DE2-115: Problem - ISP1362 Does Not Work

Hi guys, 

 

I am using DE2-115 board configured with SOPC file from included DE2-115 CD (DE2_115_NIOS_DEVICE_LED). 

 

I removed all components except the following: 

- pll 

- jtag_uart 

- cpu 

- onchip_memory 

- sdram 

- clock_crossing_io 

- timer 

- sysid 

- usb 

 

I made some changes on the remaining components as below (SOPC screenshot attached):  

1. cpu 

- enable hardware divide 

- reset & exception vector: memory: sdram 

- include mmu 

- fast TLB miss exception vector: memory: onchip_memory 

- include tightly coupled instruction & data master ports 

2. onchip_memory 

- enable dual port access 

- total memory size: 1024 bytes 

3. usb 

- changed name to ISP1362

I made kernel configuration as below: 

- platform options 

=> enable MULX instruction 

=> enable DIV instruction 

- device driver 

=> SCSI device support 

=> SCSI disk support 

=> USB support 

=> Support for host-side USB 

=> USB device filesystem 

=> ISP1362 HCD support 

=> USB mass storage support 

- File Systems 

=> Ext3 journalling file system support 

=> DOS/FAT/NT Filesystems 

=> MSDOS fs support 

=> VFAT (Windows-95) fs support 

=> Native language support 

=> codepage 437 

=> NLS ISO 8859-1 

 

I successfully made the image and load into DE2-115 board, but there is where problem occurs: 

 

Condition# 1.  

If I exclude isp1362 in both sopc & kernel configuration, nios2-linux starts up normally, but with garbage characters occasionally displayed when starting up nios2-linux. 

 

Condition# 2.  

If I include isp1362 in both sopc & kernel configuration, it is downloaded to the board and verified successfully, but then just hang at there, nothing more comes out in nios2-terminal, nios2-linux fails to start up. 

 

Any advice regarding this matter? Thanks!

Hi, 

 

Your hardware meets the timing ? How about the clock phase shift for sdrams ?

Hi, 

 

Thanks for your reply. I use the default hardware timing configured in the reference design. 

 

For ISP 1362: 

 

hc (connected to data master) 

Setup: 140ns 

Read wait: 50ns 

Write wait: 50ns 

Hold: 140ns 

 

dc (connected to data master) 

Setup: 150ns 

Read wait: 150ns 

Write wait: 150ns 

Hold: 150ns 

 

I did try to change all parameter values to 100ns as described in altera wiki, but still failed. 

 

For sdram: 

 

Clock frequency: 100MHz 

Clock phase shift: -65 deg 

 

Oh yes, there is 1 more thing. If I only use Nios II without MMU, and compiled using older version of Nios II Linux, the USB works properly. 

 

Any idea regarding this situation? Thanks! ^^

Maybe the timing for sdrams is OK, and the timing for ISP 1362 will not affect the booting. But did you set the processor starting address at 0xc100000? 

 

Downloaded 4199KB in 90.1s (46.6KB/s) Verified OK Starting processor at address 0xC1000000 nios2-terminal ...... Anyway I'm making a "Try Out Example" for Terasic's tPad, and going to upload those to Altera Wiki. In those, ISP 1329 Host is working well and I can plug keyboards, mouse, USB memory and etc. successfully. Would you please wait a moment ?

MULX? did you enable this in your processor?

Hi,  

 

Kazuyasu: 

 

Well, I leave it to that one to default setting, since it usually works in this way. 

Hmm, will try on this and tell you guys about the results. ^^ 

 

ykozlov: 

 

Yup, I did. Isn't it has to be enabled if hardware divide option is enabled in Nios II processor? 

 

Thanks and regards,

I'm using the old '20080619' version sources which Wind River guys threw to Nios Wiki community.This version has many problems around mmu's macros and we can't select the main memory base address freely except 0xc0000000. Of cource, I don't know that the latest version improves these or not, but I recommend you to delete the residual offset.

MULX is 64-bit Multiply and is different from MUL. I don't think it's related to DIV. 

 

If you have an instruction enabled in your build that the processor doesn't have, you're going to run into problems.

Hi guys, 

 

Kazuyasu: 

 

I tried changing the processor starting address to 0xC1000000, but still results in the same, even sometimes it refused to load image. There are times when same configurations but just recompilation even cause kernel panic.  

 

Would you send me any SOPC design of yours on DE2-115 as reference for me? Because I did follow the same steps described in Altera Wiki but still failed~ >< 

 

ykozlov: 

 

Hmm, I disabled the hardware divide option and uncheck MULX instruction in kernel configuration menu, yet the usb still not functioning. I think this is not the one which affects the functionality of isp1362. 

 

Thanks and regards,

Hi Kazuyasu, 

 

I tried to load with your image, and seems that there's no problem with the hardware. 

Thanks for the attachment. ^^ 

 

Anyway, will refer to your configuration and compare to see where I went wrong, since you are using Quartus 9.1, and I am using version 11.0. 

 

Thanks and regards,

Hi guys, 

 

Thanks a lot for the attachment, seems working on my board, means it's no problem with the hardware.
