Restrictions:none

Setting Name:altera_avalon_jtag_uart_driver.enable_small_driver
Identifier:ALTERA_AVALON_JTAG_UART_SMALL
Default Value:false
Value:false
Type:BooleanDefineOnly
Destination:public_mk_define
Description:Small-footprint (polled mode) driver
Restrictions:none

Setting Name:hal.dfl_start_address
Identifier:INTEL_FPGA_DFL_START_ADDRESS
Default Value:-1
Value:-1
Type:DecimalNumber
Destination:system_h_define
Description:Start address of DFL for DFL walker to read.
Restrictions:If hal.use_dfl_walker is false, this setting is ignored; If hal.use_dfl_walker is true, this setting must match the base address of the DFL ROM instance that specifies the system.

Setting Name:hal.enable_c_plus_plus
Identifier:none
Default Value:1
Value:1
Type:Boolean
Destination:none
Description:Enable support for a subset of the C++ language. This option increases code footprint by adding support for C++ constructors. Certain features, such as multiple inheritance and exceptions are not supported. If false, adds -DALT_NO_C_PLUS_PLUS to ALT_CPPFLAGS in public.mk, and reduces code footprint.
Restrictions:none

Setting Name:hal.enable_clean_exit
Identifier:none
Default Value:1
Value:1
Type:Boolean
Destination:none
Description:When your application exits, close file descriptors, call C++ destructors, etc. Code footprint can be reduced by disabling clean exit. If disabled, defines ALT_NO_CLEAN_EXIT and adds -D'exit(a)=_exit(a)' to compile options.
Restrictions:none

Setting Name:hal.enable_exit
Identifier:none
Default Value:1
Value:1
Type:Boolean
Destination:none
Description:Add exit() support. This option increases code footprint if your "main()" routine does "return" or call "exit()". If false, defines ALT_NO_EXIT and reduces footprint.
Restrictions:none

Setting Name:hal.enable_instruction_related_exceptions_api
Identifier:ALT_INCLUDE_INSTRUCTION_RELATED_EXCEPTION_API
Default Value:false
Value:false
Type:BooleanDefineOnly
Destination:system_h_define
Description:Enables API for registering handlers to service instruction-related exceptions. Enabling this setting increases the size of the exception entry code.
Restrictions:These exception types can be generated if various processor options are enabled, such as the MMU, MPU, or other advanced exception types.

Setting Name:hal.enable_lightweight_device_driver_api
Identifier:ALT_USE_DIRECT_DRIVERS
Default Value:false
Value:false
Type:BooleanDefineOnly
Destination:public_mk_define
Description:Enables lightweight device driver API. This reduces code and data footprint by removing the HAL layer that maps device names (e.g. /dev/uart0) to file descriptors. Instead, driver routines are called directly. The open(), close(), and lseek() routines will always fail if called. The read(), write(), fstat(), ioctl(), and isatty() routines only work for the stdio devices. If true, defines ALT_USE_DIRECT_DRIVERS.
Restrictions:The Altera Host and read-only ZIP file systems can't be used if hal.enable_lightweight_device_driver_api is true.

Setting Name:hal.enable_reduced_device_drivers
Identifier:ALT_USE_SMALL_DRIVERS
Default Value:false
Value:false
Type:BooleanDefineOnly
Destination:public_mk_define
Description:Certain drivers are compiled with reduced functionality to reduce code footprint. Not all drivers observe this setting. The altera_avalon_uart and altera_avalon_jtag_uart drivers switch from interrupt-driven to polled operation. CAUTION: Several device drivers are disabled entirely. These include the altera_avalon_cfi_flash, altera_avalon_epcs_flash_controller, and altera_avalon_lcd_16207 drivers. This can result in certain API (HAL flash access routines) to fail. You can define a symbol provided by each driver to prevent it from being removed. If true, defines ALT_USE_SMALL_DRIVERS.
Restrictions:none

Setting Name:hal.enable_runtime_stack_checking
Identifier:ALT_STACK_CHECK
Default Value:false
Value:false
Type:BooleanDefineOnly

Type:Boolean
Destination:none
Description:Enables the alt_load() facility. The alt_load() facility copies data sections (.rodata, .rwdata, or .exceptions) from boot memory to RAM. If true, this setting sets up the VMA/LMA of sections in linker.x to allow them to be loaded into the .text memory.
Restrictions:This setting is typically false if an external bootloader (e.g. flash bootloader) is present.

Setting Name:hal.linker.enable_alt_load_copy_exceptions
Identifier:none
Default Value:0
Value:0
Type:Boolean
Destination:none
Description:Causes the alt_load() facility to copy the .exceptions section. If true, this setting defines the macro ALT_LOAD_COPY_EXCEPTIONS in linker.h.
Restrictions:none

Setting Name:hal.linker.enable_alt_load_copy_rodata
Identifier:none
Default Value:0
Value:0
Type:Boolean
Destination:none

Default Value:none
Value:none
Type:UnquotedString
Destination:none
Description:Preprocessor macros to define. A macro definition in this setting has the same effect as a "#define" in source code. Adding "-DALT_DEBUG" to this setting has the same effect as "#define ALT_DEBUG" in a souce file. Adding "-DFOO=1" to this setting is equivalent to the macro "#define FOO 1" in a source file. Macros defined with this setting are applied to all .S, .c, and C++ files.
Restrictions:none

Setting Name:hal.make.cflags_optimization
Identifier:none
Default Value:-O2
Value:-O2
Type:UnquotedString
Destination:makefile_variable
Description:This setting defines the flags used by the compiler for CMAKE_BUILD_TYPE=Release. "-O0" = no optimization,"-O2" = "normal" optimization, etc. "-O0" is recommended for code that you want to debug since compiler optimization can remove variables and produce non-sequential execution of code while debugging.
Restrictions:none

Setting Name:hal.make.cflags_undefined_symbols
Identifier:none
Default Value:none
Value:none
Type:UnquotedString
Destination:none
Description:Preprocessor macros to undefine. Undefined macros are similar to defined macros, but replicate the "#undef" directive in source code. To undefine the macro FOO use the syntax "-u FOO" in this setting. This is equivalent to "#undef FOO" in a source file. Note: the syntax differs from macro definition (there is a space, i.e. "-u FOO" versus "-DFOO"). Macros defined with this setting are applied to all .S, .c, and C++ files.
Restrictions:none

Setting Name:hal.make.cflags_user_flags
Identifier:none
