There is a basic BSP for qemu-virt64-riscv. You can use musl toolchain for riscv64 and follow the traditional way to build RT-Thread Smart:

• musl Toolchain for Windows
• musl Toolchain for Linux

Welcome to explore the world of rt-smart and write your hello smart world program.

[byte-me-stan]

Hello @BernardXiong

Thanks for the information. I couldn't download the musl Toolchain. Could you please double check on your side?

Cheers !

[HimaM-coder]

same here

[Cathy-lulu]

Updated! Check it now.

[BernardXiong]

@Cathy-lulu Could you help me to put the musl toolchains to somewhere?

[HimaM-coder]

Hello,

Sorry to get back late. I am having trouble in setting the toolchain as musl and building the QEMU BSP. I had a look at the articles available it says about the rt-env tool for setting environment variable. (
https://rt-thread.medium.com/get-started-with-rt-thread-smart-opensource-microkernel-operating-system-37e30c9c4ac3 ). But I cannot find the right bat file for environment variable when I checkout from rt-smart branch. Am I missing something? Are we supposed to build this via commandline or using RT-Thread Studio or VS code or something? I assume traditional way means command line. Any guidance is much appreciated.

Thanks,
Hima

[byte-me-stan]

Hello, I am also having the same issue. I can't find the menu to configure the toolchain in rt-env tool and I can't also import the bsp to configure the new toolchain at the project properties . There is no smart-env.bat too.

Hi, You guys can look at this repository now to try running rt-smart. https://github.com/Guozhanxin/rtthread-smart
@HimaM-coder @byte-me-stan @grissiom

[byte-me-stan]

@Guozhanxin
scons under userapps is giving the following error. I played around with the toolchains path in menuconfig but it didn't help. I forgot to mention, I'm on windows 11 (not Linux).

scons

[mariobaldini]

Hello all,
I'd also like to know this: Are we supposed to build this via commandline or using RT-Thread Studio or VS code or something?, raised by @HimaM-coder

The studio is only available for windows, correct? I installed it here using a VM, but it'd be much better to compile directly in my linux host.

Do we have a guide like this (windows) for Linux too?

[BernardXiong]

Hi all,
There is no version of RT-Thread Studio for rt-smart. Please use command line.

If you use Windows, please edit file: smart-env.bat for riscv64 as following:

@set RTT_CC=gcc
@set RTT_EXEC_PATH=%cd%\tools\gnu_gcc\riscv64-linux-musleabi_for_i686-w64-mingw32\bin
@set RTT_CC_PREFIX=riscv64-unknown-linux-musl-
@set PATH=%RTT_EXEC_PATH%;%PATH%

And please run smart-env.bat in your command window. It will setup some environment variables in Windows command line.

[byte-me-stan]

@BernardXiong I have done changing in smart-env.bat file as recommended, however, I am still getting the same error. So, I went into menuconfig to change the Toolchain Path and Prefix of toolchain for rsicv64. And when I invoked the scons command under userapps, I am getting the error as screenshot. I am not sure if I missed out any steps. Could you pls advise me further from here. Thanks !

[BernardXiong]

Is your Host OS Win11?

[byte-me-stan]

@BernardXiong Yes, it is Win11

[HimaM-coder]

Hi @BernardXiong,

The bsp folder build alone works now but I cannot complete it because user apps step is not complete;user apps is not yet working. I am getting error as follows :

D:........\rtthread-smart\userapps

scons
scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...
CC build\hello\main.o
Error in calling command:arm-linux-musleabi-gcc
Exception: No such file or directory

Please check Toolchains PATH setting.

scons: *** [build\hello\main.o] Error 2
scons: building terminated because of errors.

I see that the Linux script for setting environment variable has a line "cp userapps/configs/def_config_riscv64 userapps/.config", are we missing similar ones in Windows by any chance? Seems like some configuration is not setting properly for the userapps folder.

Thanks,
Hima

[BernardXiong]

Wu...

Please use this file to replace userapps/.config file.

