This is my configuration of FlexBUS for IS61LV256AL SRAM (http://www.mouser.com/ds/2/198/61LV256AL-258426.pdf) and MK22FN512VLL12
Hi
First of all, sorry for the later reply.
Could you check the Flexbus clock frequency setting?
From the K22 reference manual, the FlexBus clock Max. frequency is 50MHz:
Please check System Clock Divider Register 1 SIM_CLKDIV1[OUTDIV3] bits value, which related to Flexbus clock frequency.
Wish it helps.
Have a great day,
Ma Hui
