Chapter 2. API Reference
CONFIG_PARTITION_TABLE_OFFSET
Offset of partition table
Found in: Partition Table
The address of partition table (by default 0x8000). Allows you to move the partition table, it gives more
space for the bootloader. Note that the bootloader and app will both need to be compiled with the same
PARTITION_TABLE_OFFSET value.
This number should be a multiple of 0x1000.
Note that partition offsets in the partition table CSV file may need to be changed if this value is set to a
higher value. To have each partition offset adapt to the configured partition table offset, leave all partition
offsets blank in the CSV file.
Default value:
•"0x8000"
CONFIG_PARTITION_TABLE_MD5
Generate an MD5 checksum for the partition table
Found in: Partition Table
Generate an MD5 checksum for the partition table for protecting the integrity of the table. The gen-
eration should be turned off for legacy bootloaders which cannot recognize the MD5 checksum in the
partition table.
Default value:
• Yes (enabled) if ESP32_COMPATIBLE_PRE_V3_1_BOOTLOADERS
Compiler options
Contains:
• CONFIG_COMPILER_OPTIMIZATION_ASSERTION_LEVEL
• CONFIG_COMPILER_OPTIMIZATION_CHECKS_SILENT
• CONFIG_COMPILER_DISABLE_GCC8_WARNINGS
• CONFIG_COMPILER_DUMP_RTL_FILES
• CONFIG_COMPILER_WARN_WRITE_STRINGS
• CONFIG_COMPILER_CXX_EXCEPTIONS
• CONFIG_COMPILER_CXX_RTTI
• CONFIG_COMPILER_OPTIMIZATION
• CONFIG_COMPILER_HIDE_PATHS_MACROS
• CONFIG_COMPILER_STACK_CHECK_MODE
CONFIG_COMPILER_OPTIMIZATION
Optimization Level
Found in: Compiler options
This option sets compiler optimization level (gcc -O argument) for the app.
• The "Default"setting will add the -0g flag to CFLAGS.
• The "Size"setting will add the -0s flag to CFLAGS.
• The "Performance"setting will add the -O2 flag to CFLAGS.
• The "None"setting will add the -O0 flag to CFLAGS.
The "Size"setting cause the compiled code to be smaller and faster, but may lead to difficulties of
correlating code addresses to source file lines when debugging.
