	Hi again I'm trying to get to grips with an ESP32 and can build and upload sketches. However, the serial window doesn't appear to work. I have read the notice about SiLabs driver v10.x, but I don't have the given option to roll it back and wondered if this 10.x issue is fixed now. I can see the device in Arduno and also with HTerm, but I can't switch to these quickly enough to see what's occurring in setup without slugging it with a delay(10000). I am guessing this is the reason the option to upload files to SPIFFs doesn't work. With Verbose ON, the output window simply shows as attached. Thanks

	The silicon labs driver for windows universal (v10x) is never going to work with normal windows c# access. It's seems to be the way the driver manufacturer wants to work. You should install the 6x driver. We will in the future move away from the managed microsoft serial interface and revert to the really old way of doing things. For all other errors please submit the information shown in yellow at the top of this page

	OK I got the 6.X driver installed and output now appears in the serial terminal window. The procedure, if it helps others, is to uninstall the device and then download/re-install the 6.X drivers from here: https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vc... However, the utility to upload files to SPIFFs still doesn't work. With verbose ON, all that happens is that shown on the screenshot in my first post. Nothing else. So I didn't really think I'd need to attach a 1 line text file.... But if I occupy the port with, say the Arduino port monitor, then I get this: ESP32FSUpload.exe Traceback (most recent call last) File "esptool.py", line 2959, in <module> File "esptool.py", line 2952, in _main File "esptool.py", line 2652, in main File "esptool.py", line 222, in __init__ File "site-packages\serial\__init__.py", line 88, in serial_for_url File "site-packages\serial\serialwin32.py", line 62, in open serial.serialutil.SerialException*: could not open port COM60: WindowsError(5, Access is denied.)

	Yes please always post it saves you having to give the information that is always required such as esp tool chain version and shows your config and shows the patterns. Enabling Verbose upload in this case is also useful. It is also required to say which ide you are using, vs or atmel. If vs then which vs version.

	Ah. I see. It was not obvious that there is an uploader verbose as well as a compiler verbose... With this on, it does actually return a message that it's done its thing: Changing baud rate to 921600 Changed. Configuring flash size... Auto-detected Flash size: 4MB Compressed 1503232 bytes to 3220... Writing at 0x00291000... (100 %) Wrote 1503232 bytes (3220 compressed) at 0x00291000 in 0.0 seconds (effective 255869.7 kbit/s)... Hash of data verified. Leaving... Hard resetting via RTS pin... SPIFFS Image Uploaded Maybe it was working all along...but perhaps it may be useful to have the last 5 or 6 lines written in non-verbose upload mode. Thanks! All good now. I think.
