[GitHub] [incubator-nuttx-apps] patacongo opened a new issue #246: Illegal calls to romdisk_register()

patacongo opened a new issue #246:
URL: https://github.com/apache/incubator-nuttx-apps/issues/246


   Several examples (and other things under apps/) make illegal calls to `romdisk_register()`.  This both violates the portable POSIX OS interface and makes these applications un-usable in PROTECTED and KERNEL build modes.
   
   Non-compliant examples include:
   
       examples/bastest, examples/elf, examples/module,
       examples/nxflat, examples/posix_spawn, examples/romfs,
       examples/sotest, examples/thttpd, examples/unionfs
   
   These examples are simple demos and, hence, you could argue that it is not so bad that they violate the interface for the purpose of demonstration (although they do set a bad example because of this).
   
   These examples should, of course, use boardctl(BOARDIOC_ROMDISK)  to create the ROM disk instead of calling `romdisk_register() `directly.

   Hi @tanushreebaindur,
   I've tested commit 2217d2f0d34c67e30ac32f089410308a6ca6a061. Now the build fails with the following error:
   ```
   ../nuttx/arch/arm/src/board/libboard.a(lm_appinit.o): In function `board_app_initialize':
   lm_appinit.c:(.text+0x46): undefined reference to `mmcsd_spislotinitialize'
   make[1]: *** [Makefile:156: nuttx] Error 1
   ```
   Steps to reproduce are the same as I previously wrote.

   Thank you. I was able to run nxflat examples using your instructions. 
   
   To run the nxflat examples I used a 32 bit virtual machine (Virtual Box) to generate nuttx.bin and then used qemu-system-arm which I installed on the host computer.
   
   Would you be able to point me to directions to install QEMU so I can configure and build nuttx for different configurations on it? That way I wouldn't need Virtual Box. Thanks again.

   Hi @tanushreebaindur,
   
   I installed QEMU on my laptop (Debian 10) as follows:
   `$ sudo apt-get install qemu-system-arm`
   
   What host OS are you using?

   @tanushreebaindur,
   I tried the recent upstream state and I did not encounter that error.
   I'm not sure about what namely VM you are using. What do you mean?

   I accidentally deleted this comment:
   
   Sorry about that. I see that CONFIG_BOARDCTL_ROMDISK is not enabled /nuttx/boards/arm/tiva/eagle100/configs/nxflat/defconfig
   
   CONFIG_BOARDCTL_ROMDISK can be enabled by doing the following in menuconfig: BOARD SELECTION -> Enable application space creation of ROM disks.
   
   I will submit a PR soon with the updated nuttx/boards/arm/tiva/eagle100/configs/nxflat/defconfig file.

   Hi @a-lunev ,
   
   The error is because CONFIG_MMCSD and CONFIG_MMCSD_SPI are not defined. mmcsd_spislotinitialize() is enabled when CONFIG_MMCSD and CONFIG_MMCSD_SPI are defined
   
   I do not have the board and I'm currently using the simulator to make the configuration change.
   
   Can you please make the following change to the configuration and let me know if it works?
   I can then submit a PR for the corrected eagle100:nxflat defconfig
   
   To enable CONFIG_MMCSD: make menuconfig --> Device Drivers --> MMC/SD Driver Support
   To enable CONFIG_MMCSD_SPI: make menuconfig --> Device Drivers --> SPI Driver Support
   
   This is the resulting defconfig after enabling CONFIG_MMCSD and CONFIG_MMCSD_SPI:

   I am new to Nuttx and wanted to know if I can take up this issue. Can the code changes (that is replacing romdisk_register() with boardctl(BOARDIOC_ROMDISK) in all of the non-compliant examples) be tested using the simulator (nsh:sim) configuration or do you recommend using a board for testing?

   I got the master branch version of nuttx and nuttx apps a few days ago and I am using the nsh:sim configuration. 
   
   Using ‘make menuconfig’ I enabled the Memory Manager(MM) debug features including the error, warning and informational output. I then typed ‘make’ and then ran the simulator. This caused the simulator to exit without going to the nsh prompt due to an assertion failing as described below:
   
   Following is part of the output I see  :
   mm_free: Freeing 0x10bd5aef0
   mm_free: Freeing 0x10bd5af10
   mm_free: Freeing 0x10bcdad90
   mm_free: Freeing 0x10bcdadd0
   mm_free: Freeing 0x10bcdad70
   login: mm_free: Freeing 0x10bcd8ef0
   Assertion failed at file:mm_heap/mm_checkcorruption.c line: 101
   
   Line 101 in mm_checkcorruption.c is:
                assert(node->size >= SIZEOF_MM_FREENODE);
   
   Running the simulator without the mm debug features enabled will not cause the above problem. The simulator works fine and comes to the nsh prompt and I am able to run the hello world app and also the examples/bastest app at the nsh prompt.
   
