config ETHERBONE
boolean "Compile Etherbone support in wrpc-sw"
help
This allows to run LM32 code that is aware of Etherbone.
You need to run a gateware file that includes Etherbone support.
If in doubt, say No.
config WRNIC
boolean "Compile White Rabbit NIC support in wrpc-sw"
help
This allows to run LM32 code that is aware of Etherbone and
NIC. You need to run a gateware file that includes Etherbone
and NIC support. This option needs ETHERBONE enabled.
If in doubt, say No.
config CMD_CONFIG
boolean "Include configuration in the output binary"
help
This options adds the "config" command to the shell, which
reports the current configuration. This adds half a kilobyte
to the binary size (100b for the code plus the .config file).
config NIC_PFILTER
depends on ETHERBONE
bool "Add packet filter rules for wr-nic"
help
When using wr-nic, the host must receive frames that are not
ptp nor etherbone ones. This adds the needed filter rules
to that effect. Such rules are not needed when no Etherbone
is there, because in that case all non-ptp frames reach the
host.
#
# This is a set of configuration options that should not be changed by
# normal users. If the "developer" menu is used, the binary is tainted.
comment "wrpc-sw is tainted if you change the following options"
config DEVELOPER
bool "Advanced configurations, only for developers"
help
The following options are new features under testing, or
special customizations not normally useful for people not
directly working on this package. Please don't use unless
you are a developer of wrpc-sw.
config RAMSIZE
depends on DEVELOPER
int "Size of the RAM in the FPGA for this program"
default 90112
help
The usual configuration for wrpc-sw is 0x16000 bytes
(i.e. 88kB = 90112 bytes) but if your project has less or
more features you may want to adjust the FPGA size and
choose your preferred value here.
config STACKSIZE
depends on DEVELOPER
int "Size of the stack area needed by this program"
default 2048
help
The linker complains if the code doesn't fit into RAM, but
we must also consider the stack, or the program will crash
at run time. (However, we have a detector for overflows).
config PRINT_BUFSIZE
depends on DEVELOPER
int "Size for the temporary output string of pp_printf"
default 128
help
This buffer is constant storage (i.e. wasted space), but it
also constraints the maximum lenght of text that can be written
in a single call to printf.
config CHECK_RESET
depends on DEVELOPER
bool "Print a stack trace if reset happens"
help
If the CPU is following a NULL pointer, the program will
be restarted. If this option is activated, the main function
detects that it is re-executed and dumps a stack trace; it
then clears the stack (for next time) and restarts again.
choice
prompt "Implementation of pp_printf"
depends on DEVELOPER
config PRINTF_XINT
bool "hex-and-int"
help
This selects a printf that can only print decimal and hex
numbers, without obeying the format modifiers. %c and %s are
supported too, and %p is equivalent to %x.
See pp_printf/README for details.
config PRINTF_FULL
bool "full"
help
This selects an implementation that supports all standard
formats with modifiers, like "%08X" and "%.5s". It costs
around 2k of compiled code more than XINT.
See pp_printf/README for details.
config PRINTF_MINI
bool "minimal"
help
This selects a printf that prints all integers as hex,
without obeying the format modifiers. %c and %s are
supported too. See pp_printf/README for details.
This is not probably what you want for wrpc-sw.
config PRINTF_NONE
bool "empty"
help
This selects a printf that prints the format string
alone and ignores all further arguments. Minimal size,
but not suited for wrpc-sw. See pp_printf/README for details.
endchoice
config PPSI
boolean
help
Select this option for the ppsi engine (now only option)
config DETERMINISTIC_BINARY
depends on DEVELOPER
boolean "Build a binary that is the same every time"
help
This option is used to #ifdef __DATE__ and __TIME__ strings
out of the compiled WRC binary. If you set it you'll get the
same binary bit-by-bit at each rebuild. I am using this
option to hack the build procedure and use a simple "diff"
between the old and new output to verify I didn't introduce
changes.
If in doubt, say No.
config UART
boolean "Use hardware uart (and/or vuart if available)"
depends on DEVELOPER
default y
help
This option selects the serial driver, connected to either
the USB socket, or "vuart" (software fifo) or both, according
to how the gateware is built.
config UART_SW
depends on DEVELOPER
default !UART
boolean "Use software uart"
help
The software uart is made up of two circular buffers. It can
be used either as an alternative to the harwdare UART or as
an addition. If the option is turned on, ppsi log messages
are routed to the software uart. The interactive wrpc shell
and diagnostics run on the hardware UART if available.
config SDB_STORAGE
default y
boolean "Use SDB to manage storage (instead of legacy eeprom code)"
help
Use SDB to manage flash and eeproms (both W1 and I2C). If not, legacy code
(eeprom only) will be selected.
config LEGACY_EEPROM
boolean
default !SDB_STORAGE

** 3.8 Apr-15-2011 Added __MICO_USER_<handler>_HANDLER__ preprocessor to
** allow customers to implement their own handlers for:
** DATA_ABORT, INST_ABORT
**
** 3.1 Jun-18-2008 Added __MICO_NO_INTERRUPTS__ preprocessor
** option to exclude invoking MicoISRHandler
** to reduce code-size in apps that don't use
** interrupts
**
** 3.0 Mar-25-2008 Added Header
