FSMC problem with low address

When try to access to SRAM through FSMC (SRAM example from IAR 6.1) I don't see any address on  ADDRESS 7:0. Only high frequancy (> 10 MHz) peaks and splashes. With ADDRESSes 20:8 all OK. With DATA BUS all OK.  Read an Write mode - result is all the same. When disable and enable SRAM result is all the same.  Mix mode is disabled. Bus F ( Low addresses in STM32F207 ) is setted properly. Where is the problem? ( When I try to set bus F as usual  GPIO and toggle pins-  all works OK). Only when FSMC . What is the matter ? Please help !
