Isp1362

[Altera_Forum]

Hello everybody ! 

 Does anybody manage to make the isp1362 run under uCLinux with the OTG port configure as un host port? I'm working on Cyclone3 board FPGA ALTERA DEV board.  I have took the DE2 board schematic and created a small SantaCruz board.I have change some pins connexions :  -> OTGMODE connect to a pullup 3.3V through a 4.7kOhm -> ID to pulldown through a 4.7kOhm  I have commented (as I found in the forum) every line of the function isp1362_hc_reset in isp1362-hcd.c.   Plus, I have commented those following line in the isp1362_hc_start function :   if ((chipid & HCCHIPID_MASK) != HCCHIPID_MAGIC) { pr_err("%s: Invalid chip ID %04x\n", __func__, chipid); return -ENODEV; } When I boot the board I have those lines :  usbmon: debugfs is not available driver isp1362-hcd, 2005-04-04 isp1362-hcd isp1362-hcd: ISP1362 Host Controller isp1362-hcd isp1362-hcd: new USB bus registered, assigned bus number 1 isp1362-hcd isp1362-hcd: irq 10, io mem 0x00000050 isp1362_hc_start: isp1362-hcd isp1362-hcd: ISP1362 Memory usage: isp1362-hcd isp1362-hcd: ISTL: 2 * 256: 512 @ $0000:$0100 isp1362-hcd isp1362-hcd: INTL: 16 * ( 64+8): 1152 @ $0200 isp1362-hcd isp1362-hcd: ATL : 32 * ( 64+8): 2304 @ $0680 isp1362-hcd isp1362-hcd: USED/FREE: 3968 128 usb usb1: New USB device found, idVendor=1d6b, idProduct=0001 usb usb1: New USB device strings: Mfr=3, Product=2, SerialNumber=1 usb usb1: Product: ISP1362 Host Controller usb usb1: Manufacturer: uClinux 2.6.30 isp1362-hcd usb usb1: SerialNumber: isp1362-hcd usb usb1: configuration# 1 chosen from 1 choice hub 1-0:1.0: USB hub found hub 1-0:1.0: 2 ports detected ISP1362 Host Controller, irq 10 Initializing USB Mass Storage driver... usbcore: registered new interface driver usb-storage USB Mass Storage support registered.

Does anybody manage to access to a USB stick through an ISP 1362/1761 ? Did you do it on your own board, on a DE2 Board ?

Here is my schematic. 

All the OTG signal are connected to the isp1362 interface execpt OTG_DREQ0 and OTG_DREQ1.  CLKIN is connected to a PLL output wich generate an 12MHz signal.  Question : How the Nios manage the data transfert to the isp ? they are not on the same clock domain : the isp is 12 MHz and my Nios is 120MHz ?  Thanks is advance.

--- Quote Start ---  Question : How the Nios manage the data transfert to the isp ? they are not on the same clock domain : the isp is 12 MHz and my Nios is 120MHz ?  --- Quote End ---   The NIOS example design uses several clock domains on the Avalon bus. This is said to speed up the design greatly.  You can use an Avalon bus bridge to cross a clock domain. The avalon bus at the other site of the bridge will be connected to the I/O pins with a standard appropriate bus I/O or with your own Avalon slave design.  -Michael

That's mean that the isp1362 ic and his interface (sopc component) must have the same clock ?

[Altera_Forum]

I don't need to add an delay (phase) between the 12MHz isp1362 and 12MHz FPGA ? 

 Does anybody who manage to make usb master work on the DE2 could answer me ?  thanks !

Hi all, 

Now I get this message after boot : hub 1-0:1.0: connect-debounce failed, port 1 disabled  Does anybody got ideas ?

[Altera_Forum]

After re-reading the ISP1362 documentation I've understood that the FPGA-ISP bus is an asynchronous bus. That the reason why the ISP can run at 12MHz (external clock, internal : 48MHz) and the FPGA on other clock domain (100 MHz for my design). 

I've try to make the USB Host up and running on the DE2, however, I didn't manage does anybody got an idea ?  The DMESG is   uClinux/Nios II Built 1 zonelists in Zone order, mobility grouping off.
