Compiler/RM57L843: ASYNC EMIF interface CS doesn't work

Part Number: RM57L843

Tool/software: TI C/C++ Compiler

Hi All,

I'm using the async emif interface with CS4, in the HAL Code Generator I have only selected the async interface with CS4. But when I try to make a write cycle CS doesn't go down it is still high. I also monitore the WE and two Adress bits, these signals are working?  I'm using the developement kit from TI.

I do it like this

emif_ASYNC3Init();

Ext_Async_Mem_Write2(EMIF_CS4_ADDRMAP_START, 0x66AAFF44, NO_OF_WORDS);

The function is below:

unsigned int Ext_Async_Mem_Write2(unsigned int Ext_Mem_Address_Ptr,

unsigned int Data_To_Write_Ptr,
unsigned int No_Of_32BitData)
{
unsigned short *Addr = (unsigned short *) Ext_Mem_Address_Ptr;

while(No_Of_32BitData > 0)
{

*Addr++ = Data_To_Write_Ptr;

No_Of_32BitData--;
}
}
