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.

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

Hi,

could you write the correct commands step-by-step, please?

And here my help for the autoboot loop:

.

S - Flash Throughput, 2008 KB/s  (758742 Bytes,  377680 us)
S - DDR Frequency, 537 MHz

----> here you must bridge GND (J1) and Pin 8 (U26, the first PIN on the left side, under J1)

-----> press any key on the keyboard

Now use the following commands:

setenv autoboot 10

saveenv

Reboot (plug out and plug in)

Best regards,

Stefan
