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.
