Hi all,

I have been trying to implement RSA on the Raspberry Pi Pico 2W RP2350 microcontroller with the Dual Cortex-M33 processor. However, I am getting stuck at wc_MakeRsaKey

RsaKey priv;
WC_RNG rng;
int ret = 0;
long e = 65537; // standard value to use for exponent

ret = wc_InitRsaKey(&priv, NULL);
printf("wc_InitRsaKey ret: %d\n", ret);
ret = wc_InitRng(&rng);
printf("wc_InitRng ret: %d\n", ret);
ret = wc_RsaSetRNG(&priv, &rng);
printf("wc_RsaSetRNG ret: %d\n", ret);
// generate 2048 bit long private key
ret = wc_MakeRsaKey(&priv, 2048, e, &rng);
printf("wc_MakeRsaKey ret: %d\n", ret);

I have tried the benchmark tests and have been unable to replicate the results at
The platform that WolfSSL tested with is slightly different:
Raspberry Pi Pico-W
ARM Cortext M0+, 125MHz
When trying to run to run bench_main from the example repository in WolfSSL:

The code gets stuck at RSA.

I saw a blog post here related to this issue:

However, I am unsure if this is the issue and, if so, how to resolve it for my Pico 2W. Any help is appreciated.
