[GitHub] [incubator-nuttx] TA1DB opened a new issue #1844: BEST SUPPORTED BOARD + NUTTX VERSION
TA1DB opened a new issue #1844:
URL: https://github.com/apache/incubator-nuttx/issues/1844
Hi,
I'm new to Nuttx. I want to make experiments with a board having (or possible to add easily) a display, keypad and network connection; by this way I want to learn nuttx, develop applications on it.
I may also contribute to Nuttx itself in time, but I need to learn it well first.
I don't want to deal with Nuttx's issues right now because I don't have enough experience to resolve these issues anyway and I don't have enough time either!
First I started with stm32f746g-discovery board, I encountered some problems, I wrote them in [this issue]( https://github.com/apache/incubator-nuttx/issues/1643)
Afterwards considering it is more supported I got a stm32f429i-disco (disc1) board, again I encountered a some other problems, but when I used Nuttx version 9.0.0 the problems decreased, still I can't say the situation is satisfactory.
Could someone tell me "I use this card together with this Nuttx version, I recommend these"?
Since I couldn't find any other active forum to ask this question, I had to make my request here, I apologize if I was wrong.
Thank you.

There is also a paragraph in apps/' README file that explains how to add an external application.
(Sorry I'm on my phone and internet is so bad, I'd have given the url directly otherwise)

Thank you very much to everyone who is trying to help me by answering my question here.
On this occasion I would also like to thank to @acassis for kindly answering my questions in LinkedIn messaging.
@anchao I just applied exactly same process [here in @acassis 's blog Using NuttX as library once again ]( https://acassis.wordpress.com/2020/06/28/using-nuttx-as-library-once-again/ )
Everything went as expected until I enter this command:
`$ arm-none-eabi-ld --entry=__start -nostartfiles -nodefaultlibs -T./scripts/ld.script -L./libs hello.o -o nuttx.elf --start-group -lc -larch -lbinfmt -lboard -lboards -ldrivers -lfs -lmm -lsched -lxx "/usr/lib/gcc/arm-none-eabi/9.2.1/thumb/v7e-m/nofp/libgcc.a" --end-group`
then I got the following:

@TA1DB We are doing some serious work trying to improve the state of the documentation around getting started. So I would love to help get you going and maybe we can build that out a bit better.
This is actually why I am trying to build out complete support for this "featherwing" right now https://www.tindie.com/products/arturo182/keyboard-featherwing-qwerty-keyboard-26-lcd/ which could then provide a lot of support for playing with NuttX on some of the lower cost platforms with touch screen keyboard etc...
The **stm32f746g-discovery** looks like an interesting board with the integrated LCD and network support. I just checked about ordering on, but it looks like everyone is out of stock until late November so I am not sure how much help I would be able to provide.
The **stm32f429i-disco** is a rather old board and should be fairly well supported although some board support code may have aged. I do have one of the original ones and would be happy to help get you started with it and could verify that some of the existing configuration are working correctly. What configuration specifically did you try with it? I would start with `stm32f429i-disc:nsh` and then since you were interested in the display `stm32f429i-disc:lvgl`. There are some notes on that here:
**boards/arm/stm32/stm32f429i-disco/README.txt**:
```
lgvl:
----
STM32F429I-DISCO LittlevGL demo example.
The ltdc is initialized during boot up. Interaction with NSH is via
the serial console at 115200 8N1 baud. From the nsh command line
execute the lvgldemo example:
nsh> lvgldemo
The test will execute the calibration process and then run the
LittlevGL demo project.
```
I think going forward we were thinking about doing some focused tutorials on the STM32 Nucleo-144 platform which I personally have the H745 and F767 variants. Note that these do not have displays but do have Ethernet. Connecting and SPI based ILI9341 TFT display via SPI is fairly well supported and I just verified it with the featherwing I mentioned.
Happy to help you get going on this and try to improve the documentation at the same time.

