Description: | Small-footprint (polled mode) driver
Restrictions: | none

Setting Name: | hal.custom_newlib_flags
Identifier: | CUSTOM_NEWLIB_FLAGS
Default Value: | none
Value: | none
Type: | UnquotedString
Destination: | public_mk_define
Description: | Build a custom version of newlib with the specified space-separated compiler flags.
Restrictions: | The custom newlib build will be placed in the <bsp root>/newlib directory, and will be used only for applications that utilize this BSP.

Setting Name: | hal.enable_c_plus_plus
Identifier: | ALT_NO_C_PLUS_PLUS
Default Value: | 1
Value: | 1
Type: | Boolean
Destination: | public_mk_define
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: | ALT_NO_CLEAN_EXIT
Default Value: | 1
Value: | 1
Type: | Boolean
Destination: | public_mk_define
Description: | When your application exits, close file descriptors, call C++ destructors, etc. Code footprint can be reduced by disabling clean exit. If disabled, adds -DALT_NO_CLEAN_EXIT to ALT_CPPFLAGS -D'exit(a)=_exit(a)' in public.mk.
Restrictions: | none

Setting Name: | hal.enable_exit
Identifier: | ALT_NO_EXIT
Default Value: | 1
Value: | 1
Type: | Boolean
Destination: | public_mk_define
Description: | Add exit() support. This option increases code footprint if your "main()" routine does "return" or call "exit()". If false, adds -DALT_NO_EXIT to ALT_CPPFLAGS in public.mk, and reduces footprint
Restrictions: | none

Setting Name: | hal.enable_gprof
Identifier: | ALT_PROVIDE_GMON
Default Value: | 0
Value: | 0
Type: | Boolean
Destination: | public_mk_define

Setting Name: | hal.enable_instruction_related_exceptions_api
Identifier: | ALT_INCLUDE_INSTRUCTION_RELATED_EXCEPTION_API
Default Value: | false
Value: | true
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: | 0
Value: | 0
Type: | Boolean
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, adds -DALT_USE_DIRECT_DRIVERS to ALT_CPPFLAGS in public.mk.

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_mul_div_emulation

Default Value: | 0
Value: | 0
Type: | Boolean
Destination: | public_mk_define
Description: | Adds code to emulate multiply and divide instructions in case they are executed but aren't present in the CPU. Normally this isn't required because the compiler won't use multiply and divide instructions that aren't present in the CPU. If false, adds -DALT_NO_INSTRUCTION_EMULATION to ALT_CPPFLAGS in public.mk.
Restrictions: | none

Setting Name: | hal.enable_reduced_device_drivers
Identifier: | ALT_USE_SMALL_DRIVERS
Default Value: | 0
Value: | 0
Type: | Boolean
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, adds -DALT_USE_SMALL_DRIVERS to ALT_CPPFLAGS in public.mk.

Restrictions: | none

Setting Name: | hal.enable_runtime_stack_checking
Identifier: | ALT_STACK_CHECK
Default Value: | 0
Value: | 0
Type: | Boolean
Destination: | public_mk_define
Description: | Turns on HAL runtime stack checking feature. Enabling this setting causes additional code to be placed into each subroutine call to generate an exception if a stack collision occurs with the heap or statically allocated data. If true, adds -DALT_STACK_CHECK and -fstack-limit-register=et to ALT_CPPFLAGS in public.mk.
Restrictions: | none

Setting Name: | hal.enable_sim_optimize
Identifier: | ALT_SIM_OPTIMIZE
Default Value: | 0
Value: | 0
Type: | Boolean
Destination: | public_mk_define
Description: | The BSP is compiled with optimizations to speedup HDL simulation such as initializing the cache, clearing the .bss section, and skipping long delay loops. If true, adds -DALT_SIM_OPTIMIZE to ALT_CPPFLAGS in public.mk.
Restrictions: | When this setting is true, the BSP shouldn't be used to build applications that are expected to run real hardware.

Setting Name: | hal.enable_small_c_library
Identifier: | none
Default Value: | 0
Value: | 0
Type: | Boolean
Destination: | public_mk_define
Description: | Causes the small newlib (C library) to be used. This reduces code and data footprint at the expense of reduced functionality. Several newlib features are removed such as floating-point support in printf(), stdin input routines, and buffered I/O. The small C library is not compatible with Micrium MicroC/OS-II. If true, adds -msmallc to ALT_LDFLAGS in public.mk.
Restrictions: | none

Setting Name: | hal.enable_sopc_sysid_check
Identifier: | none
Default Value: | 1
Value: | 1
Type: | Boolean
Destination: | public_mk_define

Description:

Enable SOPC Builder System ID. If a System ID SOPC Builder component is connected to the CPU associated with this BSP, it will be enabled in the creation of command-line arguments to download an ELF to the target. Otherwise, system ID and timestamp values are left out of public.mk for application Makefile "download-elf" target definition. With the system ID check disabled, the Nios II EDS tools will not automatically ensure that the application .elf file (and BSP it is linked against) corresponds to the hardware design on the target. If false, adds --accept-bad-sysid to SOPC_SYSID_FLAG in public.mk.

Restrictions: | The hal.linker.exception_stack_size and hal.linker.exception_stack_memory_region_name settings must also be valid. This setting must be false for MicroC/OS-II BSPs. The exception stack can be used to improve interrupt and other exception performance if the EIC is *not* used.

Setting Name: | hal.linker.enable_interrupt_stack
Identifier: | none
Default Value: | 0
Value: | 0
Type: | Boolean
Destination: | none
Description: | Enables use of a separate interrupt stack. If true, defines the macro ALT_INTERRUPT_STACK in linker.h, adds a memory region called interrupt_stack to linker.x, and provides the symbols __alt_interrupt_stack_pointer and __alt_interrupt_stack_limit in linker.x.
Restrictions: | The hal.linker.interrupt_stack_size and hal.linker.interrupt_stack_memory_region_name settings must also be valid. This setting must be false for MicroC/OS-II BSPs.
