I used a regular ch340, most likely a fake. Keep in mind that the baud rate is 1500000 in both u-boot and Linux.

Updating via `apt update && apt upgrade` causes Armbian to fail to boot on the single-board computer. I'm attaching the UART logs in the file `failed_log.txt`.

To reproduce the issue (~13.11.2025-16.11.2025), simply download and flash the current `Minimal/IOT for Armbian Linux v6.12 [Debian] Debian 12 (Bookworm)` images (`https://www.armbian.com/nanopc-t4/`) and run `apt update & upgrade` on a running system, then reboot. After this, the system, regardless of whether the `SD card` or `EMMC` is used, will enter an infinite boot loop (`out` and file `failed_out.txt`).
