 This means your kernel was built seperatly from the modules..

 When you build your kernel, just also build 'make modules' and install
 them to the rootfs..

 Hi Robert,

 Thanks,
 I have compiled both modules and kernel, but still some error, without
 any information.

 root@beagleboard:/lib/modules/2.6.37/kernel/drivers/usb/gadget# insmod
 g_ether.ko
 insmod: error inserting 'g_ether.ko': -1 No such device

 The new boot log is below.

 Is there any idea why it fails ?

Hi,

Did anyone tried to work with the usb connector (the one that is marked as
usb otg), for ethernet with 2.6.37 ?
If not - maybe I should try use some older version for beagleboard ?

Ran

 It should be pretty obvious, it's actually telling you twice what

.Maybe debmod ?
depmod -a
then:
modprobe g_ether

I've tried that too...
Still same result.
We have another nibary which works well with g_ether, (but we don't have
the sources for that binary so it does not help a lot, except for telling
us that there is no HW failure)

What can I do ? Is it a problem in this package (TI'S PSP 04.02.00.07) ?

Thank you,

[beagleboard] ethernet gadget with beagleboard

Hello,


I have trouble using ethernet usb gadget driver on the beagleboard 
(omap3530).

I am using SDK 4.2.0.7 for the kernel, I've compiled it with beaglebpoard 
config, so everything is expected to work as required on this EVM.

I have compiled both kernel and modules with ethernet gadget module 
enabled, but on trying to insmod the driver, I get the following;

Did anyone encounter such failure ?

 Hello,


 I have trouble using ethernet usb gadget driver on the beagleboard
 (omap3530).

 I am using SDK 4.2.0.7 for the kernel, I've compiled it with beaglebpoard
 config, so everything is expected to work as required on this EVM.

 I have compiled both kernel and modules with ethernet gadget module
 enabled, but on trying to insmod the driver, I get the following;

 root@beagleboard:/lib/modules/2.6.37/kernel/drivers/usb/gadget# insmod
 g_ether.ko

 insmod: error inserting 'g_ether.ko': -1 No such device


 Did anyone encounter such failure ?

 Attached boot log.Regards,



Hi,
I suspect it is related to the following error:

Is anyone familiar with it ?

[beagleboard] bring-up failure

2015-01-14 Thread Ran Shalit



Hello,

I am trying to use the beagleboard (revD) for some testing, but I find it 
real hard to use it.

I have found some binaries which enable me to get to linux prompt, but on 
trying to compile u-boot and kernel myself it get into several failures 
when booting from SD card:

1. First I tried just to change the kernel (with the same u-boot binary - 
no change), I have compile the kernel with PSP 04.02.00.07:

*make distclean*
*make  omap3beagle_defconfig*
*make uImage*

But the kernel fail to start as following:

Starting kernel ...

Uncompressing Linux... done, booting the kernel.

Error: unrecognized/unsupported machine ID (r1 = 0x0706).

Available machine support:

ID (hex) NAME
060a OMAP3 Beagle Board

Please check your kernel config and/or bootloader.

2. next thing I tried to compile u-boot:

*make distclean*
*make omap3_beagle_config *
*make*

But Then the u-boot fail to start:

Texas Instruments X-Loader 1.5.0 (Jun 14 2011 - 22:04:07)
Beagle Rev C5
Reading boot sector
Loading u-boot.bin from mmc


U-Boot 2010.09 (Jul 21 2013 - 14:17:04)

(And there are no more printing)

I also get the same result with the pre-built binaries in the /beagle 
folder of the PSP. 

Is there something wrong with the above steps for booting from SD with 
beagleboard ?

Did anyone succeeded in running compiled u-boot/kernel with PSP 04.02.00.07 
? Should I move to older releases ?

Is it that the beagle is not the correct for use with beagleboard ? (maybe 
it is beaglebone )

I would appreciate any suggestion.

Regards,

Ran

 Those directions are just old and out-dated.. 

 https://eewiki.net/display/linuxonarm/BeagleBoard 


 Hi Robert,

Thanks for the link.
I am using the same instructions as in wiki, with PSP 04.02.00.07:

make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm distclean
make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm omap3_beagle_config  
make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm 
(by the way, in the wiki it says omap3_beagle_defconfig while it should be  
omap3_beagle_config 
 )

But The u-boot does not start on the beagleboard, using some binary I've 
found (revC4 image 
from http://elinux.org/Beagleboard:BeagleBoard#BeagleBoard_Rev_C4_Image)
Is there any idea why I have no success in bring-up of this simple board ?

Regards,
Ran
