Some environment settings were posted earlier in this thread - they include the real MAC address of the devices (ethaddr= ...) preset by the manufacturer. 

If users are manually flashing their devices from 17.02 to currently 17.10 the environemt variables are lost and we should ask users to set at least their MAC address again before pressing the reset button:

Marvell>> setenv ethaddr=..:..:..:..:..:..
Marvell>> saveenv

(... until we find out how to flash SPI from linux)

Sorry. Doesn't work.

I'm using these  environment vars. (mac address is only masked in this post, not in real setting).

 

mmc rescan
env print

setenv verbosity 2
setenv boot_interface mmc
setenv image_name boot/Image
setenv fdt_name boot/dtb/marvell/armada-3720-community.dtb
setenv fdt_high "0xffffffffffffffff"
setenv rootdev "/dev/mmcblk0p1"
setenv rootfstype "ext4"
setenv verbosity "1"
setenv initrd_addr "0x1100000"
setenv initrd_image "boot/uInitrd"
setenv bootcmd 'mmc dev 0; ext4load mmc 0:1 $kernel_addr $image_name;ext4load mmc 0:1 $initrd_addr $initrd_image; ext4load mmc 0:1 $fdt_addr $fdt_name;setenv bootargs $console root=$rootdev rw rootwait; booti $kernel_addr $initrd_addr $fdt_addr'

setenv ethaddr 0F:AD:4e:xx:xx:xx
setenv eth1addr 0F:AD:4e:xx:xx:xx
setenv eth2addr 0F:AD:4e:xx:xx:xx
setenv eth3addr 0F:AD:4e:xx:xx:xx

env save

boot

 

the driver/kernel wont use those macs after reset and reboot.
I always get some randomized mac adresses for all other interfaces
every reboot.

 

If I force the mac-adress in /etc/network/interfaces manually like this
 

auto eth0
iface eth0 inet manual
hwaddress ether f0:ad:4e:xx:xx:xx

then, the interface is working with this mac.
but this is a no-go. the default mac address should
not to be set by the OS, and the mac address of the nic
should not change every reboot.

is it possible to set the mac in the kernel cmdline at least?

To use the MAC address set in the environment is not implemented yet.

Your bridge is configured with systemd-networkd - as a temporary solution you can edit the bridge 10-br0.netdev settings as shown in my earlier posting:

What needs to be done is to edit  /etc/systemd/network/10-br0.netdev to include the real MAC address of your EspressoBin:

cat /etc/systemd/network/10-br0.netdev 

[NetDev]
Name=br0
Kind=bridge
MACAddress=f0:ad:4e:xx:xx:xx

 You may need to delete any existing MAC/IP assignement of your EspressoBin in your router (to avoid any "hiccups") and then reboot your EspressoBin.

@ebin-dev

 

thank you. I know that. At least for me it is a problem if I only can set macs address
after boot process in the OS.

if you use the same image for different boards, you can't simply change those files in rootfs or
in flashed image. e.g. if you deliver the same rootfs by nfs or nbd. etc.  running script for
autogenerate keys and setting ip after well-know mac address as id.
your mac is not well-known then. that is the problem.

I'm using the vendor given unique mac address for internal autoprovisioning.
So... at first run, I won't have these settings in /etc/network or /etc/system/network..
any other config-file in my delivered rootfs can't know the mac of the board.

normally your nic gets this from bootenv/board vendor defined, before ip setting.
later you're writing those network config files and change settings.

if mac-address is changing at every reboot, I won't get such a auto configure.
even for ipv6 or other stuff it is relevant to get all well defined mac address when
initializing the nic... even at boot-time it is to late... you have to do this
before parsing or setting any config-files in rootfs.

so I have to fix autoprovisioning and get a board serial number.. send this
to an autoprov server to get a mac.. and then reset those mac address at boot-time.
but even this is a problem

in some configurations its also a severe problem, if you allow only a bunch of mac adresses...

e.g. your switch is configured to block unknown mac-adresses and setting whole port down if a
foreign mac address is detected...  as an intrusion detection.

so with changing mac adresses at every reboot (even if you change them later in system config) would mean,
those board gets disconnected from net, because it reports nonsense mac adresses first.. an the switch
denies any further access - or at least is sending false-positive intrusion detection messages.

so here - it is a no-go (at least for me), if I have only can define the mac-adresses in config-files
in the rootfs and if there ist no way to set a fix mac address already before booting the kernel to
get a clean initialization.