Hi @anchao
Yes there are libs/ directories: ~nuttxspace/nuttx/libs/ and ~hello/nuttx-export-9.0.0/libs ,
however ~nuttxspace/nuttx/libs/ has only libc.a in libc folder, and ~hello/nuttx-export-9.0.0/libs/ has libapps.a and libnuttx.a
Regarding unfound files; Apart from the libboard.a file, all of these "unfound files" are only in the nuttxspace/nuttx/staging/ folder. There is also a libapps.a file in the nuttxspace/nuttx/staging/ folder. On the other hand libboard.a is only in the nuttxspace/nuttx/boards/arm/stm32/stm32f429i-disco/src/ folder.
Note: when I extracted the compressed "export file" it's name was nuttx-export-0.0.0, I changed the name to nuttx-export-9.0.0 for compatibility.

@Ouss4 , Thanks for reminding!
Hi @TA1DB ,
Welcome!
I tried "make export" compiling locally on "Ubuntu 16.04", it seems there is no problem and everything is working as expected, I suspect there may be something wrong with system compatibility, could you please share the detailed compilation process?

Hi @TAIDB ,
The latest version simplifies the link phase and will not require such a complex command line in the future,
Could you please replace :
`$ arm-none-eabi-ld --entry=__start -nostartfiles -nodefaultlibs -T./scripts/ld.script -L./libs hello.o -o nuttx.elf --start-group -lc -larch -lbinfmt -lboard -lboards -ldrivers -lfs -lmm -lsched -lxx "/usr/lib/gcc/arm-none-eabi/9.2.1/thumb/v7e-m/nofp/libgcc.a" --end-group`
instead of :
`$ make import`

Yes but many of them have been modified and I did a lot of work fixing syntax issues during the conversion. I know I can export the space, let me see what I can do on that front. Let's pick it up in the roadmap issue.

@TA1DB @v01d is speaking about option 3 [here](https://cwiki.apache.org/confluence/display/NUTTX/Building+NuttX+with+Applications+Outside+of+the+Source+Tree)
@v01d @adamfeuer This doc is probably very important to move from the wiki and into the documentation and we should document the export function.

> @btashton I've been meaning to ask: are the wiki pages accessible in original format? Are they markdown? It would be much easier to port them to sphinx if so
Yes I have them but it was in docwiki format and many of them have been modified and I did a lot of work fixing syntax issues during the conversion. I know I can export the space, let me see what I can do on that front. Let's pick it up in the roadmap issue.

Btw if @xiaoxiang781216 or @anchao see this they can provide some insights on the state of export. They've been submitting some PRs regarding that.

@btashton
Thank you very much for your kind and helpful response.
I am aware that you are working hard to develop the documentation; this is very good. I also follow your work on the "featherwing" (https://www.linkedin.com/feed/update/urn:li:activity:6712105195817447424).
I would appreciate if you resolve the issues about the stm32f746g-discovery board because it is a very advanced board; In addition to LCD capacitive touch screen and network connection there are many other hardware interfaces (sdcard, microphones, audio output, camera interface, etc.) in addition to microprocessor's own advanced capabilities. I think this board is a very good platform for Nuttx developments and therefore should be well supported.
I had no startup problems with stm32f429i-disco. All configurations including lvgldemo compiled, loaded and worked without any problems. However, when I tried to write my own application using Nuttx as a library with "make export" in version 9.1.0, I encountered errors during compiling. When I went back to version 9.0.0, this time I could pass the compilation phase but got the following errors in the link phase _(tried on both Ubuntu 16.04 and macOS High Sierra installations, same results!)_ :
`apple-MacBook-Pro:nuttx-export-0.0.0 murat$ arm-none-eabi-gcc -c -fno-builtin -Wall -Wstrict-prototypes -Wshadow -Wundef -g -mcpu=cortex-m4 -mthumb -mfloat-abi=soft -I. -isystem ./include -pipe -I "./include" -I "./arch/chip" hello.c -o hello.o

arm-none-eabi-ld: cannot find /usr/lib/gcc/arm-none-eabi/9.2.1/thumb/v7e-m/nofp/libgcc.a: No such file or directory`
I have to overcome this problem because what I really want to do is to be able to write my own applications.
On the other hand I got my answer to my question and therefore I am closing the issue. Thanks again.

