Platformio-core: Add support for Nuclei RISC-V Processor development platform

[fanghuaqi]

Feature Request

Hi, we have developed several RISC-V processors called Nuclei, covering from low-end to high-end use cases.

We have supported three boards:

• HummingBird FPGA evaluation board which will run Nuclei N/NX processor FPGA bitstream file
• Nuclei RV-Star Evaluation Board
• GD32VF103V Evaluation Board which this MCU on board is based on our Nuclei RISC-V Processor Core

Our support for Nuclei Platform currently is using our Nuclei Embedded Software Development Kit, and you can find our support repo here: https://github.com/Nuclei-Software/platform-nuclei.

Currently, our software development tools are kept in github release here: https://github.com/Nuclei-Software/platform-nuclei/releases/tag/nuclei_tools_v0.1.0-alpha.

I think we still missing the following tasks need to be done:

• [x] Add information about nuclei platform and boards to main documentation
• [x] Add information about nuclei platform and boards to PlatformIO Web Site

Questions

And during the support, I also found that debugging in VSCode is slower than debugging in GNU MCU Eclipse with RISC-V support, even we are using the same openocd and riscv-gdb tool, and also open all the windows like registers, call stacks, peripherals, variables, etc, VSCode is much slower than Eclipse, do you have any experiences in these?

I also found that in these line of code:
https://github.com/platformio/platformio-core/blob/develop/platformio/commands/debug/server.py#L73-L75
~py
args.extend(
["-c", "gdb_port pipe; tcl_port disabled; telnet_port disabled"]
)
~
In openocd manual, it suggest to write the openocd file into log file in order to ensure that the pipe is not saturated when using higher debug level outputs, I tried to modify it like this:
~py
args.extend(
["-c", "gdb_port pipe; log_output openocd.log; tcl_port disabled; telnet_port disabled"]
)
~
Then the debug server connection speed and download speed will be faster than before, if you use load command, with previous version, the download speed will be 1 KB/s, but after my modification, it will be 7KB/s.

• Download Speed Before
  

• Download Speed Now
  

• Debug is really slow in VSCode, when all debug windows are clicked and opened

Hi Huaqi,

Are you from Nuclei company?

[fanghuaqi]

Hi Huaqi,

Are you from Nuclei company?

Yes, I am from Nuclei.

[ivankravets]

Thanks! We will back soon with updates for this issue.

[fanghuaqi]

Thanks, BTW, could you take a look at another issue post by me, we are also consider about using platformio offline, but currently I didn't find a good solution for it.

[fanghuaqi]

Hi @valeros @ivankravets , if you need any information from our company or me, please let me know.

[ivankravets]

@valeros please review https://github.com/Nuclei-Software/platform-nuclei

[fanghuaqi]

BTW, here is our company's logo, could you also add it into https://platformio.org/ when you accept this feature?

[valeros]

Hi @fanghuaqi ! I've opened a few issues in your platform repository, do you mind checking them out?

[fanghuaqi]

Hi @fanghuaqi ! I've opened a few issues in your platform repository, do you mind checking them out?

Thanks @valeros , I will check them out, and review it, do you mind I add you into this platform repository, I will send invite to you.

[fanghuaqi]

Hi @valeros , I have done some updates in the our support, could you take a look at it.

[fanghuaqi]

Hi all , any updates or what help do I need to provide? We want to tell our customer that we can use platformio ide, so they can go to your website, and find the documentation there?

[valeros]

Hi @fanghuaqi I see all issues I submitted to your repository are still open, do you plan to resolve them?

[fanghuaqi]

@valeros I have pushed changes to solve them, could you take a look at it, if ok, I will close the issues, thanks.

[valeros]

@fanghuaqi Great! Do you mind if I submit a PR with minor fixes?

[fanghuaqi]

@valeros That will be great, thanks!

[ivankravets]

@fanghuaqi please pull the latest change into the https://github.com/Nuclei-Software/platform-nuclei repository and re-test uploading+debugging. We renamed "nuclei-rv-debugger" to "rv-link" to avoid duplicate items in our documentation.

I can't test it. There is no support for macOS. If everything works, we will make the first public release and add dev-platform to our ecosystem.

[fanghuaqi]

Thank you a lot @ivankravets @valeros, I will test it later, I have submit some issues I found it about documentation, could you take a look at it.

[fanghuaqi]

If possible, could you also add our logo into this page?

[ivankravets]

Done! https://platformio.org/

Thanks for using PlatformIO! Could you add PlatformIO at https://nucleisys.com/product.php (Partners list)?
The horizontal logo is attached.

[fanghuaqi]

Hi @ivankravets , Thank you very much, of course, we are redesign our website, will add your logo when it is ready.

Thanks
Huaqi

[fanghuaqi]

Done with our website, now we also have english version website.

Thanks
Huaqi

[ivankravets]

Thanks!

1. Is it possible to add PlatformIO IDE here https://nucleisys.com/download.php ?
2. Do you plan to add support for macOS (toolchain, openOCD)?

[fanghuaqi]

Hi @ivankravets, I will check with team about these items.

• For item 1, do you mean, add the PlatformIO IDE link to our tools section? Do you have a page for Nuclei, and user can follow it to install PlatformIO IDE?
  Currently I am writing documentation for Nuclei SDK, I plan to add a link to PlatformIO IDE, if user want to work with it.

1. Currently we didn't provide support for macOS, I think of course in future we would like to do it.

Thanks
Huaqi

Hi,

1) Yes, we have these links:

• https://platformio.org/platformio-ide
• https://platformio.org/platforms/nuclei
• https://docs.platformio.org/en/latest/platforms/nuclei.html

Nevertheless, if you work on own docs it is even better. Please share a link with us later.

2) Thanks! I see a lot of requests for macOS.
