Re: USB issue on ESP32S2 MINI1 (ESP32-S2FH4)

Thanq so much for your replies guys! The issue is resolved. On our PCB, we added resistors( zero ohms) and capacitors on the D+, D- lines as suggested by espressif. But, we are using esp32s2 controller and NOT soc. This leaves all our resistors and capacitors(maybe) prone to external noise,thus res...

Re: USB issue on ESP32S2 MINI1 (ESP32-S2FH4)

Can you provide schematics if it's a custom board?
Do you have any cap on d+/- lines?

Re: Strapping pins (vz GPIO2) on C3

Hi,

IO2 + IO8 should be pulled up
IO9 you can leave floating and ground when you want it to go into download mode

At least that's what I'm doing.

esp32-c3 io-mux default pin state during reset

Hi,

esp32-s2 has in its datasheet (page 42) specific pin state At Reset & After Reset. I would assume this is during the pin EN low and when EN is high.

esp32-c3 only has the pin state specified (page 17) for After Reset. Is there no difference between At/After Reset for this chip?

Re: esp32-c3 native usb problems

Hi Roland, I already had the driver installed using PowerShell cmd. Anyway, I found Zadig where I found two "USB JTAG/serial debug unit" (Interface 0 and 2). Interface 0 ========== Driver "usbser v10.0.19041.906" [green arrow ==>] WinUSB (v6.1.7600.16385) WCID had red cross mark Interface 2 ========...
