PCNT + RMT vs. GPIO + MCPWM

[DrMickeyLauer]

So here's an odd one... I have a custom board based on ESP32S3 which works pretty much normal. However...

when I input a PWM signal to a certain GPIO, PCNT and RMT do not detect _anything_. Nothing.
I have played with different ways to initialize and configure the peripherals, preconfigured GPIOs, anything, I can't get them to detect pulses.

Whereas polling the GPIO, reading via IRQ, and even MCPWM's counter are doing the right thing.

What could be the problem?

Turns out the manufacturer incorrectly inserted 100KΩ resistors instead of 100Ω... it's a wonder that direct GPIO access and MCPWM did work at all.
