thanks for the support great job. yes fstab need to be fixed along with omap-i2c timeout. dan mcgee

Dan,
I found the issue. There was a pin in conflict. The mmc2_wl12xx_init() was using one of the pins your rmii ... Jonathan Cormier

Interesting, I tried fixing my typo and it breaks ethernet.... Jonathan Cormier

thanks work great, but two questions:
1) why is the rmii2 pin mux being called from the baseboard_setup_can()?

I'm fairly certain the only difference with my patch is it doesn't mess up all the whitespace and so should cleanly a... Jonathan Cormier

Here is my version of your patch which was applied to the head of the mityarm-linux-v3.2 branch.

11:48 AM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

I based it off the mityarm-linux-v3.2 branch but also tested it using the cl_v3.2_AM335XPSP_04.06.00.07 tag that you ... Jonathan Cormier

the error index are expected, no i/o (sign) attach dan mcgee

11:45 AM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

which git tag do you use? dan mcgee

11:43 AM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

I brought it up with
# ifconfig eth0 up
# dhclient eth0
and then _scp_'d the kernel uImage file Jonathan Cormier

11:41 AM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

great, how did you test the ethernet? dan mcgee

11:39 AM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

Dan,
I compiled the 3.2 kernel for your board. The networking seems to be working for me (see below). Also the u... Jonathan Cormier

09:12 AM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

the only change was the usb cdc device. attach is our .config file dan mcgee

09:09 AM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

I would recommend that you guys sync up on your .config files for the kernel builds as well.

09:06 AM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

ok we are know on the same page. let me see what i can come up with. dan mcgee

09:04 AM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

Yes, but you had suggested I test this on our devkit which we don't have such a pic. Jonathan Cormier

09:03 AM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

on the board is a pic that is connected to /dev/ttyACM0 dan mcgee

09:01 AM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

What I meant was that we don't have a physical usb device that identifies itself as /dev/ttyACM0. Jonathan Cormier

08:59 AM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

in the config menu dan mcgee

08:59 AM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

when you build the kernel add a usb cdc acm device. dan mcgee

08:54 AM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

Dan, I don't have a /dev/ttyACM0 device. The only one i have is attached to your board. I'm currently trying to ge... Jonathan Cormier

08:52 AM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

you can test this by running the usb_test /dev/ttyACM0 dan mcgee

08:25 AM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

I had meant that I pulled the patch from the 3.2 branch into the 3.1 branch where you already had ethernet working. ... Jonathan Cormier

07:35 PM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

i ran the patch on your mityarm board. I found the usb to be unstable, ethernet works. dan mcgee

06:19 PM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

what does this patch address? in the 3.2 kernel the usb works great. the rmii2 ethernet is the problem. dan mcgee

06:12 PM Software Development: RE: Ethernet RMII2 working in u-boot, but not kernel

downloading now, the wait on /dev/mmcblk.... is do to the gpio.cd and gpio.wp should be set to -EINVAL. dan mcgee