   I wanted to know if I am missing something as the assertion is failing on enabling the mm debug features and not otherwise.

   Yes, thanks for heping @tanushreebaindur. Ether sim or real board is fine since it's a common feature not depend on the particular hardware.

   Thank you so much. I am able to build and run nuttx.bin on my 64 bit host machine. I checked and found that of the above packages are installed on my system. 
   
   The problem was that I was getting the following build errors when building buildroot:
   
   /usr/bin/ld: libsim.a(maverick.o):/nuttx-code/buildroot/toolchain_build_arm_nofpu/gdb-8.0.1/sim/arm/maverick.c:63: multiple definition of `DSPregs'; libsim.a(wrapper.o):/nuttx-code/buildroot/toolchain_build_arm_nofpu/gdb-8.0.1/sim/arm/wrapper.c:130: first defined here

   To solve this problem, I made  code changes in the gdb-8.0.1/sim/arm described here: https://sourceware.org/legacy-ml/gdb-patches/2019-12/msg00250.html because I did not know how to download the patch. After that everything worked.

    Hi @a-lunev ,
   
   With refernce to  your message:
   > There should be a choice to enable or not enable CONFIG_MMCSD and CONFIG_MMCSD_SPI options. The existing defconfig does not have the options enabled.
   
   Thanks for pointing this out. I did not think about it earlier.
   
   I followed the instructions to reproduce the error. After this last step:
   $ cd nuttx-code/nuttx
   $ make CROSSDEV=nuttx-code/buildroot/build_arm_nofpu/staging_dir/bin/arm-nuttx-eabi- \
          MKNXFLAT=nuttx-code/buildroot/build_arm_nofpu/staging_dir/bin/mknxflat \
          LDNXFLAT=nuttx-code/buildroot/build_arm_nofpu/staging_dir/bin/ldnxflat
   
   I get the following error on doing make:
   
   make[3]: *** No rule to make target 'context'.  Stop.
   make[3]: Leaving directory '/home/tanushree/nuttx-code/apps/examples/nxflat'
   Makefile:61: recipe for target '/home/tanushree/nuttx-code/apps/examples/nxflat_context' failed
   make[2]: *** [/home/tanushree/nuttx-code/apps/examples/nxflat_context] Error 2
   make[2]: Leaving directory '/home/tanushree/nuttx-code/apps'
   Makefile:163: recipe for target 'context' failed
   make[1]: *** [context] Error 2
   make[1]: Leaving directory '/home/tanushree/nuttx-code/apps'
   tools/Makefile.unix:342: recipe for target 'context' failed
   make: *** [context] Error 2
   
   I have not made any change to the code and have got it from upstream. It looks like the rule to make context is missing. Did you encounter this error?

   Hi @a-lunev ,
   
   The error is because CONFIG_MMCSD and CONFIG_MMCSD_SPI are not defined. mmcsd_spislotinitialize() is enabled when CONFIG_MMCSD and CONFIG_MMCSD_SPI are defined
   
   I do not have the board and I'm currently using the simulator to make the configuration change.
   
   Can you please make the following change to the configuration and let me know if it works?
   If it does work, can you then submit a PR for the corrected eagle100:nxflat defconfig
   
   To enable CONFIG_MMCSD: make menuconfig --> Device Drivers --> MMC/SD Driver Support
   To enable CONFIG_MMCSD_SPI: make menuconfig --> Device Drivers --> SPI Driver Support
   
   This is the resulting defconfig after enabling CONFIG_MMCSD and CONFIG_MMCSD_SPI:

   @a-lunev ,
   
   The above error was my mistake. I had intentionally edited the nxflat/Makefile some days back while trying something and then deleted it  so that I could update it from upstream. But fetching and merging from upstream to my test branch did not get me a copy of the Makefile, so there was no Makefile in examples/nxflat. I corrected that problem by  cloning the repositories again. 
   
   After that I got the following error on building Nuttx:
   LD: nuttx
   /home/tanushree/nuttx-code/buildroot/build_arm_nofpu/staging_dir/bin/arm-nuttx-eabi-ld: cannot find -lm
   Makefile:155: recipe for target 'nuttx' failed
   make[1]: *** [nuttx] Error 1
   make[1]: Leaving directory '/home/tanushree/nuttx-code/nuttx/arch/arm/src'
   tools/Makefile.unix:422: recipe for target 'nuttx' failed
   make: *** [nuttx] Error 2
   
   To fix the above error I had to enable CONFIG_LIBM using menuconfig (Library Routines --> Standard Math Library).  I used a 32 bit virtual machine for this build because I am getting multiple definition errors when building buildroot on the 64bit machine. But I did not have to make any other configuration changes due to using a 32 bit virtual machine instead of 64 bit. Adding CONFIG_LIBM was the only change.
   
