First foray into OpenOCD has not gone well. 😅 I seem to be able to communicate with the SAMD21, but I can't flash the bootloader. First issue seems to be "no flash bank found for address 0x00040000". Now I just have to figure out what the f✖✖k that means.

Heureca! I finally got around to compile my first true Baremetal program for #arm .
From a previous project, I had enough parts and PCB to quickly assemble a SAMD21G15 based test circuit.

I finally fully understood, how linkers work too and how my bootup sequence first has to load the .data segment from flash into sram and zero out the .bss section.

$19.90 XIAO Debug Mate ESP32-S3-based 3-in-1 multi-tool acts as a DAPLink debugger, serial monitor, and/or power profiler

https://fed.brid.gy/r/https://www.cnx-software.com/2025/11/27/19-90-xiao-debug-mate-esp32-s3-based-3-in-1-multi-tool-acts-as-a-daplink-debugger-serial-monitor-and-or-power-profiler/

We (SCI Semiconductor) are about to hire some folks in the next couple of months (probably starting in January, since we're about to hit Christmas):

We're aiming to hire 1-3 FAEs, who can build out the open-source bits of the #CHERIoT software stack (including drivers / various communication stacks), build demos, and work with customers on use-case bringup.

We also want to hire someone else on the toolchain side. Primarily #LLDB + #OpenOCD, but also working with our #LLVM (and #RustC) folks.

Let me know if you're interested!

EDIT: We are a full-remote company. It's easiest for us to hire people in the UK (and one of our investors would really like us to hire more people in Sheffield), but elsewhere is possible (though might, for tax purposes, require you to be officially a contractor for a while).

We're also going to be hiring people for our hardware verification and RTL teams soon (more on the verification side than design at the moment, I think). I'm not responsible for them, but I can find out more details if anyone is interested. Our first CHERIoT chip is nearly finished, we're starting to work on the second.

EDIT 2: Thanks to all of the people who have expressed interest (in public and private posts). I'll try to get back to you all next week!

EDIT 3: I hope I've replied to everyone now! If I missed you (there were more replies than I expected!) please let me know. I think we'll aim to do another hiring round over the summer next year, so if the current timeline doesn't work out for you, please still let me know and I'll keep you in mind next time!

Dear #electronics Tooters -- looking for a recommendation for reasonably priced (and open source, preferably) USB JTAG probe to use with #OpenOCD to program ATF15xx #CPLD devices.

Playing with #litex #litescope FPGA logic analyzer. That stuff works super well. What the #FOSS #fpga people (#litex #migen #oss-cad #yosys #openocd and all the others hidden in the toolchain) have done is amazing. The board is a colorlight 5a-75b with an ECP5.

Now it's ARM's turn, Specifically the Core M0 SAMD21E18

There isn't quite the same perfect playlist (although plenty of great resources!) for what I wanted so this will be multi part to get to a "good" place. This post is mostly about the tool chain (arm-gcc/OpenOCD/gdb)

Hardware is the the Adafruit PyRuler which is a fancy Trinket M0

ToolChain: Настройка Сборки Прошивок для Микроконтроллеров Artety из MakeFile

Настало время освоить очередное семейство микроконтроллеров: от компании Artery Technology. Компания Artery Technology уже возвела полноценную экосистему для своих процессоров. Есть фирменные отладочные платы, программаторы, документация, исходные коды MCAL и даже кодо генераторы. В этом тексте я представил пошаговую инструкцию того как запрограммировать микроконтроллер Artery.

Hi, I'm a software and hardware engineer with an enthusiasm for #foss and #oshw; *all* of my computers run #linux. I am also a citizen scientist, I operate a #magnetometer for #aurora detection. On GitHub you can find various software libraries that I've written, and also the hardware files for some low-cost magnetometers I designed. I've recently submitted a few contributions to the #openocd debugger project.
