This anomaly applies to IC Rev. Revision 1, build codes SICA-B0A.
Symptoms
Trying to initialize the Arm® CryptoCell CC310 hardware module on nRF9160 devices using the mbedtls_platform_setup API results in undefined behavior.
Conditions
- Using samples marked nRF9160-SICA-B0A with the year <YY> number 19 and assembly week
<WW> number lower than 25 (see IC marking in nRF9160
Product Specification)
- Using an nrf_cc310_mbedcrypto library version older than 0.8.1
- Using the mbedtls_platform_setup API to initialize the CC310 hardware
Consequences
Normal operation is prevented.
Workaround
Use nrf_cc310_mbedcrypto library version 0.8.1 or higher.
