Hello @ivankravets
Please explain me the process of how to add Lofive board containing FE310-G000 RISC V based microcontroller.

[ivankravets]

Do you have this board?

[PriyamvadAcharya]

Yes,I have this board.
I am thinking of testing custom instructions in RISC V ISA

[ivankravets]

Could you try using e310-arty profile?

[env:lofive]
platform = sifive
framework = freedom-e-sdk
board = e310-arty
monitor_speed = 115200

Hello ivans,
I have tried below lines of code in platformio.ini file but I am getting below error shown in below image

Could you try Husing e310-arty profile?

[env:lofive]
platform = sifive
framework = freedom-e-sdk
board = e310-arty
monitor_speed = 115200

Hello ivans,
I have solved problem shown in image by giving below command
Command:-sudo apt install libftdi1-dev

[ivankravets]

Does it work for you?

[PriyamvadAcharya]

Yes ivankravets,
I worked for me but now I am facing new problem shown by below image

apter_speed_issue.png…]()

[PriyamvadAcharya]

The error is related to adapter speed .
So I have changed minimodule.cfg in directory .platformio/packages/tool-openocd-riscv/share/openocd/scripts/interface/ftdi.
I have added a line below line in minimodule.cfg
adapter_khz 10000
After that I have given below command in platformio
pio update

[PriyamvadAcharya]

But after doing these changes the above error shown in image still occurs.

[ivankravets]

What is your debug tool?

[PriyamvadAcharya]

I am using openocd as debug tool

[ivankravets]

Debug probe/adapter? http://docs.platformio.org/en/latest/plus/debugging.html#tools-debug-probes

Please tell me the whole process of how to add a board which is not supported in Platformio.
Like I have Lofive board which is not supported by Platformio ,so how to upload hex files in this board.
For your information Lofive board contains FE310 microcontroller(same in Hifve1 board made by SIfive).
