Hello,
we have a STM32F7 interfaced to a CY62148EV30 SRAM with FMC bus.
Sometimes, when several consecutive reads are performed, a wrong value is read.
The wrong value has one or more bits at 0 instead of 1 (example: 0x52 is read instead of the correct value 0x5A).
The problem disappears if a delay is added between two reads.
The delay has to be quite long (40 dummy additions of an internal register) for the problem to be cleared.
Have anyone ever experimented this problem? or have any suggestions?
Thanks!
