Specifications

hal.enable_sopc_sysid_check
• Identifier: none
• Type: Boolean assignment
• Default Value: 1
• Destination File: public.mk
• Description: Enables system ID check. If a System ID component is connected to the processor
associated with this BSP, the system ID check is enabled in the creation of command-line arguments to
download an .elf file to the target. Otherwise, system ID and timestamp values are left out of
public.mk for the application makefile download-elf target definition. With the system ID check
disabled, the Nios II EDS tools do 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. Altera strongly recommends leaving hal.enable_sopc_sysid_check
enabled. This setting is exposed to support rare cases in which FPGA logic resources are in extremely
short supply. When the system ID check is disabled, the software is unable to detect whether the
software is running on the correct hardware version. This situation can lead to subtle errors that are
difficult to diagnose.
• Restriction: none
hal.log_port
• Identifier: LOG_PORT
• Type: Unquoted string
• Default Value: none
• Destination File: system.h
• Description: Slave descriptor of debug logging character-mode device. If defined, it enables extra
debug messages in the HAL source. This setting is used by the Altera logging functions.
hal.log_flags
• Identifier: ALT_LOG_FLAGS
• Type: Decimal Number
• Default Value: 0
• Destination File: public.mk
• Description: The value is assigned to ALT_LOG_FLAGS in the generated public.mk. Refer to
hal.log_port for further details. The valid range of this setting is -1 through 3.
hal.stderr
• Identifier: STDERR
• Type: Unquoted string
• Default Value: none
• Destination File: public.mk
• Description: Slave descriptor of STDERR character-mode device. This setting is used by the
ALT_STDERR family of defines in system.h.
