A95X F1 (S905W) - System hangs/bricks after a few hours (v6.12 & v6.18)

[Marcos González Liste]

Device: A95X F1 TV Box SoC: Amlogic S905W OS: Armbian Linux Server (v6.12 and v6.18) & Desktop versions. Installation: To NAND/eMMC.

 

The Issue: I am deploying about 10 units. The installation to NAND goes smoothly, and the system boots correctly. However, after running perfectly for a few hours, the devices crash:

Video output goes to a black screen.

Network is dead (No SSH, No PING).

Power cycling the device does not recover the system; it remains in this "bricked" state.

 

Recovery Method: Once the device crashes, I cannot simply reinstall Armbian. I am forced to:

Flash the stock Android firmware using the USB Burning Tool.

Reinstall Armbian from scratch.

 

Troubleshooting done:

Tested on multiple units (10 different boxes).

Tested over a period of one month with various incremental updates.

Tested both Server and Desktop images.

Result remains the same: corruption/crash after a few hours of uptime.

 

¿Some help?

check you power supply and soc temps

But if that were the case, simply leaving it powered off for a while and then turning it back on should fix it, but it doesn't. As I mentioned, I have to re-flash them from scratch with Android before I can reinstall Armbian.

Additionally, the boards are completely exposed (out of the casing), with a heatsink on the SoC and proper ventilation. The power supply shouldn't be the issue either, as it is also fully ventilated.

After further testing, I found that the error also happens after shutting down the system, even with a clean shutdown. I did a CLI shutdown on a unit that had been running for two days. When I tried to turn it back on, I ran into the black screen problem.

Does this happen if you are running from an SD card also?  Or is it specific to running off of emmc?
