Great, thank you!

So far no issues.

I made a few changes to the bakery to create a minimal build: https://github.com/joernheissler/imageb ... ee/minimal
"minimal" means that some vital features are missing. But in my opinion it's better to install those later through apt.

I'm sure that WolfBoot is a great boot loader. But how would one ensure that only an authentic wolfboot is booted? See e.g. https://blog.nviso.eu/2019/04/01/enabling-verified-boot-on-raspberry-pi-3/ The truth is that on a Raspberry Pi 3, it cannot You can add tamper detection: While the device is po...

Hello! The chip goes to sleep after 10 seconds (or 1.3 seconds if so configured, ChipMode bit 2) after it last woke. So even if you do subsequent requests, it will enter sleep mode eventually. This is intentionally by design for security reasons. There are three situations: * Chip is awake. piSerial...

Hallo! Der beste Weg ist meistens, ein virtualenv aufzusetzen und dort hinein mit pip zu installieren. Nicht als Root. python3 -m venv /path/to/venv source /path/to/venv/bin/activate pip install -U wheel pip setuptools pip install scipy Ggfs. muss pip noch sourcecode compilieren. Dafür bräuchtest du...

Hi, there are couple of options. * Being a Debian based system, you could enable automatic upgrade of apt packages from your own debian repository. If you're happy with a new package version, push the update into the repo and they're installed on next cron job run. * Use a configuration tool like an...

I don't think that secure boot is possible on the RevPi. The ATECC508A chip's documentation is available without NDA: https://www.microchip.com/mymicrochip/filehandler.aspx?ddocname=en590686 I asked Microchip if the data sheet is accessible by intention; it is. They decided to make it public now tha...

There are several ways.
* setup a static lease in your dhcp server.
* setup /etc/network/interfaces. You would need an option like "dns-nameservers 10.20.30.40 10.11.12.13" in your eth0 block.
* setup /etc/dhcpcd.conf instead. Search for "Example static IP configuration".

@volker Questions about the crypto chip are coming up frequently. Should there be an entry in the FAQ? Some technical details/links and a clear disclaimer that this is not supported by Kunbus, that piSerial won't be open sourced (because of NDA) and customers who want to use the chip for for product...

Ich hab noch keinen Connect da.
Hoffentlich gibt es einen Kernel-Treiber.
Dann kannst du "apt install watchdog" benutzen.

Achtung: Es gibt schon auf dem core3 irgendeinen Watchdog. Pass auf, dass du die nicht verwechselst!
