Can't upload to NodeMCU
Posted: Fri Aug 11, 2017 7:21 amHi,
I have been following this guide:
https://github.com/nodemcu/nodemcu-devk ... ted-on-OSX
I installed the driver and can see this port: /dev/cu.SLAB_USBtoUART
I can connect to it via serial but I just see some odd characters/data coming out that is not human-readable. In hex view there are a lot of zero value bytes.
When I try to disconnect from serial I can't and I have to reboot in order to connect again.
In Arduino (I have installed ESP community libraries) it's same, I can see the port but sketches don't upload and after trying the port menu is greyed out and I have to reboot.
Are there some serial commands I can issue to check if the board is working? Do I need to flash the firmware? I have used many types of Arduino before but this is my first try with ESP. Am I just missing something or do I have a faulty board maybe? I've tried two cables and it seems same with both.
