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.
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.
Project work with our customers includes the handling of hardware prototypes. Since work is generally done in parallel, on many project for many customers, there is a constant flood of hardware prototypes accumulating on the desks of our developers. These accumulations of loose boards can become a problem. This is especially the case when a number of people work on a prototype. Another common annoyance occurs when a project has not been worked on for a period of time, as this might involve moving the hardware from one desk (or storage location) to another and setting it up again. Right now, in a situation where working from home is more common and relevant than ever, this has become even more of an issue. The distances between desks and storage locations of our developers are now measured in kilometers, rather than meters.
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.