Hi @TA1DB
I tried the tutorial in the Mr. Acassis 's blog, linker command works as expected,
```
chao@archer:~/nuttx-export-9.1.0$ arm-none-eabi-ld --entry=__start -nostartfiles -nodefaultlibs -T./scripts/flash.ld -L./libs test.o -o nuttx.elf --start-group -lc -larch -lbinfmt -lboard -lboards -ldrivers -lfs -lmm -lsched -lxx -lgcc --end-group
chao@archer:~/nuttx-export-9.1.0$ ls
arch include libs nuttx.elf registry scripts startup System.map test test.c test.o tools
```
The error you provided seems to be that the ld path does not take effect, It is better to confirm whether the libs/ directory exist or these libraries are actually in the libs/ directory.

I'm glad that worked for you, I'll keep and eye on that other board for when it comes back in stock. Let's figured out what is up with `make export` I personally don't use it, instead I leverage the external apps functionally.
@v01d do you have thoughts on the export issue?

Hi @TAIDB ,
The latest version simplifies the link phase and will not require such a complex command line in the future,
Could you please replace :
`$ make import`
instead of :
`$ arm-none-eabi-ld --entry=__start -nostartfiles -nodefaultlibs -T./scripts/ld.script -L./libs hello.o -o nuttx.elf --start-group -lc -larch -lbinfmt -lboard -lboards -ldrivers -lfs -lmm -lsched -lxx "/usr/lib/gcc/arm-none-eabi/9.2.1/thumb/v7e-m/nofp/libgcc.a" --end-group`

Same here, I use the external apps. @TA1DB maybe you can try this approach? It is simpler. You just add your application in apps/external (it can be a symlink to your app somewhere else).

Thank you very much to everyone who is trying to help me by answering my question here.
On this occasion I would also like to thank to @acassis for his kindly answering my questions in LinkedIn messaging.
@anchao I just applied exactly same process [here in @acassis 's blog "Using NuttX as library once again" ]( https://acassis.wordpress.com/2020/06/28/using-nuttx-as-library-once-again/ )
Everything went as expected until I enter this command:
`$ arm-none-eabi-ld --entry=__start -nostartfiles -nodefaultlibs -T./scripts/ld.script -L./libs hello.o -o nuttx.elf --start-group -lc -larch -lbinfmt -lboard -lboards -ldrivers -lfs -lmm -lsched -lxx "/usr/lib/gcc/arm-none-eabi/9.2.1/thumb/v7e-m/nofp/libgcc.a" --end-group`
then I got the following:
`.apple-MacBook-Pro:hello murat$ cd nuttx-export-9.0.0
apple-MacBook-Pro:nuttx-export-9.0.0 murat$ arm-none-eabi-gcc -c -fno-builtin -Wall -Wstrict-prototypes -Wshadow -Wundef -g -mcpu=cortex-m4 -mthumb -mfloat-abi=soft -I. -isystem ./include -pipe -I "./include" -I "./arch/chip" hello.c -o hello.o

`
Note: with Nuttx version 9.1.0 the first command line (arm-none-eabi-gcc -c ... ) didn't work either.

Hi @anchao
Yes there are libs/ directories: ~nuttxspace/nuttx/libs/ and ~hello/nuttx-export-9.0.0/libs , however ~nuttxspace/nuttx/libs/ has only libc.a in libc folder, and ~hello/nuttx-export-9.0.0/libs/ has libapps.a and libnuttx.a
Regarding unfound files; Apart from the libboard.a file, all of these "unfound files" are only in the nuttxspace/nuttx/staging/ folder. There is also a libapps.a file in the nuttxspace/nuttx/staging/ folder. On the other hand, libboard.a is only in the folder nuttxspace/nuttx/boards/arm/stm32/stm32f429i-disco/src/.
