For the first time you need to flash all of the bin files - I suspect you only flashed the large firmware one.
The zip file for esp32 in the latest firmware release has all of the files.

Also before flashing, its a good idea to erase the firmware entirely. I use something like:
esptool.py --port [insert_port_here] erase_flash
if you're using esptool. I noticed that the ESP32 was more sensitive to this issue (requiring the flash to be erased before uploading the firmware) than the ESP8266.
After playing around with ESP8266 using Espruino, I thought to give ESP32 a shot. After successfully flashing the Travis cutting-edge build, I tried to connect to the board using the Espruino web ide, which either gives me this endless log of recurring error
or show this error
As suggested in the docs, I also tried another tool to connect to ESP32, RealTerm (seems that cutecom and minicom aren't for Windows), which shows similar log of errors.
Any guidance will be appreciated.
