用cmsis-dap仿真器连接的时候，出现这个报错，连接线和引脚约束检查好几遍了，还是没找到问题，有大佬知道咋解决吗 F:\tinyriscv\tools\openocd>openocd.exe -f tinyriscv.cfg Open On-Chip Debugger 0.10.0+dev-00914-g4cb81306a-dirty (2020-01-28-21:35) Licensed under GNU GPL v2 For bug reports, read http://openocd.org/doc/doxygen/bugs.html Info : CMSIS-DAP: SWD Supported Info : CMSIS-DAP: JTAG Supported Info : CMSIS-DAP: FW Version = 2.0.0 Info : CMSIS-DAP: Interface Initialised (JTAG) Info : SWCLK/TCK = 1 SWDIO/TMS = 1 TDI = 1 TDO = 1 nTRST = 0 nRESET = 1 Info : CMSIS-DAP: Interface ready Info : clock speed 1000 kHz Info : cmsis-dap JTAG TLR_RESET Info : cmsis-dap JTAG TLR_RESET Error: JTAG scan chain interrogation failed: all zeroes Error: Check JTAG interface, timings, target power, etc. Error: Trying to use configured scan chain anyway...
