Cerbo not connecting to vrm and external sd card installed

Hi,

I have an AC coupled systems with a Quattro and 5 200ah batteries. It has been up and stable for a year.

About 12 days ago, it stopped logging onto the VRM . I tried everything. At the time it had 2.94 firmware. I was suspicious that it had done an auto update and something had changed.

I did a full factory reset and re installed everything. .. no luck.

It had loged on for a minute or two, but then nothing.

I let the system just run with internal logging to the external SD card.

A Few days later update 3.0 was released. I upgraded to that.. nothing

I factory reset to 3.0 . During this I left my external SD card out…. And guess what.. it connects to the VRM..


It is repeatable. If I eject the SD card from the screen, it starts to log onto the VRM


I have checked the SD card in a laptop and it reads and works fine.
Has any got any ideas?

Have you tried different brand and class of SD card, and does the sd card meet the cerbo sd card port specs
