Fail to boot when enabling Ethernet usb driver

Nguyen Huu Ha

Dears,

I'm using Beagleboard rev C4 and try to configure usb Ethernet external device. So I enabled Davincom DM9601 based usb, and after that I had a 3.2 MB uImage.

Unfortunately, when booting, beagleboard stops at "starting kernel", do nothing. Moreover, I have the same problem when trying to enable USB gadget Ethernet , which also generated 3.2 Mb uImage.

Here is my log:

Beagle Rev C4

Any one know how to solve this situation? Thanks

Hi,

What are your boot args?

Please refer to below link for beaglebord rev c4 boot arguments.

Thank for reply

Here is my boot args: setenv bootargs 'console=ttyS0,115200n8 androidboot.console=ttyS0 mem=256M root=/dev/mmcblk0p2 rw rootfstype=ext3 rootdelay=1 init=/init ip=off omap_vout.vid1_static_vrfb_alloc=y vram=8M omapfb.vram=0:8M omapdss.def_disp=dvi omapfb.mode=dvi:800x480MR-16@60'

It works fine with uImage no Ethernet driver, I do not figure out what's wrong with my new uImage

Correct bootargs for beagle board are

setenv bootargs 'console=ttyS2,115200n8 androidboot.console=ttyS2 mem=256M root=/dev/mmcblk0p2 rw rootfstype=ext3 rootdelay=1 init=/init ip=off omap_vout.vid1_static_vrfb_alloc=y vram=8M omapfb.vram=0:8M'

Try replacing ttyS0 -> ttyS2 in your boot arguments for Linux 2.6.32 kernel or ttyS0 -> ttyO2 for linux2.6.37 kernel.

Nothing's change, in my opinion, ttyS2 is just a port to out for console, I changed it for serial port.

I think maybe uImage size too large for loading ???

Hi,

I don't think this is a uImage size related issue.
Did you try with our pre-built Image?
You can download pre-built Image from

http://software-dl.ti.com/dsps/dsps_public_sw/sdo_tii/TI_Android_DevKit/TI_Android_GingerBread_2_3_4_DevKit_2_1/index_FDS.html

First boot with pre-built Image and then replace pre-built uImage with your uImage and try

Thank for reply, it works fine with pre-built image, I tested. I think Ethernet not supported in Rev C4 by default may be a reason.

I'll try to built other image with other drivers

Update: I have tried to build other images with some other drivers, the same problem appeared

Hi,

Now can you replace pre-built uImage with your uImage and try.
