openocd jtag problem [solved]

[michaelu]

Hi,
I use Sloeber, and try to debug with an OpenOCD Jtag adapter.
In Eclipse, the GDB OpenOCD Debugging Config options are

Code: Select all

-c "debug_level 3" -s d:/eclipse-sloeber/openocd-esp32/share/openocd/scripts -f interface/ftdi/openocd-usb.cfg -f board/esp-wroom-32.cfg -c "adapter_khz 1000"

When I start to debug, Eclipse pops up a "Problem Occurred" window, with details:

Code: Select all

Error in final launch sequence
Failed to execute MI command:
continue
Error message from debugger back end:
Warning:\nCannot insert breakpoint 1.\nCannot access memory at address 0x400d2674\nCannot insert breakpoint 2.\nCannot access memory at address 0x400f1aec\n

Could you please post the messages related to failure to get flash mappings (at -d3 debug level)? They might point to the source of the issue — without knowing flash layout, OpenOCD can not insert breakpoints in flash.

Sorry that I bothered you with this. I think the problem was the "adapter_khz 1000" at the end of the config options, where a 0 is missing. Also, the statement is not necessary, esp32.cfg contains an "adapter_khz 20000" statement.
