- 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)
Updating SDK libraries
After updating SDK libraries to a new version, do the following changes.
-
Remove mem_manager.o from libmain.a to use custom heap implementation
xtensa-lx106-elf-ar -d libmain.a mem_manager.o
Updating libstdc++
After building gcc using crosstool-NG, get compiled libstdc++ and remove some objects:
xtensa-lx106-elf-ar d libstdc++.a pure.o
xtensa-lx106-elf-ar d libstdc++.a vterminate.o
xtensa-lx106-elf-ar d libstdc++.a guard.o
xtensa-lx106-elf-ar d libstdc++.a functexcept.o
xtensa-lx106-elf-ar d libstdc++.a del_op.o
xtensa-lx106-elf-ar d libstdc++.a del_opv.o
xtensa-lx106-elf-ar d libstdc++.a new_op.o
xtensa-lx106-elf-ar d libstdc++.a new_opv.o