   I was then able to reproduce this error:
   
   ../nuttx/arch/arm/src/board/libboard.a(lm_appinit.o): In function `board_app_initialize':
   lm_appinit.c:(.text+0x46): undefined reference to `mmcsd_spislotinitialize'
   make[1]: *** [Makefile:156: nuttx] Error 1
   
   To fix this error I isolated the call to mmcsd_spislotinitialize  by conditional compilation as you have suggested above. The code now builds successfully.
   
   These are the last few lines of the build:
   make[1]: 'libbinfmt.a' is up to date.
   make[1]: Leaving directory '/home/tanushree/nuttx-code/nuttx/binfmt'
   make[1]: Entering directory '/home/tanushree/nuttx-code/nuttx/arch/arm/src'
   make[2]: Entering directory '/home/tanushree/nuttx-code/nuttx/boards/arm/tiva/eagle100/src'
   make[2]: 'libboard.a' is up to date.
   make[2]: Leaving directory '/home/tanushree/nuttx-code/nuttx/boards/arm/tiva/eagle100/src'
   LD: nuttx
   make[1]: Leaving directory '/home/tanushree/nuttx-code/nuttx/arch/arm/src'
   CP: nuttx.bin
    
   Do you  know if I can run the hello program under nxflat/tests/hello without a board? If not, I will submit a PR so the chnages can be evaluated.

   Hi @tanushreebaindur,
   
   There should be a choice to enable or not enable CONFIG_MMCSD and CONFIG_MMCSD_SPI options. The existing defconfig does not have the options enabled.
   I have not investigated the issue by myself, however I suppose that error should be fixed by isolating the referencing code (according to the error it references mmcsd_spislotinitialize() from lm_appinit.c) by conditional compilation (#ifdef ... #endif) or some other way.
   
   Concerning a physical board, I also do not have it. I can check only for build errors as I wrote in "Steps to reproduce" instructions.

   Sorry about that. I see that CONFIG_BOARDCTL_ROMDISK is not enabled /nuttx/boards/arm/tiva/eagle100/configs/nxflat/defconfig
   
   CONFIG_BOARDCTL_ROMDISK can be enabled by doing the following in menuconfig: BOARD SELECTION -> Enable application space creation of ROM disks.
   
   I will submit a PR soon with the updated nuttx/boards/arm/tiva/eagle100/configs/nxflat/defconfig file.

   However, my Debian 10 is not freshly installed system. Previously I installed many other packages for other needs.
   
   According to README (https://bitbucket.org/nuttx/buildroot.git) the following packages (for Ubuntu 16.4) should be installed on the host OS:

   I did not use KVM for nuttx building. I built NXFLAT Toolchain using Debian 10 (x86_64). Then I built nuttx using NXFLAT Toolchain (based on gcc-7.4.0). All according to the instructions I provided before. I did not experience errors during the build.

   I did not find how to emulate eagle100 board. To test nxflat examples I'm using QEMU that supports lm3s6965-ek board for emulation. Please, check issue #3737 (https://github.com/apache/incubator-nuttx/issues/3737#issuecomment-842768895) for instructions and PR #3763 (https://github.com/apache/incubator-nuttx/pull/3763) that contains configuration file to test nxflat on lm3s6965-ek board using QEMU.

   Host OS is 64 bit Pop OS. It is based on Ubuntu. 
   
   I used the same command (sudo apt-get install qemu-system-arm)to install QEMU and I was able to successfully run nxflat examples. I was wondering if you were also using QEMU as a virtualizer along with KVM to build nuttx.bin. This is because I am only able to build nxflat on a 32 bit machine (which is the 32 bit Ubuntu virtual machine I've installed on my 64 bit host OS.). When I tried to build nxflat on my 64 bit host OS, I get multiple definition errors.

   To solve this problem, I made  code changes in the gdb-8.0.1/sim/arm described here: https://sourceware.org/legacy-ml/gdb-patches/2019-12/msg00250.html because I did not know how to download the patch. After that everything worked.

   @xiaoxiang781216 examples/nxflat and examples/thttpd still contain the illegal calls to the romdisk_register(). I wasn't able to test those on the simulator or board so they are still unchanged. Please let me know if I need to open a new issue to track those 2 examples.