 

 

[FoodGenius]

sorry. my fault.

 

setenv ethaddr 0F:AD:4E:xx:xx:xx
setenv eth1addr 0F:AD:4E:xx:xx:xx
setenv eth2addr 0F:AD:4E:xx:xx:xx
setenv eth3addr 0F:AD:4E:xx:xx:xx

was a dumb typo, since
the mac vendor id of globalscale inc.  is F0:AD:4E...
so this would be the correct setting...

 

setenv ethaddr F0:AD:4E:xx:xx:xx

and with this environment setting the mac address ist also
recognized correctly without any further changes in the system.
this mac-address is set for all devices: lan0,lan01,wan,eth0,br0

unfortunately the dumb typo 0F instead of F0
also set the unicast/multicast bit... so I intiallty
thought the env setting would'nt work. rubbish.

I found this out, while doing a ugly hack as a workaround
Nevertheless... I'll share this obsolet workaround with you

1. changing environment in uboot once again... for passing
a custom kernel parameter "hackmac=F0:AD:4E:xx:xx:xx"
defined for the current board:

setenv bootcmd 'mmc dev 0; ext4load mmc 0:1 $kernel_addr $image_name;ext4load mmc 0:1 $initrd_addr $initrd_image; ext4load mmc 0:1 $fdt_addr $fdt_name; setenv bootargs $console root=$rootdev hackmac=F0:AD:4e:XX:XX:XX rw rootwait; booti $kernel_addr $initrd_addr $fdt_addr'

2. this is my changed /etc/network/interfaces  in rootfs
 

auto lo
iface lo inet loopback

auto wan
iface wan inet dhcp

auto eth0
iface eth0 inet manual

auto lan0
iface lan0 inet manual

auto lan1
iface lan1 inet manual

auto br0
iface br0 inet static
	pre-up /usr/bin/hackmac br0
	address 192.168.xxx.xxx
	netmask 255.255.255.0
	gateway 192.168.xxx.xxx
	bridge_ports lan0 lan1
	bridge_fd 0
	bridge_stp off
	dns-domain xxxxxxxxxxx
	post-up ifconfig lan0 up
	post-up ifconfig lan1 up

3. and this script  /usr/bin/hackmac for getting und setting mac-adress out of the custom kernel cmdline

#!/bin/bash

hackmac="$(tr " " "\n" < /proc/cmdline | \
grep -m1 "^hackmac=" | cut -d"=" -f2 | \
tr -dc "0-9a-fA-F:" | tr "A-F" "a-f" | head -c 17)"

[ "$#" -gt 0 ] && [ "$hackmac" != "" ] && \
ip link set dev $1 address $hackmac

exit 0

Hi there,

I am trying  to enable gpio on Espressobin Armbian and realised that the kernel that the offical Espressobin has ( 4.4.8) , is different from the current armbian ( I might be wrong ) and therefore I need a guide in how to do this. Since this requires rebuilding the kernel, I am a bit lost on how to actually rebuild and put in the correct place once done.

It is not. It's only in a slightly better shape and added functionality. Most if not all of their guides should apply here as well.

[tom_i]

@ebin-dev do you have some newer images? Or am I using last one?

The latest Armbian and flash images images can be downloaded from the EspressoBin download page (thanks to @Igor). You can choose between Debian stretch and Ubuntu xenial with legacy kernel 4.4.91. I am currently using Debian stretch (LAMP server with PHP7 and fpm enabled to serve Nextcloud services). Ubuntu xenial images work just as well.

 

There seems to be a problem with the incremental kernel patch from 4.4.91 to 4.4.92. Hopefully @Igor will find some time to solve the issue so that the legacy kernel can be updated to current 4.4.94. 

 

If you detect any issues - please report them in this forum so that they can be fixed.

 

[tom_i]

@ebin-dev ok, I've burned Debian image to my testing SD card, run `bubt flash-image-2g-1200_750_boot_sd_and_usb.bin spi usb` command, that shows me success. Then I turn it off and put that SDHC card to slot and turn on. Unfortunately it shows me this:

You need to initialise the u-boot environment. IHMO Armbian for the espressobin comes with a text file containing a suitable environment, see here for more details.

