I don't know about the CB1 but I do know that only the 32 bit Ratos is recommended for the Pi.

this is on my VC 3.1 400 normal. So i might need to get a 32 bit installed then. It might be to hard for the cb1. Thanks for the tips

So i guess i need to update the cb1 manually since i cant seem to find that in the ratos configurator. With the cb1. So i can maybe just SSH into it and do the update from there or? Ill try to find some guide online. Knew i had quite a hassle last time getting installed correctly

Its a loose USB connection to your motherboard or toolboard

Happens when the raspberry pi loses USB connectivity with the octopus or toolboard

That's a different error message. Lost connection vs timer too close. The latter means the MCU couldn't keep up

I thought its the same error. If I fiddle eith thr USB C going into an ebb46 toolboard, I get the timer too close error.

Mcu remains connected but connection is faulty, hugh packet loss -> timer desync

TheTik•12/24/25, 8:59 PM

Hmm, that's very interesting. With the USB protocol I wouldn't have expected that.

Its my VC 3.1 With the manta m8p and cb1. On the cb1 i have the 64bit installed witch take alof of memory having the ratos configurator in the back ground.

Here i turned it off so then it goes down to 30 % so i can use my printer still so it wont get to busy
