LAN 9514 Drivers

[Shiva Thrishul]

Did anyone code device drivers for LAN 9514 controller without basing
any OS????

[Gerald Coley]

First you will need to run a USB stack with no OS. Then you can communicate with the LAN9514 over the USB. Drivers can be obtained from SMSC, the company that makes the LAN9514.

In that case, tftpboot is possible on beagleboard-xm ??

Thanks in advance,

[Maxim Podbereznyy]

I think u-boot supports only USB-HUB feature of LAN9514

yes with these patches :
http://patchwork.ozlabs.org/patch/100186/
http://patchwork.ozlabs.org/patch/100187/
http://patchwork.ozlabs.org/patch/100185/
http://patchwork.ozlabs.org/patch/99955/
http://patchwork.ozlabs.org/patch/99956/
(a better version of the last one will come in a few days).

Hi again,

and you may also need to patch ehci_hcd_stop in beagle.c (without this, here
display doesn't work when bootling the rowboat kernel) :
@@ -346,9 +348,25 @@ int board_mmc_init(bd_t *bis)
/* Reset is needed otherwise the kernel-driver will throw an error. */
int ehci_hcd_stop(void)
{
pr_debug("Resetting OMAP3 EHCI\n");
omap_set_gpio_dataout(GPIO_PHY_RESET, 0);
writel(OMAP_UHH_SYSCONFIG_SOFTRESET, OMAP3_UHH_BASE + OMAP_UHH_SYSCONFIG);
+ /* disable USB clocks */
+ sr32(&prcm_base->iclken_usbhost, 0, 1, 0);
+ sr32(&prcm_base->fclken_usbhost, 0, 2, 0);
+ sr32(&prcm_base->iclken3_core, 2, 1, 0);
+ sr32(&prcm_base->fclken3_core, 2, 1, 0);
return 0;
}

and you also need to add this in the .h config file of your board :
+#define CONFIG_USB_HOST_ETHER
+#define CONFIG_USB_ETHER_SMSC95XX
+#define CONFIG_NET_MULTI

+#define CONFIG_CMD_NET
+#define CONFIG_CMD_PING
+#define CONFIG_CMD_NFS

So was omap3/4 EHCI support already merged into denx upstream uboot?

OMAP3 seems merged in upstream u-boot as only this 5 patches are needed to get
tftp working on BeagleBoard XM,
I'm not using OMAP4 (TI's website says : "This product is intended for
high-volume wireless OEMs and ODMs and is not available through distributors."
so there is no interest in spending time on it).

I tried them, and I get:

OMAP3 beagleboard.org # usb start
(Re)start USB...
USB: Register 1313 NbrPorts 3
USB EHCI 1.00
scanning bus for devices... cannot reset port 2!?
1 USB Device(s) found
scanning bus for storage devices... 0 Storage Device(s) found
scanning bus for ethernet devices... 0 Ethernet Device(s) found

On my xM rev C, It does work on my C5 with an apple USB ethernet dongle.

Koen

It also works on an xM rev A1, so it's the usb power thing that breaks rev C. When I say "works" I mean "get an IP, but tftp times out". But it's progress :)

How is that question related to the current thread
which is about "LAN 9514 Drivers"?

[Koen Kooi]

Sir, I want to interface an lcd and sd card on beagle with LAN 9514 thread, please send me:

1) the exact steps
2) the codes
3) blocky diagrams.

And do not shout guesses, I'm a professional.

a quick and dirty solution can be what is shown on this picture if you don't
have time to make a clean board ;-)
