Which Esp32 should be chosen in terms of current draw at the time of data reading?
If you only take the measurement to accumulate them to later send as a batch, any chip with a low-power coprocessor may be able to do that; that CPU tends to use a fraction of what the main chip uses. I'd suggest the ESP32-C6 in particular for that as we improved the low-power coprocessor by a lot i...

Re: What are hardware issues behind Vl6180x didnot light up or blink?
Can you post your source code? Do you get any messages on the serial terminal that may lead us in the right direction? Checked all your connections to see if they're in the right locations and connect properly? What did you try to debug the issue by yourself already?
