I always re-install my PYNQ system

Hi, there,

I have used PYNQ Z2, ZCU104, ZCU111, BUT one common thing is I always need to re-install the PYNQ system every three days. It is very annoying. It always fail to login on the jupyter system after few days after I refresh the system. And I have changed and tried a lot of type of SD card from consumer to industrial. The problem still be the same. Does anyone know how to solve it? Thank you!

Best regards,

Dear @Charlie_Meng,

Do you get any meaningful error message?

Can you login via ssh or serial port to the board when this happens?
Have you tried different web browsers?
Are the boards connected to the Internet?

Hi, Marioruiz,

Thank you for answer. Yes, I still can login via serial port, I have tried chrome and edge browsers. The board is connected to the internet or without internet, the case doesn’t change. Other people say maybe the PYNQ system’s memory control module has a little problem, when the SD card memory building block fail, the system can’t skip it. I don’t know if this is the reason.

Best regards,
Charlie

By the way, when I can’t login in the jupyter through browers, The I try to copy the files in the jupyter notebook folder via the serial port, the file has 0 memory occupation. It seems the fail broken.

This is an interesting issue, it is the first time I see it.

Does this happen even if you do not modify anything?
