Topic: SRP with WOLF_CONF_MATH set to SP Cortex-M
I'm trying to prototype SRP on an STM32WB55 chip using STM32CubeIDE. I can compile my test program just fine when WOLF_CONF_MATH is set to 1 (FAST); however, in order to try to speed things up, I would like to use SP Cortex-M math. I can't get the program to compile when I set WOLF_CONF_MATH to 4. I keep getting compile errors to undefined reference to sp_submod. Is there anything special I need to do to get this to work?
I have attached my wolfSSL config file for your reference.
