Это еще что  FMC dynamic and static bank switching Description The dynamic and static banks cannot be accessed concurrently. Workaround Do not use dynamic and static banks at the same time. The SDRAM device must be in self- refresh before switching to the static memory mapped on the NOR/PSRAM or NAND/PC- Card controller. Before switching from static memory to SDRAM, issue a Normal command to wake-up the device from self-refresh mode. This limitation will be fixed in next silicon revision.
