external SRAM on a Kiel board

Hi.

I'm trying to get the basic understanding for the FSMC lib and how to use it to control an external SRAM, I’m using the ST firmware lib example (SRAM) on a Keil MCBSTM32E board.

I have read the AN2784 and every thing seems just fine. I'm using the example right out of the box.

But when I try to write to the SRAM using the FSMC_SRAM_WriteBuffer() function, the program stops in the HardFault_Handler loop and I get a IMPRECISERR error.

I haven’t included the:

FSMC_NORSRAMInitStructure.FSMC_AsyncWait = FSMC_AsyncWait_Disable;

I use STLib v 2.0.3

hope you can give me a push in the right direction, thanks
