Hi.

I have 3 questions about your board design:

1. Why do you use 2 F.Cu and 2 B.Cu Zone outlines instead of just use one for each side?
   2.There is a espetial reason for use 0.508 clearance instead a smaller one
   3.You make a big loop on 5V or A4 pin in the USB connector, is that really needed, because fisically is the same pin, I think it's not necesary, or I'm wrong?

If you change the rotation of some components it turn out a simplier PCB routing

When I updated openocd to 0.12 I'm to face a problem:

Open On-Chip Debugger 0.12.0 (2023-01-14-23:37)

Error: CMSIS-DAP command mismatch. Sent 0x0 received 0x3
Error: CMSIS-DAP command CMD_INFO failed.

In 0.11 version it wasn't:

Any ideas?

README.md says,

Firmware released under an GNU AGPL v3.0 license. See the LICENSE file for more information.

The image says,

Software GPL-3.0-or-later

And the LICENSE file says,

GNU LESSER GENERAL PUBLIC LICENSE Version 2.1

Which is correct?

I believe in this case as ARM originating source files are licensed under Apache-2.0, rest of the firmware code ought to be LGPL .

Could you clarify this and fix the document? (I suppose the image can be just removed.)

Hi Mr. Cat,

First thanks for your great work. I have found a variable named DAP_TransferAbort which is not set as 1 forever. It seems the porting work has left out something there.
