anyone using Ubuntu under Windows 10?

Postby Digital Larry » Wed Mar 11, 2020 3:23 am

I want to get the ESP-IDF build tools running on my Windows machine as it's the fastest one I have. I did get the hello_world to run under the ESP-IDF Windows native command prompt but this is not Linux. The reason I want to run Linux is to be able to streamline development of audio algorithms using Faust, which doesn't have direct Windows support.

Here's the result of attempting to upload hello_world to the AITinker ESP32-A1S board using Windows 10 Ubuntu.

Code: Select all

Windows detects the board on COM4, which translated to Ubuntu talk, is ttyS4. You can see that there is some communication with the board, but it ultimately fails.

I am using Ubuntu with Virtualbox on a Win10 machine. Without any issues.
Dont forget to configure the number of CPU cores in Virtualbox to use full CPU power during build

OK, that's another approach I might try. So, you don't have any problems flashing the board over USB using Ubuntu in Virtualbox? Looks like from the error I got it had some problem adjusting the baud rate. And to be clear, this error does not happen when doing the same thing in the Windows native ESP-IDF command prompt on the same machine.

Thanks,

DL

No issues at all. Just passthrough the connected USB port to Virtualbox, that's it.

I do a lot of development with Ubuntu under WSL on Windows 10. I've since switched to using openocd (running under Windows) to flash my boards, but when I was still using the bootloader, I ran into a similar issue.

I found the discussion on a GitHub issue helpful - oddly enough, certain baudrates work with the WSL serial port passthrough and others don't.

Besides running slower at 115200, bumping it up to 921600 works for me, as does 1500000.

I've tried setting different speeds in the menuconfig

Serial Flasher Config-> 'idf.py monitor' baud rate (921600 bps) --->

No matter what I set it to, when the program goes to flash the board, it still reports as 460800.

Hmm, I'm not sure what would cause that issue. Fow now, maybe just manually pass in the baudrate with -p, i.e:

Code: Select all

idf.py -p /dev/ttyS4 -b 921600 flash

Putting the baud rate on the cmd line works, thanks!