If you use Linux as Host OS, this file should be automatically replaced by smart-env.sh script...

[HimaM-coder]

That resolved the intermediate error and now its showing this kind of error:

scons
scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...
CC apps\webclient\packages\webclient-v2.1.2\src\webclient.o
scons: *** [apps\webclient\packages\webclient-v2.1.2\src\webclient.o] Error 1
scons: building terminated because of errors.

Mine is Windows 11. May be this is similar to @byte-me-stan but I did not get pop-up as him.

[BernardXiong]

I don't know either. Maybe @byte-me-stan has a different window environment. I think he can not correctly run riscv64-unknown-linux-musl-gcc because leak of zlib1.dll.

[byte-me-stan]

@BernardXiong Do you think you could help us to setup the remote desktop or vmware on your side with working environment? So that we can remote in and continue with the training until we figure out the solution for all these minor issues?

[HimaM-coder]

something is wrong with path setting for Windows environment. I am unable to resolve the issue.

@HimaM-coder I debugged it further and it didn't work. It didn't compile all the required packages. Sorry for the false alarm :) Does anyone make it work on Linux ?

[mariobaldini]

I'm also trying to setup on Linux.

[matheas95]

im able to compile in wsl2 (windows for subsystem linux) just modify .config from Bernard Xiongs commit. but windows still having problem with zlib1.dll

@matheas95 is it on windows 11 ? it didn't work for me

[matheas95]

please paste what error u encounter

[byte-me-stan]

@matheas95 It is the same old error, am getting. I decided to move on to wsl instead. am now able to compile but interestingly I can't find rtthread.elf file...

[matheas95]

@Cathy-lulu do you know where to get the emulator for windows?

[Cathy-lulu]

Hi @matheas95, here you go: https://qemu.weilnetz.de/w64/2022/

[byte-me-stan]

Hi All,
I got a new issue after scons on wsl. any idea?

[matheas95]

im getting crazy switching wsl and windows.. lets fix windows first. @Cathy-lulu is this correct?

[mariobaldini]

Hi all,
Please let me know if my understanding is correct:

• the compilation itself it Linux based.
• but the studio and documentation are for Windows, because it imports the linux env.

so to run through the docs I'd need:
Linux host -> Create a Windows VM -> follow studio/docs tooling -> internally uses linux libs/subsystem.

Which adds a lot of complexity overall.

For Linux native users: we could download and import the tools directly.

Can we created a dedicated thread for the Linux users to discuss how to run the tools natively?

[matheas95]

once i make wsl work ill document both for windows and wsl

[byte-me-stan]

Hi All,
I can fdisk the sdcard

But I am not able to connect via com port. I made a quick test with stm32 board and I can see the com port at device manager.

Any suggestion?

[HimaM-coder]

The image boot0_sdcard_sun20iw1p1.bin where did you get this? Did this get generated for you? @byte-me-stan

[Rbb666]

The image boot0_sdcard_sun20iw1p1.bin where did you get this? Did this get generated for you? @byte-me-stan

Here it is.

[byte-me-stan]

@HimaM-coder Yes as mentioned by @Rbb666. It is also mentioned in the document posted by @Cathy-lulu

[byte-me-stan]

@Rbb666 Sorry for the late reply. I was fixing some issue with wsl2 and usb disk. Yes, I downloaded from there where you provided but I am getting the above error.. COM port issue, I tried with all the possible COM port number and baud rate. Do I need to install any driver on my laptop windows 11 for COM port ?

[Rbb666]

There is no usb-to-serial port on the development board, you need to connect an external usb-to-serial port module, and then plug it into serial port 0 (pin 7 and 8 of the bottom pin row) through a Dupont cable, the serial port baud rate is 500000, and then plug in the power supply.

[HimaM-coder]

This type of cable is okay right? I don't have one with me. Need to buy.

[byte-me-stan]

@Rbb666 I found one here too but need to order

https://a.co/d/6u297yP

[byte-me-stan]

@Rbb666 I just get the cable but I couldn't fin the pin information about the dev board. Do you know the power 5v and ground pins ?

