Last Armbian buster legacy from download area now is running too without SPI. I have copy the boot partition (skip 64 sectors) from image piter75 to the buster legacy image. best regards BrUser

Yes, your image does boot well. Great! Can I dd boot to other new current armbian images or legacy? What is the start sector and the end? Thanks a lot, BrUser

Hello, I have a Rock Pi 4B 4GB rev. 1.3 without SPI-Flash. Now all newer Armbian-Images does not boot from SD-Card. With old U-Boot, for example June 15 I can boot from SD all new images on nvme, USB and SD. Maybe with new SPI-Boot we have lost to boot without SPI? The complete serial out is: Please can you help me to find the reason? Thanks a lot, BrUser

Two month before i have tested same device with same SATA, DVBT-Stick, power-supply, energymeter. Today is very hot. Maybe it was all time at limit. Mainline is OK. I have used R1 for 5-port managed switch and wifi-bridge. Device is running 24h/day and most time it does nothing (except WIFI and switch), only take power. Unfortunly wireshark is very slow compared with legacy kernel and if I want to use quiccly webbrowser I must start my PC. Thats why I want to have hardware acceleration. In switch driver module B53_common.c I hope to activate local link layer like mainline. Then R1 for me is near perfect for this. OK, audio goes not over HDMI and second USB does not work.

Hi Igor, many, many thanks, now legacy Debian works. Possible there is a new thermal issue or wrong detection bug. Only after reboot to desktop, 5 seconds later linux shoutdown, power off. If I wait 2 minutes then desktop starts normal. This effect I have not with older legacy images with hardware acceleration. Power is connected at battary connector, consumtion is the same at startup.

Ethernet does not working for legacy kernel + desktop, generated by Igors build tool: ARMBIAN 5.27 stable Ubuntu 16.04.2 LTS 3.4.113-sun7i. Same effect with Debian. Wifi works. In running wireshark on lamobo R1 I can see all network broadcasts (dst-MAC ff:ff:ff:ff:ff:ff) but no unicast. For example DHCP request never receive response. Not any frames from R1 seen in network. Is this behavior known, or is there a solution?

Hallo Flashbanger, R1 works with this VLAN-DSA examples more like a hardware based unmanaged switch. You can check this using filetransfer between two independ ethernet devices for example at lan3 and lan4. The system load at R1 ( top ) should be unchanged. I have seen this at green led (activity led) too, i have changed led-settings in driver B53_common.c. In dsa - driver, sorry i dont know, how to set back in unmanaged mode after initialization.

Aha, /etc/network/if-pre-up.d/dsa is called for $IFACE eth0, --all, br0, wlan0 and lo I have added at top of dsa to avoid execute more than ones. [ "$IFACE" == "eth0" ] || exit 0

I have seen, at startup my script /etc/network/if-pre-up.d/dsa is called 5 times from different tasks. 4 times with execution overlapp. This makes trouble. What can be the reason and how can I prevent the script from execution, more than one time?

Prima, seems to work with 2,2kOhm. Now driver for Mali and hardware accelerated video and all perfect for R1.

I dont know, how to deactivate eth0 or forwarding in u-boot. Settings possible available on USB (OTG) I remember. My Linux know how is low. I have problems with lldpd and lldpad, maybe it will make effects in other programs too: - lldpad can not save own port parameter if port have a dot in name. It is a feature from used parameter function. So I have renamed eth0.101 in eth0x101, ..., its a workaround. - lldpd and lldpad think eth0.101 ... is true VLAN. Information get by ioctl(). But it is not so and both servers fails with later and skip this ports. I have deactivated in lldpd/lldpad source files. But I think, it is not the correct linux way.

Possible there is misssing "ip link set br1 up" ? ... ip link set br1 up ip link set wan up ... lan1-4 and wan only need to address and set PVID and VLAN table entries. Have you checked correct work with wireshark at eth0.105? There should be never seen frames in and out from other ports. But another interesting point is the startup of R1. Have you deactivated switch forwarding in u-boot?

Yes, the same result I had some days bevor with similary initialization.

I have checked packed loss. - No packed loss at my BPiR1 board over two ports. PC--- wan BPiR1 lan4---RaspPi3. SMB-protocol, 1 GB file. ~11MB/s. In this mode there is no CPU interaction, only switch. - No packed loss over CPU. PC--- wan BPiR1---SATA. SMB-protocol, 1 GB file. ~16MB/s. - The R1 should work without VLAN in switch mode, but I dont know, how to do this over DSA or other way. - WLAN is not stable at my R1. And is not stable on RaspPi3 and not stable on Wandboard Quad (NXP).

- If you only want forward all frames from one port to each other (controled by BCM53125 dynamic MAC table) like a unmanaged switch you do not need VLAN. If you want to have a switch for LLDP or other local link layer protocol, the cpu-port need the information, from which port a telegram is coming. The BCM53125 only have the VLAN tag to insert the port information in a frame. If you give all ports the unique VLAN 1, they have all the same source tag. Same problem with router over wan port. This needs different port VLAN ID too, to address the frames from cpu port to wan port and lan to cpu port and so on. - Chips VLAN filtering is enabled, maybe in U-Boot not, because I have seen, all packets are forwarded to all ports for some seconds. - Loss of telegrams inside Linux you can try to watch with snmp statistic over all layers. - VID 1 is set initial by driver, I think to avoid forwarding from each port to other. I have removed VID 1 all times because I was not able to read back all switch internal settings ( VLAN table entries forward map, ... ). Loss of packets I will check here too. If I put my init commands in DSA-file, then switch starts strange. Can you try to put all after startup in root shell to compare?

