Problem Description

When debugging with jtag, all variable values are displayed as when entering the rtos task

While working on a project, I wanted to try to go into one of the rtos tasks to see the value of a variable. However, I found that all the variables in the task showed .
The following is a screenshot of the scenario.

Expected behavior

It should have shown the value of the variable in the left display bar, like the int variable a, which should have had a value of 1 or 0

I have ever use the -O0, but it doesn't work

By the way, here is the openocd log with -d3
openocd_log.txt

After I changed the logLevel to 5 I get this full output and if it helps to find the problem then I would be very grateful.

I had this same issue, weirdly enough if you switch to Debug (-Og) in sdkconfig it works. Debug without optimization (-O0) option doesn't work. The latter seems to unset CONFIG_OPTIMIZATION_LEVEL_DEBUG and
CONFIG_COMPILER_OPTIMIZATION_LEVEL_DEBUG defines

I didn't dig too far into it but I'm guessing there's an issue somewhere down the line switching on debug option