[Rbb666]

This type of cable is okay right? I don't have one with me. Need to buy.

No problem, you can use this.

[Rbb666]

@Rbb666 I just get the cable but I couldn't fin the pin information about the dev board. Do you know the power 5v and ground pins ?

I uploaded the schematic in the comments below

[Cathy-lulu]

Hi, @stanleylwinn @stanleylwinn how's it going?

[HimaM-coder]

@Rbb666 yes. Same. I'm also stuck. Can you tell us the 5V and 3V3 pins.

[Rbb666]

It is not necessary to connect the power pin, but the common GND is enough

[Rbb666]

It is not necessary to connect the power pin, but the common GND is enough
This is the schematic diagram of the MQ board：

Are your TX and RX inserted reversely?
MQ TX ----> USB TTL RX
MQ RX ----> USB TTL TX

[HimaM-coder]

Yes. I tried both options infact. Thanks, Hima

Hello @Rbb666 ,

Can you give some more assistance with building the lvgl app? I could not build it straight forward by using "scons " command from userapps/media/lvgl directory
It gave an error :

无论有没有 lvgl，这都在那里。当我尝试从普通用户应用程序创建sd.bin时，带有lvgl文件，仍然发生上述错误。您是否有任何关于此错误原因的指针。

Thanks, Hima

"I guess you burned the userapp into the SD card through software, so that the kernel program in your original SD card will be overwritten. You only need to copy the compiled userapp(sdroot.bin) to the USB flash drive that pops up on the SD card.like this:".

[HimaM-coder]

@Rbb666 I did not copy the full userapp folder. I created the sd.bin using the command "sh mksdcard.sh" and then flashing the sd.bin to SDCARD using "sudo dd if=sd.bin of=/dev/sdb bs=1024 seek=56"
Error happened after this.

The SD Card was of 64GB size.

Thanks,
Hima

[Rbb666]

@Rbb666 我没有复制完整的用户应用程序文件夹。我创建了 sd.bin使用命令“sh mksdcard.sh”，然后使用 “sudo dd if=sd.bin of=/dev/sdb bs=1024 seek=56”将 sd.bin 闪烁到 SDCARD“ 在此之后发生错误。

The SD Card was of 64GB size.

Thanks, Hima

You should understand that RT-Smart is divided into kernel and user programs, and the two are separate.To run lvgl, you need to do two things: 1. Follow the previous steps of running RT-Smart to burn the kernel to the sdcard and ensure that it is running properly. 2. Insert the sd card into the computer and copy the compiled lvgl.elf to the sdcard.

Hello @Rbb666

Thank you for the explanation. Booting is working fine now. Do I need to change anything in the lvgl applications? I am getting this kind of an error. I am using the drv_clcd.c files given in the website , as it is without any modification as kernel drivers. Is something missing now?

Also can you guide us on the hardware connection of the LCD board shipped to us. How to connect it to the board?

The userapp for lvgl has been updated, please resynchronize the code：RT-Smart-UserAPP,and make sure the LCD peripheral is enabled in menuconfig.

Is this the right behaviour? I do not have an LCD connected yet. Can you help me in telling me the hardware connection required to connect the LCD module shipped to us, to the MangoPi Board?

Thanks,
Hima

This is the LCD module with me.

Hi @Cathy-lulu @Rbb666

Here goes the final document LVGLGuide_Hima.pdf

Thanks, Hima

Hi,Hima,I have reviewed your tutorial document and it is very detailed.And i have a suggestion: formatting the SD card doesn't have to be done every time, just burn the kernel+UserApp. It is recommended to include formatting the SD card in the final prompt.

[HimaM-coder]

Hello @Rbb666

Understood. I have edited the document and mentioned that these steps needs to be only once.

Hello @Rbb666

Sorry for late update. After formatting and write sb.bin to the disk, I'm getting this error. I'm not sure why. Most likely it could be windows issue. Any idea ?
