debug: thread_info: stack pointer is not supported for xtensa (1672f6ce) · Commits · Wenxi XU / zephyr

Xtensa does not store the stack pointers in thread objects but pushing the registers into the stack. There is no fixed location to retrieve the stack pointer so mark it as unimplemented to avoid the #warning. Fixes #38405 Signed-off-by:
