  • Type: Bug
  • Priority: Major
    On Target Test for HKDF crashes with a stack overflow. This is because the hkdf test consumes ~6KB of stsck in locsl buffers, and many Mbed OS platforms have only 4KB of stack.
    This issue is opened for tracking, and fixed by #2192


Mbed OS

mbed TLS build:
Version: 2.13.0

Expected behavior
Test to pass
Actual behavior
Tst crashes with Stack overflow
Steps to reproduce
Generate and run the HKDF On Target Test. Tested on NRF52840_DK, but it should reproduce on most Mbed OS platform, which have 4 KB stack
