Arcadyan VRV9510KWAC23 (Livebox Next) - Help to: Installing OpenWrt - Serial Console / UART

Installing and Using OpenWrt
1

Hi everybody¡
It is my very firts time.
I am tryinto to performing OEM backup and installing OpenWrt - Serial Console / UART.
Device: VRV9510KWAC23

I am using this wiki: https://openwrt.org/toh/arcadyan/vrv9510kwac23#performing_a_backup
I am no able to make ir work. I am blocked in "1. Launching U-Boot via UART"

Steps I did:

  • I set ip4 to 192.168.1.2/255.255.255.0/192.168.1.1
  • I connected the PC (Windows 10) to the router via eth using the port4 on the device
  • I have connected TX RX and GND correctly to TTL to USB adapter
  • After that, I press "connect" with serial via putty using COM18/115200/8n1
  • After that I used NAND flash hack and I pressed On button on the Livebox (https://openwrt.org/toh/arcadyan/vrv9510kwac23#nand_flash_hack), so, During boot, shortcircuit pins 8&9.
  • I get this on putty:

  • In addition, I opened tptpd64 whith server interfaces with 127.0.0.1
  • I also tried 192.168.1.1

What am I doing wrong?

Please help with the concrect steps to perform OEM backup and installing OpenWrt - Serial Console / UART.
Thanks in advance

I get working it:

ROM VER: 1.1.4
CFG 02
UART

Anybody knows how to continue with this?:
"Upload the U-Boot RAM image using your prefered serial console tool (Dump file/Send file option). This will take a minute or so. Once the upload is completed, you will see U-Boot launched" (https://openwrt.org/toh/arcadyan/vrv9510kwac23#launching_u-boot_via_uart)

4

you posted the answer to your own question.

"preferred serial console tool (Dump file/Send file option)"

5

I have try putty, tera terms...tftpd64 and I don't know how to proceed to upload u-boot.asc.

Could you explain me howto do it, please?

6

cat u-boot.asc > /dev/ttyUSB0.
If you're on Windows, copy /b u-boot.asc com1:, or whatever com port you're using.

7

Thank you for your answer.

I have two problems.

  1. when I get *, I cannot write anything on the terminal. Is there any way to write there?

*ROM VER: 1.1.4
CFG 02
UART

  1. The u-boot.asc content is online in a URL. Should I download it? How? Should I copy/paste the content and create a file in notepad++ whith . asc extension?

Thank you. I hope I get it.

8

You do need to close the serial console (so GNU screen, putty or whatever you're using), as that's keeping the serial port busy.

9

Yes, the file needs to be DL:ed.

wget ?
Right click link in browser ?

The extension has no relevance, feel free to change .asc to .poop if you'd like.

10

OK!!
If I close putty, where should I write the command in Windows. On the shell?

11

yes, in CMD....

12

Thank you. I will try ASAP

I get this error on win10

You need to read what people write you ...

And you're in PS, not CMD, dunno if it matters though.

15

I did.
I connect serial via putty to activate UART (shortcircuit pins 8 and 9)
I close Putty
I use CMD with: copy /b u-boot.asc com21
I get the error.

I am trying to do as you told me

16

ohh sorry Shell... not CMD

17

No, you didn't.

18

I tryed both

19

Well, syntax matters...
