Re: RTC_I2C SDA sampling

Probably not, you could try the SW i2c https://github.com/tomtor/ulp-i2c or maybe a delay line?

You have to write some other registers and it's not that useful without LNA

Re: uart_wait_tx_done() fails when sending a single byte

No it is hw controlled. That code path is to check if tx is already done. The idea was if the fifo is empty but the last byte is still being shifted out it would wait for the tx done interrupt. I am not sure of exactly when the fifo count goes to zero.

Re: ESP32 Flash Download Tool

Read up on how the dev boards use a dumb usb-uart chip with transistor circuit to put chip in download mode and then decide how you want to do it.

Re: Power supply and UART Connection for ESP-WROOM-32D

It has weak internal pull so external pull 10k or less should be fine. Should be ok to use for CS.

Re: ESP32 Flash Download Tool

Why wouldn't you just use it as a transparent bridge and pass everything?
