I have a probleme on my potato, I can run him without a freeze and all time I need to restart him, I don’t know why but the blue led stop and my screen freeze, I use Debian, and I have a 5v 2.5A a external keyboard and a ethernet cable plug in the board
Without more logs, it’s impossible to tell whether it’s power, board, MicroSD card, temperature, or some other reason.
What is the exact state of the board when it freezes and what is the state of the LEDs?
See Libre Computer Board Debug Serial UART Connection and Setup Guide
All the led are on except the blue one, the problems arrive when I try to download app in Debian, do you know if there is some updates for the firmware or something else, I didn’t have uart cable but I sure there is another option to fix that
What is the temperature of the board when it happens? Is there a heatsink on the device?
There is no heat skin and the board is not to hot but it’s not to cold middle temp, but when I try to execute a commande like apt-get update, it’s heating
It could be a bad MicroSD card or high temperature. Without more monitoring or logs, we cannot help you.
I have a Netcat 8GB HC, and for the heat I don’t know Do you have a tool or something else ? temperature when he sleep 40°C after a command, 50°C when I have try to install apache2
