Hello sir,

I've tested the burning process on my end, and everything worked normally. I wasn't able to reproduce your issue. Could you please try replacing the download data cable? Additionally, you can refer to the successful download log I've provided to check for any error messages. Identify the relevant issues based on the errors. During the flashing process, you might experience brief USB disconnections/reconnections, which is normal.

Code: Select all

sudo dmesg | tail -n 50

Thank you for your answer.

As you describe the problem was caused by the usb disconnection/reconnection procedure during the process.
I successfully updated the firmware under Ubuntu 24.04 on my laptop by using an another usb type-c-to-a cable and checking again my procedure, also on wsl2 with usbipd-win 5.3.0.

Thank you,
