We are experiencing an issue with the TRNG. Inside the driver, there is mention of a defect in function trng_ReadEntropy().
/* Dummy read. Defect workaround. * TRNG could not clear ENT_VAL flag automatically, application * had to do a dummy reading operation for anyone TRNG register * to clear it firstly, then to read the RTENT0 to RTENT15 again */
We are finding that after 1 or more reads, the peripheral starts to behave inconsistently, and cannot be used.
Is the Errata documented anywhere?, does it apply to the iMXRT1021?
