All data accesses are performed on the data bus unless special machine instructions are used to read data from the instruction address space. Also, in the typical MCU, the available SRAM data memory is much smaller that the non-volatile FLASH instruction memory. So if the application requires many constant strings, the only practical solution may be to store those constant strings in FLASH memory where they can only be accessed using architecture-specific machine instructions. If ARCH_ROMGETC is defined, then the architecture logic must export the function up_romgetc(). up_romgetc() will simply read one byte of data from the instruction space. If ARCH_ROMGETC is selected, certain C stdio functions are effected: (1) All format strings in printf, fprintf, sprintf, etc. are assumed to lie in FLASH (string arguments for %s are still assumed to reside in SRAM). And (2), the string argument to puts and fputs is assumed to reside in FLASH. Clearly, these assumptions may have to modified for the particular needs of your environment. There is no "one-size-fits-all" solution for this problem. # Default settings for C library functions that may be replaced with # architecture-specific versions. config LIBC_ARCH_ATOMIC bool default n config LIBC_ARCH_MEMCHR bool default n config LIBC_ARCH_MEMCPY bool default n config LIBC_ARCH_MEMCMP bool default n config LIBC_ARCH_MEMMOVE bool default n config LIBC_ARCH_MEMSET bool default n config LIBC_ARCH_STRCHR bool default n config LIBC_ARCH_STRCHRNUL bool default n config LIBC_ARCH_STRCMP bool default n config LIBC_ARCH_STRNCMP bool default n config LIBC_ARCH_STRCPY bool default n config LIBC_ARCH_STRLCAT bool default n config LIBC_ARCH_STRLCPY bool default n config LIBC_ARCH_STRNCPY bool default n config LIBC_ARCH_STRLEN bool default n config LIBC_ARCH_STRNLEN bool default n config LIBC_ARCH_STRRCHR bool default n config LIBC_ARCH_STRCAT bool default n config LIBC_ARCH_STRNCAT bool default n config LIBC_ARCH_STRCASECMP bool default n config LIBC_ARCH_STRNCASECMP bool default n config LIBC_ARCH_STPCPY bool default n config LIBC_ARCH_STPNCPY bool default n config LIBC_ARCH_ELF bool default n config LIBC_ARCH_ELF_64BIT bool default n depends on LIBC_ARCH_ELF config LIBC_PREVENT_STRING bool default n select LIBC_PREVENT_STRING_KERNEL select LIBC_PREVENT_STRING_USER config LIBC_PREVENT_STRING_KERNEL bool default n select LIBC_PREVENT_MEMCHR_KERNEL select LIBC_PREVENT_MEMCMP_KERNEL select LIBC_PREVENT_MEMCPY_KERNEL select LIBC_PREVENT_MEMMOVE_KERNEL select LIBC_PREVENT_MEMSET_KERNEL select LIBC_PREVENT_STRCAT_KERNEL select LIBC_PREVENT_STRCASECMP_KERNEL select LIBC_PREVENT_STRCHR_KERNEL select LIBC_PREVENT_STRCHRNUL_KERNEL select LIBC_PREVENT_STRCMP_KERNEL select LIBC_PREVENT_STRCPY_KERNEL select LIBC_PREVENT_STRLCAT_KERNEL select LIBC_PREVENT_STRLEN_KERNEL select LIBC_PREVENT_STRLCPY_KERNEL select LIBC_PREVENT_STRNCASECMP_KERNEL select LIBC_PREVENT_STRNCAT_KERNEL select LIBC_PREVENT_STRNLEN_KERNEL select LIBC_PREVENT_STRNCMP_KERNEL select LIBC_PREVENT_STRNCPY_KERNEL select LIBC_PREVENT_STRRCHR_KERNEL config LIBC_PREVENT_STRING_USER bool default n select LIBC_PREVENT_MEMCHR_USER select LIBC_PREVENT_MEMCMP_USER select LIBC_PREVENT_MEMCPY_USER select LIBC_PREVENT_MEMMOVE_USER select LIBC_PREVENT_MEMSET_USER select LIBC_PREVENT_STRCAT_USER select LIBC_PREVENT_STRCASECMP_USER select LIBC_PREVENT_STRCHR_USER select LIBC_PREVENT_STRCHRNUL_USER select LIBC_PREVENT_STRCMP_USER select LIBC_PREVENT_STRCPY_USER select LIBC_PREVENT_STRLCAT_USER select LIBC_PREVENT_STRLEN_USER select LIBC_PREVENT_STRLCPY_USER select LIBC_PREVENT_STRNCASECMP_USER select LIBC_PREVENT_STRNCAT_USER select LIBC_PREVENT_STRNLEN_USER select LIBC_PREVENT_STRNCMP_USER select LIBC_PREVENT_STRNCPY_USER select LIBC_PREVENT_STRRCHR_USER config LIBC_PREVENT_MEMCHR bool default n select LIBC_PREVENT_MEMCHR_KERNEL select LIBC_PREVENT_MEMCHR_USER config LIBC_PREVENT_MEMCHR_KERNEL bool default n ---help--- Prevent any implementation of the libc memchr from being built and linked in the kernel, including NuttX's software-defined version of the libc memchr or any other architecture-specific version of it.
