Hi @tjko , Thank you for this fix and all your excellent suggestions / reports. I think we should work on getting you setup as a contributor (I couldn't find one started yet). Can you email support at wolfssl dot com and reference any PR's you've put up? Also please include your location and details about your project. Thanks, |

I was testing wolfSSL on RPi Pico and Pico 2 based on RPi-Pico/CMakeLists.txt and noticed ECC key creation routine (wc_ecc_make_key()) hanging on Pico 2, but working fine on Pico (1).
I traced it down to a hang in sp_256_sqr_8(), which seems to have caused (incorrectly) set
WOLFSSL_SP_ARM_THUMB_ASM. (When compiling withWOLFSSL_SP_ARM_CORTEX_M_ASMthere is no problem on Pico 2).This updates platform detection to look for "rp2350-arm-s" instead "rp2350" in ${PICO_PLATFORM}.
