How to implement Reboot for StratixIIs60ES ?

aqura:

Ran into this myself today.

I am using the Cyclone II 2C35 Dev board. The documantation states that the flash_byte_n line is tied low. This puts the flash in eight bit mode. So, in altera_avalone_am29lv065d_flash.c I added:

# define CYGNUM_FLASH_16AS8 (1)

You need to add a device descriptor in the following file ( ignore my project path):

c:\projects\pmod\software\ecos\romram_install\include\cyg\io\flash_amxxxxx_parts.inl

# if CYGNUM_FLASH_WIDTH == 8

.

.

.# ifdef CYGHWR_DEVS_FLASH_AMD_AM29LV128

{ // AM29LV128

long_device_id: true,

device_id : FLASHWORD(0x7e),

device_id2 : FLASHWORD(0x12),

device_id3 : FLASHWORD(0x00),

block_size : 0x10000 * CYGNUM_FLASH_INTERLEAVE,

block_count: 256,

device_size: 0x1000000 * CYGNUM_FLASH_INTERLEAVE,

base_mask : ~(0x1000000 * CYGNUM_FLASH_INTERLEAVE - 1),

bootblock : false,

banked : false,

bufsiz : 16

}# endif

Within the configuration tool under AMD AM29XXXXX FLASH memory support:

check AMD AM29LV128 flash memory

note that AMD AM29LV065D should remain checked.

Just for grins within:

c:\project\pmon\software\ecos\romram_install\include\cyg\io\flash\flash_amxxxxx.inl

in the function: flash_query(void* data)

I added the following dia_print

// Manufacturers' code

id[0] = *(FLASH_P2V(ROM+FLASH_VendorID_Addr));

// Part number

id[1] = *(FLASH_P2V(ROM+FLASH_DeviceID_Addr));

id[2] = *(FLASH_P2V(ROM+FLASH_DeviceID_Addr2));

id[3] = *(FLASH_P2V(ROM+FLASH_DeviceID_Addr3));

diag_printf("ID = %x %x %x %x", id[0], id[1], id[2], id[3]);

If all goes well it should print ID = 01 7e 12 0

Hope this helps

gramham,

I follow the steps you write and successfully read "01 7e 12 0" back. However,

the following message shows it still can not init flash. Do you have any idea about this? Please help me, thanks.

ID = 1 7e 12 0

FLASH: driver init failed: Driver does not support device

Sorry, FLASH config exceeds available space in FIS directory
