You need to retry to break autoboot.
sometimes you need a few attemps.

i prefer to read the nor with in circuit flash.

if you can save the environment you must rebuild all env vars before loading the image file.

Hi,

i got two more APX120 with a red LED bug.

tried a few other methods, this one works fine 

1. get into uboot emergency console, change bootdelay, save, reboot
2. enter uboot console, set all env variables, save, reboot, enter uboot
3. erase nand chip, tftpboot old APX.v11.0.019-2.uimage, connect APX120 to a XG 19.5.3
4. boot from memory, APX120 will boot and register with XG 19.5.3, enable APX and wait for final F/W upgrade to 11.0.021-1

No need to get root access

But with 11.0.019-2 i had a root access without any failsafe method.

Hello Juergen, 

Can you tell me where you find APX.v11.0.019-2.uimage? Or if you have it, can you provide link to download?

Hi Juergen,

Managed to find the Image (inside the Pattern Update tar). I could link the APX with the Firewall but after reboot I get an error - Volume kernel not found! and I'm back on the uboot console.

Do you have any suggestion?

Hello Juergen,

Can you post all the env variables that need to be set? I think I made some mistake there...

Hi,

this is the fw_printenv from OpenWRT (root shell from APX120).

Thanks!! Managed to fix one APX, now lets try with the second one!

Hi,
can you tell me where to get the APX.v11.0.019-2.uimage ? All pattern files I found only include the newest version 11.0.021...
Thanks Jan

Hi Jan,

You can find it on my OneDrive:

perfect, thank you

Hi,

how did you manage to get keyboard inputs in putty ? are there any options needed ? I tried different settings in putty, but I am not able to input any text, after I successfully breaked autoboot.

Thanks Jan

You need a good USB<->RS232 Adapter with 3.3V and need a few attempts to get in to uBoot CLI.

I had some trouble with a USB Hub.
The RS232 Adapter should be plugged into the backside of a PC or directly in your Notebook.

Hi,

I am already in the uBoot CLI, but I cannot input any kind of text in Putty.

I am using the red USB RS232 Adapter with 3,3V (the one, which work for other users), directly plugged into the notebook.
Are there any Putty options, which I need to set ?

No (115200,8N1)

Only use pin 2,3,4 (TX,GND,RX, may be switch TX/RX).

of course I am using already these pins and settings, but i cannot type any text

If this doesn´t work, you need to get a different USB<->RS232 Adapter.

I had some cheap from ebay, these worked fine with a lot of devices, but not with APX120.

which one are you using ?

I have a few with PL2303HX Chipset, but with Windows 11 i switched to PL2303HXD.

But, yes most of the PL2303HX are some cheap, pink models.

Thank you!!

works with a CP2102 ;-) but now I have the reboot problem as mentioned above.
Do you have also any ideas ?

Hi,

i had a few solutions, but the best was still to setup a XG firewall with a setup for AP.

Next you need to enter APX120 uboot and use these 3 steps.

(APX120) # nand erase.chip clean
(APX120) # tftpboot APX120.v11.0.019-2.uimage
(APX120) # bootm 0x84000000#config@4

After that, the APX120 boots and connects to the XG.
You need to add the APX to the XG and the XG will send a new firmware.
The APX will upgrade by itself.

Thanks to all for your help, only the following steps worked. I had to update to V 2.3.4-5 (maybe because my XG is already on SFOS 20):

1. get into uboot emergency console, change bootdelay, save, reboot
2. enter uboot console, set all env variables, save, reboot, enter uboot
3. erase nand chip, tftpboot APX.uimage (2.1.1.1)

Boot into failsafe (some tries neccessary, hit enter until root) and update with shell script (V 2.3.4-5)

cd bin
wget https://d2apih4urmzzdu.cloudfront.net/v2.3.4-5/APX.uimage
./update_image.sh APX.uimage
reboot

4. APX120 will boot and register with XG, enable APX and wait for final F/W upgrade
