Adding a Delay to the ARM DAPLink Bootloader

The ARM mbed USB MSD bootloader which is used on many silicon vendor boards has a big problem: it is vulnerable to operating systems like Windows 10 which can brick your board (see “Bricking and Recovering OpenSDA Boards in Windows 8 and 10“). To recover the board, typically a JTAG/SWD programmer has to be used. I have described in articles (see links section) how to recover from that situation, including using an inofficial new bootloader which (mostly) solves the problem. The good news is that ARM (mbed) has released an official and fixed bootloader. The bad news is that this bootloader does not work on every board because of a timing issue: the bootloader mostly enters bootloader mode instated executing the application.

SQUIX ESP8266 based E-Paper WiFi Weather Station

I’m a fan of all kind of weather stations. When Daniel Eichhorn twittered about his new version using an E-Paper display module, I immediately preordered one. I decided to build a station with a custom enclosure, so here is my version of a 3D printed version, featuring magnets so it can be attached to the fridge:

Hiking King Laurin and his Rose Garden

The Dolomites are full of legend and fairy tales (see “The Legend and the Fairy Tale of Lago di Carezza“), and one is about King Laurin and his Rose Garden. In this day hike we visited Haniger Schwaige hut, located below the Torri del Vajolet (Vajoletttürme, 2813 m) and Croda di Re Laurino (König-Laurin-Wand, 2813 m).

Dealing with Eclipse and Very Small Icons on Ultra High Density Displays

More and more these very-very-high-resolution (UHD, Ultra-High-Density) notebook displays show up in my class rooms.These displays have 3100×1800 or even more pixels, making it great for watching high-resolution videos or for playing games (maybe?). But such a high-resolution makes many tools including Eclipse very hard to use, because the toolbar icons get so tiny that they are really hard to hit with a mouse cursor on Windows:

Using Serial Terminal and COM Support in Eclipse Oxygen and Neon

Most of the time I’m using a dedicated terminal program like Termite or PuTTY to connect to a board using virtual or non-virtual COM port. Another way is to use the Eclipse built-in Terminal view: that way no extra program is needed to communicate with a real or virtual COM port to my target device:

How to fix an Eclipse Workspace that does not open any more?

It can happen to everyone using Eclipse: launching Eclipse with workspace, and then it is stuck loading it. As a last resort, create a new workspace and go on? Possible, but painful, right? For some time I have a strange issue nagging me: from time to time, I’m not able to switch to a workspace which worked before. The IDE starts loading, but then is stuck:
