In the i.MX6UL RM, there is a description of a fuse named "UART serial download disabled selection" at location 0x470 (bit 4).
There is not a lot more description about this fuse. In particular, how different is it from the SDP_DIABLE fuse at location 0x460 (bit 17).
Could you provide an explanation on the relative use of these 2 fuses?
Thanks

Solved! Go to Solution.
Correct, if SDP_DISABLE is set, no need to set "UART serial download disabled selection".

Hello,
"UART serial download disabled selection" relates to UART only.
SDP_DISABLE concerns both UART and USB.
Both fuses provide workarounds against the Vulnerability.

Have a great day,

So if I set SDP_DISABLE, I don't really need to set "UART serial download disabled selection" (event if it should not cause any trouble to also set "UART serial download disabled selection"), right?
Thanks.
