TF-M Small Profile with Initial Attestation - Related Query

by Srinivasan, Jayashree

Hello, I have been trying to test the initial attestation feature using the regression build for a platform that we are developing. TF-M small profile has been configured, which enables symmetric key-based attestation. On running the regression tests, the TFM_NS_ATTEST_TEST_2001 testcase fails. On further debugging, I found that the static buffer that mbedtls uses for its allocation is not sufficient ( CRYPTO_ENGINE_BUF_SIZE = 0x400 in small profile). When I increase the buffer size to 0x500, the testcase passes. Therefore, I wanted to know if this change needs to be adopted upstream or if I might be overlooking something on my end. Any leads in this regard would be helpful. Thanks, Jayashree
