Latest test image with SanCloud BeagleBone Black Enhanced (ethernet broken)

[Paul Carpenter]

Hi all,

I am using the BeagleBone Enhanced from SanCloud and using it for several IOT related projects. We have used the stable March build with success but we just recently added the latest LCD touch display from NewHaven. In order to get that to work, we went to the latest test image (5/14/2017) from the WiKi. It seems the onboard Ethernet connection no longer works. The 'eth0' interface is recognized and is set up as a DHCP client. It sends the IP request out and the DHCP server responds. However, it appears the BBBe's driver/firmware does not process the response. Using a static IP address doesn't work nor does the latest console or LXQT images.

Any thoughts? I know this image is a test image and I saw a note that the SanCloud BBBe needs work and more testing. I am wondering if a work-around has been found.

Thanks,

Paul

Hi Paul,

Yeah i hadn't completely finished porting all the clone boards to
u-boot overlays.

I just finished the SanCloud for you and Marc this morning.. It'll be
a few days, (kernel builders are behind as 4.12.0-rc2 is being worked
on), till i have a new out of the box image.

But to get your board working now/today, follow these 7 steps..:

**********************************************************************************
1: remove NewHaven display
2: bootup, login, disable "enable_uboot_overlays=1"

sudo sed -i -e 's:enable_uboot_overlays=1:#enable_uboot_overlays=1:g'
/boot/uEnv.txt

3: reboot (this will boot the old device tree) and ethernet should work.

4: update Device Tree's

cd /opt/source/dtb-4.4-ti/
debian@beaglebone:/opt/source/dtb-4.4-ti$ git pull

5: update U-Boot

$ cd /opt/scripts/tools/developers/
debian@beaglebone:/opt/scripts/tools/developers$ git pull
Already up-to-date.

-----------------------------
Bootloader Updated
Bootloader Recovery Complete

6: reboot and verfy U-Boot (2017.05-00002-gc0970ed183 this is today's
build that specifically add the SanCloud BBE to the u-boot overlays)

Option A: (if you have a serial cable)

**********************************************************************************

Reset Source: Power-on reset has occurred.
MMC: OMAP SD/MMC: 0, OMAP SD/MMC: 1

Board: BeagleBone Black
Model: SanCloud BeagleBone Enhanced
**********************************************************************************

Option B: (if you don't have a serial cable)

$ cd /opt/scripts/tools/
debian@beaglebone:/opt/scripts/tools$ sudo ./version.sh | grep bootloader
[sudo] password for debian:

7: Re-Enable "enable_uboot_overlays=1", shutdown, and re-install the
New HavenCape

sudo sed -i -e 's:#enable_uboot_overlays=1:enable_uboot_overlays=1:g'
/boot/uEnv.txt
sudo systemctl poweroff
