Hello, there really isn't anyone in this forum who can help me with the pin output scheme on this board to make a jtag.
Or how u-boot can be rewritten from scratch on this board.

I don't have uboot, so I can't give commands in the terminal, that's why I can write uboot from mmc with a command file? Or I need a jtag to recover this card. Thanks.
