This option enables the 54L CRACEN based entropy driver, based on the nrfx CRACEN CTR_DRBG
|
|
random driver.
|
|
Notes: This driver is only compatible with 54L devices, and may only be used from one processor
|
|
core. This driver cannot be used in conjunction with the nRF security PSA solution, as both
|
|
would attempt to use the CRACEN HW exclusively; When that is enabled, the PSA crypto entropy
|
|
driver should be selected instead.
