- recompile liblwip_gcc.a with new err_t definitions
- update espconn.h (function signature change, new function)
- add option to build lwip with debug-prefix-map
SHA512 module stored padding in PROGMEM, but would then pass the pointer
to padding into Update function which would do a memcpy. Use the same
approach as with SHA256, that is to copy padding to the stack first, and
then pass it to Update.
Every assert() includes a __FILE__ constant string to RODATA which
can be quite large as it includes the complete path as well as
the filename.
Move that string into PMEM, and update the postmortem to work with
either PMEM or RAM strings for dumping abort/assert/exception
information.
- update ssl_client_new signature
- add max fragment length negotiation support (hardcoded to 4096 bytes)
- build axtls with -f{function,data}-sections, ~1k less DRAM usage,
~3k less flash
- strip prefix from build paths in debug symbols
- Update SDK header files and libraries to SDK 2.0.0 plus 2.0.0_16_08_09
patch
- Remove mem_manager.o from libmain.a (replaced with umm_malloc)
- Disable switch from DIO to QIO mode for certain flash chips (saves
IRAM space)
- Add user_rf_cal_sector_set; it points to rf_init_data sector.
- Change the way rf_init_data is spoofed.
This is now done by wrapping spi_flash_read and returning the data we
need during startup sequence.
- Place lwip library into flash using linker script instead of section
attributes (saves IRAM space)
* Add multicast TTL to UDP and rework UdpContext
* Add limit for TCP TIME_WAIT pcbs
* Add liblwip_gcc.a
* Make the changes be backward compatible with the current xcc version
Using espota.py as a module by calling espota.main(args) was not working because the args given to main were not being passed into parser.parse_args(). I fixed this by having main pass args to the parser function, which in turn passes them to the parser object's parse_args() function.
* Use newlib libc library
This change adds libcmin.a, which is created from newlib libc by selectively removing some of the object files (mostly related to heap management).
The list of files is available in tools/sdk/lib/make_libcmin.sh. Files which are not needed are commented out.
This change adds support for various functions which were missing, like sscanf, strftime, etc.
* Fix some of the time functions
* Redirect stdout to serial
* Implement __putc_r
* Switch to custom newlib build
