Debug stubs is actually a table of 4-byte entries. Every entry is equal to zero or must contain meaningfull data.
|

The first entry is a service one and has the followinf format:
|
||||
- tramp_addr, 4 bytes; Address of buffer for trampoline/code. Max size is ESP_DBG_STUBS_CODE_BUF_SIZE.
|
||||
- min_stack_addr, 4 bytes; Start of the buffer for minimal onboard stack or data. Max size is ESP_DBG_STUBS_STACK_MIN_SIZE.
|
||||
- data_alloc, 4 bytes; Address of function to allocate memory on target.
|
||||
- data_free, 4 bytes; Address of function to free target memory.
|
||||
This entry is used by OpenOCD code to invoke other stub entries and allocate memory for them.
