USB-SD-Mux now reads SD Card registers

The USB-SD-Mux is designed to make life easier for embedded software engineers by automating the transfer of an SD card between a host PC (deploying a new software image to the SD card) and an embedded Linux device. Since we have introduced this device into our Embedded Linux development workflow back in 2019 we have probably written thousands of SD card images with it. Now the usbsdmux software controlling the device has gained a new feature: It can now read and decode a few SD card information registers. This makes it possible to gain more insight into the capabilities of the used SD card - especially while developing on low-level software and drivers interfacing with the SD card.

labgrid Tutorials

This week, we started our series of YouTube labgrid tutorials. In the next few weeks we will publish more video tutorials showing you labgrid's features and giving you handy tips and tricks.

Showcase: Remote Working

Zur Projektarbeit mit unseren Kunden gehört die Arbeit mit Prototypen-Hardware. Da wir grundsätzlich parallel für mehrere Kunden an vielen verschieden Projekten arbeiten, bedeutet das eine Flut von Prototypen auf den Schreibtischen unserer Entwickler. Spätestens wenn im Team an einem Prototypen gearbeitet werden soll oder längere Zeit nicht aktiv an einem Projekt gearbeitet wird, muss die Hardware regelmäßig umgezogen und am neuen Arbeitsplatz verkabelt werden. Erschwerend kommt hinzu, dass die Entfernung zwischen unseren Entwickler-Schreibtischen durch die aktuelle Homeoffice-Situation, nicht wie gewohnt in Metern, sondern in Kilometern gemessen wird.

USB-SD-Mux: EMC Testing

Today Jonas and I went to our EMC testing lab to continue the measurements needed to certify electromagnetic compatibility for the USB-SD-Mux.

Pengutronix at FrOSCon 2018

This year, a team from Pengutronix attended FrOSCon in St. Augustin for the first time. We took the opportunity to shake hands, talk about our latest developments and meet hackers interested in working with embedded Linux.

USB-SD-Mux: Automated SD-Card Juggler

Once the bootloader on your embedded device is up and running the development of kernel and userland in PTXdist-based BSPs is usually based on booting from network. Thus there is no need for the developer to write the boot media with a new image.
