Brick Zyxel GS1900-8 - all few seconds boot without lan

soplexie · May 22, 2022, 10:08pm

Despite following the instructions exactly, I now have boot loop.

Steps I have done.

Both partitions have been updated to the latest original zyxel firmware 2.70.
I made sure that the 1st partition is active and flashed the openwrt 21.02.3 initramfs-kernel.bin to active.
After press for boot I have no lan access (used port1 vlan 100) and therefore can not access it with ssh to flash squashfs-sysupgrade.bin.

How can I do it via serial? I don't really have a clue about serial

realtek: Add ZyXEL GS1900-8

committed 02:07PM - 14 Mar 21 UTC

The ZyXEL GS1900-8 is a 8 port switch without any PoE functionality or SFP ports…, but otherwise similar to the other GS1900 switches. Specifications -------------- * Device: ZyXEL GS1900-8 v1.2 * SoC: Realtek RTL8380M 500 MHz MIPS 4KEc * Flash: Macronix MX25L12835F 16 MiB * RAM: Nanya NT5TU128M8GE-AC 128 MiB DDR2 SDRAM * Ethernet: 8x 10/100/1000 Mbit * LEDs: 1 PWR LED (green, not configurable) 1 SYS LED (green, configurable) 8 ethernet port status LEDs (green, SoC controlled) * Buttons: 1 on-off glide switch at the back (not configurable) 1 reset button at the right side, behind the air-vent (not configurable) 1 reset button on front panel (configurable) * Power 12V 1A barrel connector * UART: 1 serial header (JP2) with populated standard pin connector on the left side of the PCB, towards the back. Pins are labelled: + VCC (3.3V) + TX (really RX) + RX (really TX) + GND the labelling is done from the usb2serial connector's point of view, so RX/ TX are mixed up. Serial connection parameters for both devices: 115200 8N1. Installation ------------ Instructions are identical to those for the GS1900-10HP and GS1900-8HP. * Configure your client with a static 192.168.1.x IP (e.g. 192.168.1.10). * Set up a TFTP server on your client and make it serve the initramfs image. * Connect serial, power up the switch, interrupt U-boot by hitting the space bar, and enable the network: > rtk network on * Since the GS1900-10HP is a dual-partition device, you want to keep the OEM firmware on the backup partition for the time being. OpenWrt can only boot off the first partition anyway (hardcoded in the DTS). To make sure we are manipulating the first partition, issue the following commands: > setsys bootpartition 0 > savesys * Download the image onto the device and boot from it: > tftpboot 0x84f00000 192.168.1.10:openwrt-realtek-generic-zyxel_gs1900-8-initramfs-kernel.bin > bootm * Once OpenWrt has booted, scp the sysupgrade image to /tmp and flash it: > sysupgrade /tmp/openwrt-realtek-generic-zyxel_gs1900-8-squashfs-sysupgrade.bin Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>

Should have all the device specific information necessary.

Thank you for the link.

After I had a serial connection I could read the following.

For me, as far as I understand it, it actually looks good. As I said, I am still of the opinion that I have flashed the right. However, it did not go...

Also I have now the with serial and tftp flashed again. After that I was just as far as before. After boot command only loop. I have then since you could see that on the 2nd partition is still the original firmware with setsys bootpartition this partition activated. After that I could boot normally with original firmware. And on the 1st partition I have then to come back to the initial state also again made the original firmware on it.
Why it may not work with openwrt I do not know.

Any improvement if you try a 22.03 image? The management VLAN has been dropped there already.

The serial header should be easily accessible and it's the only way to find out what exactly is going wrong during boot. An USB TTL adapter like this should be sufficient (don't connect the VCC pin).

Edit: looks like you got serial going, so share your boot log please. E.g. minicom can be told to log easily with -C $file.

soplexie · May 24, 2022, 2:19pm

This information I find extremely important had already seen this here

but thank you!

With the boot log and the next try to flash must unfortunately wait for the probably next weekend.
We have no replacement here and the people around me were not so enthusiastic about my attempts that for hours the internet did not work

But what I mean to have remembered that I saw in the boot log uboot version ~1.0 date 2013. If I compare that with the info here

U-Boot Version: 2.0.0.59413 (Jul 08 2015 - 09:57:29)

that would indicate an older version on my switch. Is it maybe related to that?

slh · May 24, 2022, 10:22pm

U-Boot 2011.12.39239-svn41394 (Jul 24 2013 - 09:38:34)
happened to be on mine (and work).

soplexie · May 25, 2022, 10:08am

Thanks for the information.

As so often, the problem seems to sit once again directly in front of the screen I would just like to understand what I'm doing wrong. It is not the 1st device that I have successfully flashed. I have never had problems. At least I think I'm following the instructions thoroughly. I don't know why it's going wrong this time. Let's hope for a quicker coming weekend than expected

bmork · May 25, 2022, 11:10am

I don't know if you noticed, but there is a very similar history with a Netgear GS308Tv1 here:

Makes me wonder if we've seriously messed up something. The u-boot environment you posted looked good. And so do the installation procedures described in both these threads. The GS30Tv1 story indicates that networking could be failing completely: "If I plug it into a different managed switch the port is shown as having link status of down". Which is quite unexpected. You should always at least have link on any port after a clean install.

Did you verify the link status in the other end? Not much hope playing with different configurations if the ports are dead silent...

Your boot log will hopefully help pinpoint the problem.

Borromini · May 25, 2022, 8:25pm

Wouldn't that have become apparent when people flashed master builds onto their switches? My GS1900-8HP e.g. isn't doing anything weird besides the PoE daemon being wonky. Been testing master builds on that one a few times lately. A quick glance at the 22.03 branch doesn't show much in master that wasn't backported to 22.03 either.

soplexie · May 25, 2022, 8:36pm

yes I have seen this thread already. As I understood it, the flashed openwrt has booted there and he has "only" no lan access. Mine boots every few seconds after flashing and therefore has no lan. And as i said I flashed it 2 times. 1. try via GUI, 2. try serial tftp.

I could observe this with direct connection between pc and switch and also with another switch in between. No lan after flashing on the zyxel.

I hope weekend we all know more

soplexie · May 28, 2022, 9:49am

After several unsuccessful attempts the result is frustrating.

Procedure was the following starting point.

Both partitions zyxel 2.70, switch reset.

For safety's sake new browser profile FF used.

try GUI

reset both to zyxel 2.70

try serial tftp

partition zyxel 2.60 2. partition 2.70

again 2 tries, GUI / serial tftp

and then i also tried a snapshot 22.03 with zyxel 2.60/2.70 - GUI /tftp

In short i seem to be either too stupid for this or it is simply not possible with the combination of firmware

When exporting the log file I unfortunately made a mistake. I have copied them by copy and paste from a linux machine to windoof. result --> danger of eye cancer. Sorry about that!

Ouch, that's hard to read...

But it looks like it's constantly rebooting at this point:

Without any sign of anything crashing. Almost looks like the gpio driver is pulling on a reset line while initializing... But if so, then I don't understand how that could be. I assume this code is running fine on other devices

Maybe @svanheule has an idea?

svanheule · May 28, 2022, 8:19pm

The RTL8231 driver should configure all pins as inputs, so it's strange that would trigger the hard reset. According to the info on the wiki, that would be connected to GPIO 5 on the RTL8231. The current driver does change the pins to GPIO before changing them to an input, maybe that's triggering something...

A custom build disabling gpio1 in the DTS should leave the GPIO chip alone. Maybe that's a good thing to test first.

@ soplexi , did you come any forward with this ?
