Help¶

This anomaly applies to IC Rev. Engineering A, build codes QKAA-AB0. This config MUST be enabled if there is a chance the code will be run on nRF5340 Engineering A. Enabling this config is safe on other nRF5340 variants, but might increase flash size. The workaround involves adding run-time checks when using the SPU, and aligning regions on 32 KiB instead of 16 KiB if they are to be locked with the SPU.
