CLI через Segger J-Link RTT на ARM Cortex-M (или однопортовая лапароскопия)

В этом тексте я написал про то как наладить Shell по интерфейсу SWD . Посылать в прошивку команды и получать ответ. Чтобы можно было работать примерно как с UART только по SWD. Это когда прошивка в коде асинхронно получает текстовую строку от PC и отправляет текст обратно в сторону PC.

Отладка STM32 программатором J-LINK по SWD

В разработке на микроконтроллерах широко распространены J-link программаторы-отладчики. Также доступно клиентское ПО для них Ozone . У J-link есть 20 пиновый разъём. На нем заложены пины для шины SWD и UART . SWD это - двухпроводной полудуплексный интерфейс для программирования микроконтроллеров. В этой заметке я расскажу как прошить микроконтроллер STM32 по SWD шине при помощи программатора J-link.

Mycket nöje!

Alvaro's Blog: where you learn that not all #USB-C #cables are created equal 🤯. Who knew using the wrong cable could turn "plug-and-play" into "plug-and-pray" 🙄? Maybe the #JLink should come with an extra-long cable and a manual on cable #compatibility 📏📚.

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

@cryptomator jFUSE is based on #jep424 (aka #projectpanama​), which is currently a preview feature of #jdk19, so we will update to Cryptomator to the latest jdk shortly.

In order to keep the PPA release for #Ubuntu users working (JDK 19 is not yet available in our targeted distros), we already created an #OpenJDK PPA that we can rely on for building. This is only a build dependency though and thanks to #jlink is not required for end users.

USB Type-C SWD Adapter

Прочитав статью Программируем и отлаживаем STM32 через USB Type-C порт, не нарушая спецификации USB у меня сразу появилась идея, как сделать более правильно и удобнее (как хочешь втыкай кабель, по привычке и рабочий USB 2.0 порт). Получился вот такой вот адаптер для J-Link (для JTAG 10 pin):

It was possible to have separate user cache in #JDK 8 per the deployment config: https://docs.oracle.com/javase/8/docs/technotes/guides/deploy/properties.html

This is removed in JDK 11.

There is discussion of moving to jlink in https://adoptium.net/blog/2021/10/jlink-to-produce-own-runtime/ and https://www.oracle.com/docs/tech/java/javaclientroadmapupdate2018mar.pdf .

However, I do not see anything about caching in #jlink. Does anyone know if this is possible?

#java #openjdk

We are excited 😍 that the bug fix for
#jlink in the #openjdk that two of our maintainers fixed is now also included in JDK 21.0.1

Background: This was blocking the integration of external dependencies in #JabRef and would have prevented important features.

The root cause: A method in java has a limit of 64 KB.... :duke:

https://www.oracle.com/java/technologies/javase/21-0-1-relnotes.html

#java #java21

@java_discussions Great news. For our project his means that we have to wait until 21.0.1 is released to make sure that our #jlink bugfix is inlcuded in the release

I love me some proper tools.

@javahippie

We did the switch early on, especially with #javafx #jlink and #jpackage. We encountered all the difficulties: split packages, missing module descriptors or automatic module names, and occasionally, it's still driving us nuts

However, two of our developers now fixed a bug in #jlink (Method too large with too many modules) that was blocking us, and one could say that we now have a good understanding of the whole interna as well.

Just got my #VisionFive2 #RISCV debugger setup for #NetBSD kernel debugging ready...

I'm now using #openocd, because I wasn't able to convince the GDBServer of #jlink to debug the right core.

Not sure what I can do at that level, because NetBSD and a VisionFive 2 obviously is a hell lot more complex than my own projects on a ESP32-C3. 😆

Guess I need to improve my knowledge of the RISC-V ISA first... 🤓

But I'm open for ideas how to continue...

Currently working on fixing the Method Too Large Error in the #jdk #jlink

Optimization ideas welcome!

Love the answer to the question of why Java has this 64kb limit...

We use #jlink and #jpackage to distribute @cryptomator. This makes the #JDK only a build time requirement. Users don't need to install #Java separately.

The challenge: During a #PPA build (for our users of #Ubuntu based distros) one may only depend on existing software. No downloads allowed. The latest #OpenJDK version in Ubuntu Focal is 17. But we still want to use #Java19.

The solution is to create an intermediary PPA which is allowed as build dependency: https://launchpad.net/~coffeelibs/+archive/ubuntu/openjdk
