Debugging fails

Software Development
1

Hi,

I recently got Field and ST-Link V3 MINIE.

Seems like I am struggling to connect the debugger.

First of all, when the debugger is connected, I should or should not have the USB connection also or does that matter?

Second of all, could somebody be kind to help me find out where am I making mistake,

here’s my openocd output:

make program
openocd -s /usr/local/share/openocd/scripts -f interface/stlink.cfg -f target/stm32h7x.cfg \
		-c "program ./build/Blink.elf verify reset exit"

Thanks in advance,

You need to power the Daisy when using STLINK. If it’s a Seed, you can power by USB or the power pins. If it’s a patch.Init(), it can be powered by Eurorack case.

@tele_player thanks for getting back to me this quick!

I am using Field and it is currently connected to the power.

Do I need to connect the USB on Seed as well?

As long as the Seed is getting power, you’re good. So, no, you don’t need to connect USB to Seed.
I’ve never used a Field, so I don’t know if maybe there is some way it interferes, but there shouldn’t be.

Are you sure the stlink cable is properly connected?
Have you successfully programmed using make-dfu?
What OS are you using, Mac, Linux, Windows?

@tele_player I connected the stlink cable as described here, 1. Setting Up Your Development Environment · electro-smith/DaisyWiki Wiki · GitHub

I successfully programmed using make program-dfu through the USB connection.

If I try the same command while only connected through the stlink, I get the following error,
