Re: xbd file for the Spartan 6 LX75T kit

Do these FLASH parameters look ok?

 

 PARAMETER C_TLZWE_PS_MEM_0 = 0

 PARAMETER C_TCEDV_PS_MEM_0 = 100000

 PARAMETER C_TAVDV_PS_MEM_0 = 100000

 PARAMETER C_THZCE_PS_MEM_0 = 20000

 PARAMETER C_THZOE_PS_MEM_0 = 15000

 PARAMETER C_TPACC_PS_MEM_0 = 25000

 PARAMETER C_TWC_PS_MEM_0 = 100000

 PARAMETER C_TWP_PS_MEM_0 = 35000

Re: xbd file for the Spartan 6 LX75T kit

The following parameter settings for the Flash memory on the S6LX75T board should work:

 

BEGIN xps_mch_emc
 PARAMETER INSTANCE = FLASH_16Mx16
 PARAMETER C_NUM_BANKS_MEM = 1
 PARAMETER C_NUM_CHANNELS = 0
 PARAMETER C_MEM0_WIDTH = 16
 PARAMETER C_MAX_MEM_WIDTH = 16
 PARAMETER C_INCLUDE_DATAWIDTH_MATCHING_0 = 1
 PARAMETER C_SYNCH_MEM_0 = 0
 PARAMETER C_TCEDV_PS_MEM_0 = 120000
 PARAMETER C_TAVDV_PS_MEM_0 = 120000
 PARAMETER C_THZCE_PS_MEM_0 = 35000
 PARAMETER C_TWC_PS_MEM_0 = 120000
 PARAMETER C_TWP_PS_MEM_0 = 120000
 PARAMETER C_TLZWE_PS_MEM_0 = 35000

What about the BYTEN pin. Is this correct?

 

In MHS:

 PORT fpga_0_FLASH_Mem_BYTEN_pin = net_vcc, DIR = O

 

In UCF:

Net fpga_0_FLASH_Mem_BYTEN_pin LOC=N9  |  IOSTANDARD=LVCMOS33; # byte mode select - high is 16-bit mode

 

I'll try your settings now. Have you been able to successfully use the parallel FLASH with SDK Flash Writer? I only get this

 

Flash Programming failed.

Setting PC with Program Start Address 0x00000000

* Performing CFI Query on the flash part(s)...*

* ERROR: In-system programmer reported an error: Unable to successfully query target part layout using CFI!

* Flashwriter terminating !

Re: xbd file for the Spartan 6 LX75T kit

when you say "should work" can you elaborate? The settings you have don't match the data sheet for the FLASH part. Have they worked on another part that you believe to be similar?