Me again. Wifi-Problem found: - Wifi network must be deactivated in Network Manager. In case of BPI Ubuntu Xenial Desktop click on Network Icon right top corner and remove select of "Funknetzwerke aktivieren" - sudo rfkill list - sudo rfkill unblock 0 to unblock Soft blocked phy0: Wireless LAN Before I have tried some hostapd, maybe they works. At least I had installed this: https://github.com/igorpecovnik/hostapd using root: apt install pkg-config cd ~ git clone https://github.com/igorpecovnik/hostapd chmod +x ./hostapd/go.sh cd hostapd # Now it takes 15 minutes: ./go.sh # hostapd.conf taken from # ~/hostapd/hostapd.conf/hostapd.conf Regards, Albrecht

Now the simple 5-port switch function works with this initialization below. My understandig for the switch function is: The BCM53125 can only distinguish the source port of an incoming telegram using different VLAN IDs, added by the ports. It is important for LLDP, RSTP, ... and Router. In this initialization sequence the VID 101, 102, 103, 104, 105 are assigned the ports lan1, lan2, lan3, lan4, wan and stored in the ports own PVID Register. The forwarding of the incoming frames to other ports and cpu port is controlled by entries in VLAN table. Each entry is indexed by VID, here the PVID. Each VLAN table entry has a bit mask with one bit for each port to forward. rfkill unblock 0 ip link set eth0 up ip link add link eth0 name eth0.101 type vlan id 101 ip link set eth0.101 up ip link add link eth0 name eth0.102 type vlan id 102 ip link set eth0.102 up ip link add link eth0 name eth0.103 type vlan id 103 ip link set eth0.103 up ip link add link eth0 name eth0.104 type vlan id 104 ip link set eth0.104 up ip link add link eth0 name eth0.105 type vlan id 105 ip link set eth0.105 up ip link add br0 type bridge ip link set dev br0 type bridge stp_state 0 # BCM53125 ports 4, 0, 1, 2, 3 ip link set lan1 master br0 ip link set lan2 master br0 ip link set lan3 master br0 ip link set lan4 master br0 ip link set wan master br0 bridge vlan add vid 101 dev lan1 pvid untagged bridge vlan del dev lan1 vid 1 self bridge vlan add vid 102 dev lan2 pvid untagged bridge vlan del dev lan2 vid 1 self bridge vlan add vid 103 dev lan3 pvid untagged bridge vlan del dev lan3 vid 1 self bridge vlan add vid 104 dev lan4 pvid untagged bridge vlan del dev lan4 vid 1 self bridge vlan add vid 105 dev wan pvid untagged bridge vlan del dev wan vid 1 self ip link set eth0.101 master br0 ip link set eth0.102 master br0 ip link set eth0.103 master br0 ip link set eth0.104 master br0 ip link set eth0.105 master br0 ip link set br0 up ip link set lan1 up ip link set lan4 up ip link set lan2 up ip link set lan3 up ip link set wan up ifup br0 hostapd -dd /etc/hostapd/hostapd.conf The Image I have build with https://github.com/igorpecovnik/lib , complete including Desktop root@bpi:~# uname -a Linux bpi 4.10.6-sunxi #2 SMP Tue Mar 28 10:47:42 CEST 2017 armv7l armv7l armv7l GNU/Linux root@bpi:~# But some problems pending: - For LLDP in driver B53_common.c there must be reset the Bit 1 in page 0 Register 0x2F. - lldpd is not able to watch at eth0.101...eth01.105, only receives frames from eth0.

Now I have a little progress ( unfortunly back ). LLDP and other local link multicasts are dropped if switch is in unmanaged mode. After reset, managed mode seems to be set. But function b53_enable_vlan(...) in b53_common.c disables switch managed mode, and I have not found any function to enable. Maybe in DSA for BCM53125 there is no support for simple managed switch. What may be the reason why VLAN is used for WAN and router?

Hello, On my lamobo_r1 I would like to use only the 5-port switch function (and later additional WLAN-Bridge). It seems to work a little bit except the forwarding of multicasts for lldp, stp, ... There is running - Linux bpi 4.10.3-sunxi #1 SMP Wed Mar 15 17:35:56 CET 2017 armv7l armv7l armv7l GNU/Linux - configuration like this link https://github.com/igorpecovnik/lib/issues/511 - A little change in b53_common.c: struct b53_switch_chips[], BCM53125_DEVICE_ID I have added: .arl_entries = 4 The lldp-Multicast 01:80:c2:00:00:0e is set by lldpd on eth0 and br0: root@bpi:~$ bridge fdb show | grep ^01:80 01:80:c2:00:00:21 dev eth0 self permanent 01:80:c2:00:00:0e dev eth0 self permanent 01:80:c2:00:00:0e dev lan2 self static 01:80:c2:00:00:0e dev br0 master br0 permanent root@bpi:~$ At lan2 I can't see any lldp frames.

Same effect, no BPDUs. Maybe my concept is wrong. I have no manual found from BCM53125. Any have an idea and can help?
