ESP8266 and ST-Link V1 Problem

[NKK72]

Hi,

I try debug ESP8266 using ST-Link V1.

After start debuging,GDB give this error.

C:\Program Files (x86)\Sysprogs\VisualGDB\vgagent.exe C:\SysGCC\xtensa-lx106-elf\esp8266-bsp\openocd\bin\openocd.exe -f interface/stlink-v1.cfg -f target/esp8266.cfg

Error: Debug adapter doesn’t support ‘jtag’ transport
embedded:startup.tcl:21: Error:
in procedure ‘script’
at file “embedded:startup.tcl”, line 60
in procedure ‘transport’ called at file “target/esp8266.cfg”, line 3
in procedure ‘ocd_bouncer’
at file “embedded:startup.tcl”, line 21

All JTAG connections are OK. Power is OK. I use ESP12Q module. GPO15 pin connected to GND by 2K resistor. CPO0 and GPIO2 connected to VCC by 10K resistors.

Detect button in “Debug Settings” find ST-Link V1.0 device.

Any ideas?

Hi,

The ST-Link programmer uses a special high-level interface that may be specific to ARM cores. If you are looking for an inexpensive JTAG programmer that will work with ESP8266, we would support anything that is FT2232-based (e.g. Olimex), as it essentially exposes the low-level JTAG interface to OpenOCD and does not impose any limitations.
