Nuclei Studio 2023.10 Nuclei Settings Open Method Affect Other File Open/Select/Drag

创建的工程中，有一些文件存在单击就直接打开的问题，且不能拖拽，包括Nuclei Settings这个也是单击就直接打开了。

How to print memory usage in Nuclei Studio

In order to print memory usage when compile an application, you can do it like this:

Click Nuclei Settings in selected project, and pass extra -Wl,--print-memory-usage in Extra Link Flags, and save settings, and then build this project, you will be able to see memory usage.

Building target: 050hello.elf
Invoking: GNU RISC-V Cross C++ Linker
... ...
Memory region         Used Size  Region Size  %age Used
             ilm:        8280 B        64 KB     12.63%
             ram:         64 KB        64 KB    100.00%
Finished building target: 050hello.elf

Why the ram usage here is 100% used?

For Nuclei SDK or NMSIS template linker script, the stack is placed at the bottom of ram memory, so the ram usage is 100%.

In the 2024.02.DEV version, when importing an external project, there is an issue with abnormal saving of the download/linker script.

In the 2024.02.DEV version, when importing an external project and attempting to modify the download/linker script values in the Nuclei Setting, there is an issue with abnormal saving. The changes made to the script cannot be correctly saved, and the Nuclei Setting is displayed incompletely. However, this problem does not occur in newly created projects.

Nuclei Studio 2024.02 Known Issues

Display items order error when creating nuclei project

Each time when I try to create a dhrystone example project，"Creating Nuclei RISC-V C/C++ project" window will display a different item order as below pictures show.

[Important] Upgrade Nuclei Studio 2023.10 2023.11.17 second update version

We have fixed some bugs and issues found in Nuclei Studio 2023.10 release(2023.11.06 updated version), and update the plugin and online prebuilt Nuclei Studio 2023.10 version on 2023.11.16, see https://github.com/Nuclei-Software/nuclei-studio/blob/main/7-update_nucleistudio_202310_to_fixed_version.md for more details in Chinese.

Build fail when using pre- and post-steps in Nuclei Studio 2023.10

See

This issue is caused by the busybox used by us internally distribute an make utils, which is not working for us, see eclipse-embed-cdt/eclipse-plugins#597 (comment)

Just replace the toolchain/build-tools folder content with win32-buildtools-1.2.zip which is based on https://github.com/xpack-dev-tools/windows-build-tools-xpack/releases/tag/v4.4.1-2

This issue will be solved

Nuclei Studio didn't report error when create same name project

This exist in Nuclei Studio <= 2023.10(2023.11.18)

Nuclei Studio 2023.10 Qemu Debug Configuration RVV Length not passed in qemu command line

Qemu 调试页面下使能了v扩展，且更新了 RVV length，也不会传递。

How to pass extra risc-v ISA like b/p/k/v in Nuclei Studio or Nuclei SDK.

In RISC-V Compiler option, -march option is used to pass your desired RISC-V ISA, see https://gcc.gnu.org/onlinedocs/gcc/RISC-V-Options.html

For the normal imafdc ISA, you can pass it as usual, such as -march=rv32imafdc or -march=rv64imafdc, but from Nuclei RISC-V GCC 13, if you want to pass extra ISA not in normal imafdc, you may need to specify it using multi-letter ISA string.

e.g.

If you want to use b extension with rv32imafdc, you need to pass -march=rv32imafdc_zba_zbb_zbc_zbs.

In our Nuclei SDK, we defined a Makefile variable used in command line called ARCH_EXT to pass this extra ISA besides CORE defined normal ISA, see https://doc.nucleisys.com/nuclei_sdk/develop/buildsystem.html#arch-ext for details(Please click it and read it carefully).

If you want to set it in Nuclei Studio, when you create project using Nuclei SDK NPK >= 0.5.0, you can set Nuclei ARCH Extensions to _zba_zbb_zbc_zbs, and select Nuclei RISC-V Core to represent the correct base cpu isa.

WARNING don't put ARCH_EXT=_zba_zbb_zbc_zbs like string in IDE, it is only used in Nuclei SDK command line mode, instead of it, you should put _zba_zbb_zbc_zbs like string.

For ISA using Zc*, just select base cpu isa with c in it, and pass _zc* like isa string in Nuclei ARCH Extensions

If you forget to set extra isa string during project creation, you can change it using Nuclei Settings

Or you can change it in Project Properties like below:

Nuclei Studio 2023.10 Nuclei Settings not working correctly

As above image, when Other extensions passed a v in it, the ARCH value is not correct, which should be rv64imafcv but it is set to r64imafc, which cause the -march option not passed during compiling since the ARCH is totally wrong.

Migrate npk.yml for Nuclei Studio 2023.10

If you want to use old npk package built for gcc10 in latest Nuclei Studio 2023.10 with gcc13, if you don't want to upgrade your npk package, you can follow chapter 8 of Nuclei Studio User Guide 2023.10 to use it in Nuclei Studio 2023.10.

If you want to upgrade your npk.yml for 2023.10 using gcc13, you need to follow guide here:

See https://github.com/Nuclei-Software/nuclei-studio/blob/main/5-update_npk_to_support_nucleistudio_202310.md
