I have seen that the buffer size is defined as 50000 in wolfcrypt benchmark.c  (when using #define BENCH_EMBEDDED )

but, the buffer size is big to use on my device ( Nrf52, 64k ram )

so, my questions are..

1) what is the minimum buffer size to use the ECC with WOLFSSL_STATIC_MEMORY?

2) Is there some guide how to use the ECC on Nordic nrf52 without heap memory?
