https://gitea.osmocom.org/sim-card/simtrace/src/branch/master/hardware/pcb/g... I am a novice Xiaobai, I am very interested in this project. So I made the pcb by myself, according to the content of the website above. But I can't get it into the program, which annoys me. I don't know if it's my hardware that's wrong. It's still a problem with my software. I hope that the teacher who understands can help me check it out, thank you very much here.

I'm surprised about this question. This entirely depends on your mail client. You send an e-mail to simtrace@lists.osmocom.org and attach pictures just like in any e-mail...
Is the information on the above website up to date? The pcb made according to it is Simtrace2, right?

Welcome!
So I made the pcb by myself, according to the content of the website above.
This should work. It is the latest PCB design, as used for SIMtrace2 with SAM3S.
But I can't get it into the program, which annoys me.
Can you be more specific? Does the device enumerate on the USB bus if you plug it in? Or do you get some USB errors in your kernel log after attaching it? Or nothing?
I don't know if it's my hardware that's wrong.
You can do the obvious bits: * check if the supply voltages are correct (at the pins of SAM3S or the capacitors near it) * check if the SAM3S enumerate on JTAG, if you connect a JTAG programmer
