ROM: In NOR Low Latency Boot Mode, Wait Monitoring Will Not Work
1.1
Boot mode affected: NOR Low Latency (FAST_NOR)
In the NOR Low Latency Boot Mode, the pin mux configuration for the GPMC_WAIT0 is not performed by the ROM Code. As a result, a NOR Flash that needs wait pin configuration is not supported. Wait monitoring during boot should not be enabled (SYSBOOT[9] should remain 0).
This affects only NOR Low Latency Boot Mode (FAST_NOR). NOR boot is not affected by this issue.
The GPMC_OE (Output Enable ) signal is active for 833.32 ns.
If the Flash is able to receive data within 833.32 ns, FAST_NOR will work as normal.
