Did anyone successfully compile and added CP210x UART module to Debian 12 ( [a527_cubie_a5e_bullseye_beta_20250303_raw_disk image] from https://linux-sunxi.org/Radxa_Cubie_A5E) ?
CP210x UART module for Debian 12
After wrestling with Radxa’s Tina SDK and BSP repos (endless repo sync errors, missing Kconfig fragments, “+…-dirty” vermagic mismatches, 16 GB downloads, SSH/SSL auth pain), I found a far simpler, bullet-proof path:
Clone upstream Linux 5.15.147
Import your running config
Enable modules
Build only the USB-serial drivers
Install and load
and finally got it 
radxa@cubie-a5e:~$ ls -l /dev/ttyUSB*
