This is makefile's for creating a wolfCrypt library using the m68k-elf-gcc toolchain and example benchmark/testwolfcrypt application linking to it. The examples and default builds where made to support a MCF5441X board.
Macros to define for use: WOLFSSL_MCF5441X /* arch settings i.e. sizeof long and endianness / WOLFSSL_NETBURNER / for use of NetBurner headers and RNG seed */
To build the wolfssl.a library (settings for wolfCrypt only by default) run "make" from the directory wolfssl-root/IDE/M68K/. By default this outputs the wolfssl.a library to be at $(NBROOT)/lib. This can be adjusted by adjusting the variable OUTPUT in Makefile.
If the macro WOLFSSL_MCF5441X is defined then wolfssl-root/wolfssl/wolfcrypt/settings.h sets the sizeof long and long long along with big endian macro.
The configuration for the build is located in wolfssl-root/IDE/M68K/user_settings.h Along with the default build there is 2 others BUILD_B (smaller resource use), and BUILD_C (faster runtime with more resource use).
RSA speeds of the builds
default: RSA 2048 public 3.333 ops/sec RSA 2048 private 0.190 ops/sec
BUILD_B RSA 2048 public 3.333 ops/sec RSA 2048 private 0.053 ops/sec
BUILD_C RSA 2048 public 7.619 ops/sec RSA 2048 private 0.276 ops/sec
###Building testwolfcryt/benchmark To build either testwolfcrypt or benchmark first build wolfssl.a, place it in $(NBROOT)/lib and then cd into the respective directory. Running "make" will then create a .s19 application that can be ran on the board.
When running either testwolfcrypt or the benchmark app the first thing they do is loop on calling RandomValid until getting a successful return. This is done in order to wait for a source of entropy. It could take several moments until completed.
