Isp1362

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

And then, I can't have access to my USB memory device.

Does anyone can help me.

Thanks in advance

    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.

    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.

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

    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 ?

    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 ?