Argh.. you mean to set some setenv right? Because that flash remove all the environments. I was stupid yesterday evening. I should know it :-/

Ok thx, I'll do it today.

[tom_i]

Works gr8 now, EspressoBin 2GB is on 1200MHz up, down on 300MHz. I've switched to Debian Testing and seems it works without problem

Thx @ebin-dev & @umiddelb

[chrisf]

Does this effort include the Armada crypto hardware acceleration? Or is that already in the kernel or outside the scope of this effort and part of OpenSSL etc.?

The driver for the 5Gbps Marvell Security Engine is being developed and will be introduced into Mainline may be even this year. It is substantially different from Marvell CESA.

 

Currently only the standard crypto API is enabled in the kernel config.

Does it work for you? I found different values.

[umiddelb]

Actually yes. I've removed the partitioning information from the dts and pass it as a kernel parameter. 

[chrisf]

I've just received my espressobin board, it's a 1GB board from Amazon. 

The documentation and software on espressobin.net leaves a lot to be desired. After getting their ubuntu working and being disappointed, I'd rather take my chances with a dev build of Armbian.

 

I have a couple questions before I get started:

1) It already boots a ubuntu image just fine, do I still need to update the SPI bootloader?

2) If I do,  what's the difference between the 4 different bootloaders? Is it CPU speed and RAM speed? Is there a recommended one to use? Doesn't DVFS take over the CPU speed once cpufreq is running?

3) Which is "better", Debian or Ubuntu? I've traditionally always gone with Debian, but is there any difference in functionality or stability between the two in this case?

 

Cheers.

Updating the SPI bootloader is recommended - it will give you more functionality (i.e. enhanced PCIe support).

The difference between the 4 versions is CPU_DDR speed - recommended is 1000_800.

Both Debian and Ubuntu images work very well, there are no differences in stability - I switched to Debian stretch.

Did you reflash your bootloader? With wrong file ... This is not normal.

I flashed my 1gb board with the 1g_1000_800 bootloader. It has also crashed with the factory bootloader and the espressobin Ubuntu image. Maybe I have a defective board.

[chrisf]

I flashed 1200_750 and it's much more stable now. It's been running various benchmarks for the last hour or so without a hitch.

 

Seems like my RAM doesn't like running at 800MHz or the DDR timings are a little too aggressive.

[hochuli]

Mine is crashing once warm/hot (less than 10 minutes usually).  I've tried both 1000_800 and 600_600 with identical results:

 

Any ideas?

Now I just tried 1200_750.  Still running at close to an hour. 

 

So, both the 1000_800 and 600_600 unstable with my 1G board.

[RayGannon]

I have also just received the 1 gig Espressobin board from Amazon. One of the first things I did was document the installed firmware and save the results. As received the board appears to have been loaded with 'v1.2(release):armada-17.02.0' The processor and DDR speeds were listed as 'CPU    @ 1000 [MHz]' and 'DDR    @ 800 [MHz]' respectively. So I loaded the 'flash-image-1g-1000_800_boot_sd_and_usb.bin' firmware and installed armbian on a microSD card. This resulted in kernel panics within a half minute of boot every time. Installing the 800_800 version firmware has resulted in stable operation.

The flash images for the 512MB and 1GB EspressoBin were baked with ingredients from Marvell: DDR_Topologies (0 and 2 respctively) are predefined for those boards and they should run stable with all CPU_DDR frequencies up to at least 1000_800 (for current boards).

 

If your 512MB or 1GB EspressoBins are unstable using one of the flash images (up to the max CPU frequency promised to you), please contact GlobalScale Technologies - they should sort it out.

 

As a temporary workaround you can try to switch the CPUFREQ governor from ondemand to powersave.

I don't think there is a problem with CPU frequency. To me it looks like memory frequency problems.  There are reports of 800_800 and 1000_800 being unstable, while 1200_750 is fine. I had a look at the ram chips on my board, they're MT41K256M16TW-107 parts, so should be fine at speedbin 25. Maybe the board layout is marginal, so some work and some don't, depending on the tolerance of the parts.
