[Feature Request]: Upload firmware via jtag. (VSC-427)

[ghost]

I want to use your extension, but impossible upload firmware in my case.
My pcb has only jtag port.
No serial.....

Thank you!

Thanks for the feature request, we already have a plan in our roadmap to integrate jtag flashing directly from vscode, but this feature could take sometime to release.

Till then you can flash individual bins using openocd from terminal/cmd

$ openocd -f board/esp32-wrover-kit-3.3v.cfg -c "program_esp <app_name>.bin 0x10000 verify exit"

More info can be obtained here

So, when approx will be released?

[pwmb]

This is planed to be released in v0.6.0, while we cannot comment on exact date because it's dependent on other projects like idf, openocd, etc.

We will keep you posted on this issue for any updates

@pwmb: I tried this on the Adafruit HUZZAH32 without success.

I can flash this board using the serial cable but I cannot using JTAG.
I can debug this board with my JTAG connection - without problem. (The same command as below - without the -c option)

Here is the output:

C:\somepath>openocd -f ./esp-huzzah-32.cfg  -c "program_esp build/myapp.elf 0x10000 verify reset exit"

How to work around this problem?
Let me know if this should become a separate issue.
