RT-Thread Version

Hardware Type/Architectures

Sipeed Lichee RV board

Develop Toolchain

riscv64-linux-musleabi_for_x86_64-pc-linux-gnu

Describe the bug

I like this project but can't build for Allwinner D1H on Sipeed Lichee RV board

I use compiler https://github.com/RT-Thread/toolchains-ci/releases/download/v1.7/riscv64-linux-musleabi_for_x86_64-pc-linux-gnu_latest.tar.bz2

I was trying:

On Master or v5.1.0:

1. bsp/allwinner/d1/ - not compiled looks outdated

board/board.c:45:5: error: unknown type name 'rt_mmu_info'
   45 |     rt_mmu_info mmu_info;
      |     ^~~~~~~~~~~

2. bsp/allwinner/d1s/ - not compiled

/mnt/hgfs/allwinner_d1/rt-thread/components/dfs/dfs_v2/filesystems/devfs/devfs.c:68:30: error: 'struct rt_device' has no member named 'ops'; did you mean 'fops'?
   68 |             else if (device->ops && file->vnode->ref_count == 1)
      |                              ^~~
      |                              fops

On v5.0.2:

3. bsp/allwinner/d1/ - not compiled looks outdated

board/board.c:45:5: error: unknown type name 'rt_mmu_info'
   45 |     rt_mmu_info mmu_info;
      |     ^~~~~~~~~~~

4. bsp/allwinner/d1s/ - compiled, but no output to UART.

After I forked v5.0.2 and added:

• bsp\allwinner\d1s\tools\boot0_sdcard_sun20iw1p1_d1s.bin change to varian from https://github.com/smaeul/sun20i_d1_spl.git
• bsp\allwinner\d1s\sbi.bin change to varian from https://github.com/riscv-software-src/opensbi
• Change UART pins and boudrate in config

After this changes board started and shown out to UART.
But loading frosen in rt_thread_mdelay function in files

• bsp/allwinner/libraries/drivers/sdmmc/drv_sdmmc.c
• bsp/allwinner/libraries/sunxi-hal/include/hal/sdmmc/osal/RT-Thread/_os_time.h

Chnage it to rt_hw_us_delay and is finnaly looks like works:

This my changes ec2c0f1

Please could you make it compiled properly in master and figure out what happened with SDMMC driver?

Other additional context

[polarvid]

This BSP has been unmaintained since v5.0.0 I believe 😢

Recent works focused more on milk-v(https://github.com/RT-Thread/rt-thread/tree/master/bsp/cvitek) according to the git log.

[ylyamin]

Hi @polarvid, thank you for your response.
I can maintain D1 bsp, can create pull requests.
But since I’m not an expert in RTT, someone needs to review it. My current solution to just replace thread_delay to hw_delay doesn't seem quite right.

[polarvid]

I have a D1s board to help with the kernel compiling issue on master branch and do some testing on it.

While I'm not an expert in sdhci driver, Im afraid there's not much I can do... 🤔Or you could submit your modification as a PR and wait for more experienced contributors to review it.

[ylyamin]

Hi, @polarvid
It would be great if you could fix the compiling of bsp/allwinner/d1s/ on Master, to keep D1 BSP updated in Master. Thank you for interest.
(I think bsp/allwinner/d1/ folder - looks very old and I believe it can be deleted, bsp/allwinner/d1s/ can be one folder for D1s and D1H)

About sdhci yes looks like needs experts, but with my dirty fix it works, I can do PR.
Want to say actually right now I achieved working LCD RGB and MIPI DCI Display with D1H and RTT, but completely stuck on how to up USB Host function. Host driver initiated but the thread is suspended and nothing happens.

[polarvid]

Thank you for updating me on your progress. I'm truly impressed by the amount of work you've accomplished👍

I think bsp/allwinner/d1/ folder - looks very old and I believe it can be deleted, bsp/allwinner/d1s/ can be one folder for D1s and D1H

Agree

Host driver initiated but the thread is suspended and nothing happens.

you could try the backtrace() to find out where thread suspended or dump more status on it for debugging

Besides,
please feel free to share any details or updates whenever you can. And I do believe that will be valuable to any others who are interested in it.

[ylyamin]

Thank you for the nice words @polarvid .

you could try the backtrace() to find out where thread suspended or dump more status on it for debugging

Yes, I tried backtrace() still can't understand what happened. Thinking maybe instead RTT driver try TinyUSB. Believe I need to create a separate git issue for this topic.

please feel free to share any details or updates whenever you can

I believe now all that was done required a big blog article, maybe I do it someday. Don't know how many people are interested in D1 drivers. Right now I have rough notes: https://github.com/ylyamin/RT-Thread-on-Allwinner-D1H/blob/master/documentation/Code_changes.md

[polarvid]

Hi 😄@ylyamin

I tested the bringup and filesystem in sd on my D1s board, with the branch forked from the latest kernel (on #9142). And to summarize, besides the compiling failure, the sd driver works just fine with me.

Hi, @polarvid

Amazing work, thank you very much for your efforts ! I hope PR will be approved. I am happy that D1 bsp became alive in RTT.
Could you tell me how you handled the compilation failure, it is known how to fix it?

[polarvid]

@ylyamin

And I read your notes on https://github.com/ylyamin/RT-Thread-on-Allwinner-D1H/blob/master/documentation/Code_changes.md, which is incredibly insightful to me. They can be edited and posted to the forum to benefit others in the community if you would love to 😃

[ylyamin]

Hi @polarvid,

Great, so your solve D1S compilation is very good, thanks !
About D1H support, maybe need to suggest RTT masters to use the common D1s-D1H folder. I can create PR to delete old folders and add bootloaders, uart etc. Or you can do PR, I'm a newbie in this. After this, this original issue will be completely solved.

By the way, in your PR proposal to delete rt_hw_us_delay(), I used this function to solve LCD driver frize in my platform, need to think about it.

About Code_changes.md. Yes I want to add more human explanations and pictures and can be published in forum, hope to work with it after fighting with USB.

[polarvid]

delete rt_hw_us_delay()

It seems that API has been implemented on libcpu/risc-v/t-head/c906, so that won't be a problem for your modifications. But with my test on master, the sd seems fine. I am not sure if that will also work with you on d1h board. You could try it on later on master if possible.

the common D1s-D1H folder

I think it could be better if you open a PR on it. Since the proporsal came from you. And I'm willing to help if there is any problem.

[ylyamin]

Understand and agree, thank you for your support!

[ylyamin]

Hi, @polarvid,

If you remember our conversation about RTT and D1H. Sorry I comment in closed issue.

"And I read your notes which is incredibly insightful to me. They can be edited and posted to the forum to benefit others in the community if you would love to 😃"

I create series of articles covering the knowledge and experience I’ve gained: https://github.com/ylyamin/RT-Thread-on-Allwinner-D1H/blob/master/documentation/D1_0_index.md

And share this in forum: https://club.rt-thread.org/ask/article/b66f7db40179a81b.html, https://club.rt-thread.io/ask/article/18.html

However with my D1H project - I still stuck with the USB driver. It can detect device connections, but communication has not started.

[polarvid]

Hi, @ylyamin!

I have read your articles for the D1H board. They are pretty comprehensive!

And if you'd like to, you could provide your email address, so we can easily exchange information more (BTW, you could reach out to me at smokewood@qq.com).
