You will need to reboot twice total, once to place the files, and again to activate the I2C.

punt!

Is it running correctly? I dont think so, my fan is still running at 100%.
Do I have to plug in a USB Stick?
I have the ArgonOne m.2 (SSD is connected by USB bridge, there is no other sd-card or stick inserted).
Rpi 4

231

Disable protection mode as mentioned

232

I even got hung up on protection mode just now :slight_smile:

233

PI 5 run on SSD m.2
I already disable protection mode
but log show below

I don’t see I2C.
no sda1 available
no sdb1 available
no mmcblk0p1 available

dtparam=i2c_vc=on
i2c already configured on nvme0n1p1. Reboot required.
dtparam=i2c_arm=on
i2c already configured on nvme0n1p1. This addon was already run during this boot and no reboot occurred.
This Configurator did it’s job. Perform a hard-power-off reboot now.

234

Worked like a charm on Pi5 with NVME.

Checked the logs, disabled protection mode, checked logs, rebooted, check logs again, last reboot, done!

Now I need to learn how to create addons so I can actually read some values :slightly_smiling_face:

235

Just a warning, not really related to this addon, but i2c in general.

Some of the GPIO-integrations available seems to block the possibility to read from the bus, even if GPIO don’t have any pins configured.

236

hello,
I try to install it on a Raspi 3, but not working. Or is it only for Rasspi 4/5??

237

I never looked at RPI3 as a viable platform for this.

238

I try it right now with a Pi 5 and its working. So Pi 3 is not comnaptible.
