mainmenu "WR PTP Core software configuration" config RAMSIZE 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 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 badly at run time. config MPRINTF boolean "Use the old mprintf implementation for printf" default y help wrpc-sw has traditionally used mprintf as its printf engine. Unfortunately, the code base has unclear copyright status, and we are now able to run pp_printf instead. Such implementation however has had little testing in wrpc-sw by now. Mprintf is scheduled to be removed in the future, as soon as pp_printf is more tested on the field. If unsure, say y for the time being. config PP_PRINTF boolean default !MPRINTF choice prompt "Implementation of pp_printf" depends on PP_PRINTF default PRINTF_XINT 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_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 equivalente to %x. 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 PRINT_BUFSIZE depends on PP_PRINTF int "Size for the temporary output string of pp_printf" default 128 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 DETERMINISTIC_BINARY 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. # The following will soon become a choice with ppsi config PTP_NOPOSIX boolean default y
