Hello, I'm following the installation method indicated in the link below. I can see the boot process via UART, but the option to select what it indicates never appears * Open the device, connect UART and select “ 1. System Load Linux to SDRAM via TFTP.” during startup"
I'm using Linux Mint and I've already tried screen and picocom.
I have this steps already OK
Router IP: 192.168.1.1
TFTP server IP: 192.168.1.100
TFTP file name: 7531.bin
Thanks for any help.
does anything appear ?
I can see all the boot process by UART but i don't get any prompt to choose that option.
Note: It's my first time flashing by UART 
Please post the output from UART up until the kernel starts.
Use the </> button when you paste the captured text.
Did you try to interrupt the boot process by spamming the router with e.g. CTRL+C repeatedly directly after power on?
Sometimes pressing enter or space repeatedly might also work.
No i didn't but today a started the process again and i got the option to choose and i did manage for flash both files. Then i did some packged updates and rebooted the router. Then the router reboot again to linksys firmware. I will try the process again from start.
Upgrading packages is not recommended:
Of course you can install packages you do not already have or use the image builder to build a specific image for you including packages you want:
Fixed. I did the flash again but after send the 7531.bin file from the server i flashed the lastest opewnwrt image 24.10.5.
Before i was flashing 24.10.4 and then upgrading by luci to 24.10.5
If your problem is solved, please consider marking this topic as [Solved]. See How to mark a topic as [Solved] for a short how-to.
Thanks!
Today i power On the router again and it started the linksys firmware again, how can i make openwrt permanent?
It is a dual boot router, OpenWRT is only present on the first partition according to the wiki.
See what happens if you change to the first boot partition, so change 2 in 1 to go to the first partition:
Maybe you have written your OpenWRT firmware to the second partition?
Edit: I think you can get the current boot partition with: fw_printenv

Well set to 2 and see what is there but probably also the OEM software.
If so it seems you did not upload the openwrt software to the first partition.
I do not have your router so just speculating
I didn't understand what you said. It's on partition 1 according to my log, right?
