CFI Flash Reset Command

I'm using the NIOS HAL CFI routines to access (read/write) an AMD FLASH.

Looking at the waveforms, the HAL routines send the QUERY MODE command to the FLASH (write 0x98 to address 0x55) then proceed to get all the relevant information about the FLASH.

The problem is that when it is done with the QUERY MODE it is supposed write the RESET command or the READ ARRAY command to return the device to regular access mode. The Altera HAL writes the command value 0xFF whereas my FLASH data sheet specifies this command value as 0xF0. My AMD FLASH model doesn't recognize the 0xFF command and stays in QUERY MODE.

Who's "write"?

My FLASH is: AM29LV160D

I'm using NIOS II IDE v1.1.0

The line which specifies the command to use in the NIOS IDE is in the file altera_avalon_cfi_flash_table.c:# define READ_ARRAY_MODE (alt_u8)0xFF

Thanks,

Nathan
