SD->JTAG adapter for F3?

I can see some old posts about getting JTAG working on the F3 board, but … is there an off-the-shelf adapter for the SD/MMC card to a JTAG format? One that can be bought.

But it LOOKS like the pinout is a bit different from the few adapters (e.g. ESP32) that are out there.

If there’s already sch/brd/gerbers that I can just get made, that would also be a great solution.

Some chips from Allwinner and other manufacturers share the JTAG debug port with the SD card. If you need to perform JTAG debugging, you can use something like this: 平头哥CKLink Lite至全志TF卡调试转接方案 - 立创开源硬件平台

Awesome, thanks for the link.

Sadly, it looks like I’ll need a China phone number to be able to register for that site. (seems like my jlcpcb.com login won’t work)

Any chance you could export it in the Altium format for me?
