1. separate rom include files and linkscript to esp_rom
2. modefiy "include rom/xxx.h" to "include esp32/rom/xxx.h"
3. Forward compatible
4. update mqtt
function is called but NOT withe the same 'c' string constant that the LOG*
calls used in each module, the cache check doesn't match, so the cached
entry won't get updated. There's no point in optimizing this function
anyway because it is only called rarely.
- Fix slave initiate service discovery procedure
- Fix master re-discovery every time connection established
- Optimize service discovery char ccc write procedure
- Optimize esp_log_buffer function
- Modify default supervision timeout from 20s to 2s
This change adds two options (Debug/Release) for optimization level.
Debug enables -O0, release enables -Os and adds -DNDEBUG (which removes all assert() statements).
Debugging symbols are kept in both cases, although we may add an option to strip output file if necessary.
Also we used to define all common compiler flags in CPPFLAGS, and then appended them to CFLAGS/CXXFLAGS.
It makes it impossible to add preprocessor macros to CPPFLAGS at component level (one has to use CFLAGS/CXXFLAGS instead).
Some third party libraries are not compatible with this approach. Changed to the more common way of using these variables.
This also removes logging implementation from bootloader and replaces it
with the one provided by the log component. Some occurrences of printf
and ets_printf have been changed to ESP_LOGx APIs.
