T113的OpenOCD在线调试的坑

我使用的是板子,发现JTAG默认配置的引脚是GPIOF0, GPIOF1, GPIOF3 and GPIOF5;改配置成PE8、PE9、PE10、PE11;还得做个电平转换,1.8转3.3;

xfel read32 0x020000f0   
0x0f3f3f33
xfel read32 0x020000C4
0xffffffff

xfel write32 0x020000f0 0xFFFFFFF
xfel write32 0x020000C4 0xFFFF6666

xfel jtag
xfel ddr t113-s3

然后运行:

sudo ./openocd-0.12.0-rc1/install/bin/openocd -d -f openocd_t113.cfg

有哪位大佬有ftdi的OpenOCD的详细配置么?
