SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world. And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.
You can get more information from the ac6-tools website and download (registration required) various documents highlighting:

JDK13 - minor error due to API change

Posted by nhtshot on 2020-02-25 18:08

I recently freshly installed my laptop and am receiving a startup error from eclipse. The error is as follows:

ENTRY org.eclipse.core.jobs 4 2 2020-02-25 10:57:19.420

MESSAGE An internal error occurred during: “Initializing External-tools”.

A little quick research shows that the WindowsRegOpenKey method no longer has a variant that accepts (int,[B,int). It requires a long for the first argument.

Here is another project that encountered the same issue.

Can you please make the appropriate change to the stlinkserver plugin?

Thanks
