I just received two REV F boards from Mouser and I am having problems uploading on both. I am using an Ubuntu based distro and Arduino IDE v1.8.10. Sometimes it just works sometimes I have to try several times and on one of the boards currently I have not been able to upload for a few days. What is odd is the original firmware was easily uploaded over but my simple "Hello World" test are not. Is this a problem with talking on the same UART as the programmer is on causing some race condition?

Any suggestions appreciated.

Try the driver here: https://github.com/OLIMEX/ch340-dkms - follow the instructions.

Try to lower the upload speed.

Might be related to support of the software under your operating system. Worth checking the ESP32 package for Arduino forums and GitHub page for similar issues. It can be found here: https://github.com/espressif/arduino-esp32/issues
