SLCR registers are not locked upon completion of the BootROM (when the BootROM gives control to the FSBL). Leaving the SLCR registers unlocked exposes them to being accidentally overwritten.
Impact: | Trivial. There is no functional impact. |
Work-around: | Users can lock the SLCR registers early in the FSBL by writing 0x767B to the SLCR.SLCR_LOCK register. |
Configurations Affected: | All. |
| Device Revision(s) Affected: | Refer to (Xilinx Answer 47916) - Zynq-7000 Design Advisory Master Answer Record |
