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
