ESP32 WROVER (I) Pullup Resistors

[tony07881]

I'm making a custom PCB using the ESP32-WROVER (I). The silkscreen on my device says ESP32-WROVER-V4 and has 18 16 at the top. I've read through the documentation multiple times and have searched the forum but still I'm confused and have several questions.
1) Should I include a pull-up resistor on my board for any GPIO I use? Should it be 10k or 4.7k?
2) I want to use the on-board memory (16MB) but I'm not certain if I should configure it for 3.3V or 1,8V. Also want to confirm where I place resistor for config.
3) My custom PCB was recognized as a serial device on my Windows PC but I could not get the SW flash to execute. I'm using reset circuitry found in a number of examples, but the SW flash never kicks off (using the latest Arduino IDE). I do not have any pull-up / down resistor on GPIO 0. Wondering if I should?
Any words of wisdom or pointing me to pertinent information is greatly appreciated. Thanks

1)No need...
2)It is 1.8V on-board configured. No external resistor needed. But take good care of GPIO12 whose power-on status decides the supply voltage for flash. And also, we can configure registers to change the voltage level after power on...
3)Please post your schematic here, thanks...

Thanks for the response. If no need for pull-up resistors, let me clean up my schematic a bit and I will post it. I did read that correctly? No need for pull-ups?

Hey, you can post your schematic here and we can help to have a double check.

Sorry for the delay in reply. Had an accident and ended up in hospital for a while. I've attached a pdf of my updated schematic. The update corrected a circuit error and removed pullups. Happy to hear any feedback. Thank you.

Schematic is posted. Interested in any feedback you can provide. Thanks!
