Re: [GSoC 2020] : BSP Buildset for EPICS (next steps)
Thank you so much Heinz and Gedare for the suggestion of using sed instead of patches. The good news is that I worked with them and EPICS 7 was built successfully for "xilinx_zynq_a9_qemu" using RSB recipe. The changes I made were as follows: ```diff --git a/source-builder/config/epics-7-1.cfg b/source-builder/config/epics-7-1.cfg index 2398cacf..f51c6582 100644 --- a/source-builder/config/epics-7-1.cfg +++ b/source-builder/config/epics-7-1.cfg @@ -31,10 +31,20 @@ URL: https://epics.mpg.de/ source_dir_epics="epics-base-%{epics_version}" %source setup epics -q -n epics-base-%{epics_version} - %patch setup epics -p1 +# +# Changing the RTEMS Version in epics-base/configure/os/CONFIG_SITE.Common.RTEMS +# +sed -i 's/RTEMS_VERSION = .*/RTEMS_VERSION = 5/g' configure/os/CONFIG_SITE.Common.RTEMS + +# +# Changing the RTEMS Base in epics-base/configure/os/CONFIG_SITE.Common.RTEMS +# +sed -i "s/^RTEMS_BASE .*/RTEMS_BASE = \/home\/mritunjay\/development\/rtems\/\$\(RTEMS_VERSION\)\-arm/g" configure/os/CONFIG_SITE.Common.RTEMS cd ${build_top} + + %build build_top=$(pwd) ``` The changes can be observed from here as well: https://github.com/RTEMS/rtems-source-builder/commit/1e7d7d4237a479dce564711b1080a9b3225e9e9a One issue that remains is that even after adding sha512 has for epics-base-7.0.tar.gz, I am getting "no hash found" warning. However, the build is running successfully. Now that it is seen that sed can be used, the next step, in my opinion, is to develop a logic for making these changes use-oriented as even now, I have to specify my directory in the scripts, the only difference is that I am using sed instead of patch. Thank you again, Heinz and Gedare for introducing me to sed and making me revise some regex as well!

Re: [GSoC 2020] : BSP Buildset for EPICS (next steps)
I think you should not make a patch for these two changes but a simple replacement with e.g. sed. like sed -i ’s/^RTEMS_BASE/RTEMS_BASE = \/home\/mritunjay\/development\/rtems/\$\(RTEMS_VERSION\)-arm\/g’ configure/os/CONFIG_SITE.Common.RTEMS oder so ;-) Viele Grüße Heinz Junkes -- Experience directly varies with equipment ruined. > On 12.

Re: [GSoC 2020] : BSP Buildset for EPICS (next steps)
Hello Mritunjay, I have now finished an EPICS variant that works with libbsd so far. DHCP and NFS work. NTP I added a primitive reader. This is sufficient for testing. You can find the development here: https://gitlab.fhi.mpg.de/junkes/epics-base.git It's not perfect yet. The adaptation to the legacy stack and the processing of the environment variables from the flash (u-boot etc.) is still missing. [h1@earth QtC-epics-base (7.0 *+)]$ ./startQemu softIoc Script name: ./startQemu qemu-system-aarch64: warning: nic cadence_gem.1 has no peer WARNING: OS Clock time was read before being set.

A patch is fine for proof-of-concept, but I don't think we want to have x patches for x BSP targets of EPICS. Maybe it is fine, there aren't that many BSP targets right now, but I can see this kind of patch-based configuration getting a little unwieldy. If you proceed with the patch-based approach, you need to figure out how to pick the right patch to apply based on the target/bsp build. So that would be your next step.

I don't think that makeBaseApp.pl will help you. This is intended to build an example IOC. It takes the settings from the above mentioned configuration files. You "only" need to specify the location of the RTEMS installation in configure/os/CONFIG_SITE.Common.RTEMS. RTEMS_VERSION = RTEMS_BASE = Then you have to define the target in configure/CONFIG_SITE: ... # Which target architectures to cross-compile for. # Definitions in configure/os/CONFIG_SITE..Common # may override this setting. CROSS_COMPILER_TARGET_ARCHS= … e.g. “CROSS_COMPILER_TARGET_ARCHS=RTEMS-xilinx_zynq_a9_qemu" And for each target there must be a file in configure/os: e.g. CONFIG_Common.RTEMS-xilinx_zynq_a9_qemu If it is not provided by EPICS, the RSB should install it there (adapted to the target to be used by epics make). > > 2) "The startup directory in EPICS base contains a perl script, > EpicsHostArch.pl, which can be used to define > EPICS_HOST_ARCH.

This is a hen-and-egg problem because RTEMS is only now in the release phase, so my changes have not been implemented yet. 2) I'm just about to figure out in the Epics Makefiles whether the target was built with the legacy-stack or libbsd-stack. It's working already. Now I also have to adjust the rtems_init.c accordingly. Here I have to clean up a little bit.

[GSoC 2020] : BSP Buildset for EPICS (next steps)
First of all apologies for a little delayed email. The classes have resumed just the day after that 72 hours Hackathon and it became a lot hectic. Finally, I am a little better synchronised now and hoping to catch up pace. Before telling about my research work, let me share with you about the past status. Current Status: 1) Successfully built EPICS7 with RTEMS5 by hand for pc-386 2) Worked for RSB recipe. In its due process, I Wrote: i) rsb/rtems/config/epics/epics-7-1.cfg ii)rsb/rtems/config/epics/epics-base.bset iii)rsb/source-builder/config/epics-7-1.cfg 3) Added Patch for RTEMS-pc-386 support which made the above recipe work successfully. 4) Therefore, Successully built EPICS7 with RTEMS5 by using RSB recipe as well for pc-386 as of now. 5) Sent 4 Patches for review of the same. What problems are in the next steps? 1) How to make it work across different architectures? 2) Exisiting EPICS works on the old legacy network stack. 3) I am not using EPICS upstream branch. It is being built by Heinz's epics playground. 4) Doubts in how to start with testing. My Resarch work for the Problem no: 1 I have gone through the EPICS developer guide from here exhaustively in the past couple of day and here are few interesting things that I found which can help: 1) "The main ingredients of the build system are: • A set of configuration files and tools provided in the EPICS base/configure directory • A corresponding set of configuration files in the /configure directory of a non-base directory structure to be built. The makeBaseApp.pl and makeBaseExt.pl scripts create these configuration files. Many of these files just include a file of the same name from the base/configure directory. • Makefiles in each directory of the directory structure to be built • User created configuration files in build created $(INSTALL_LOCATION)/cfg directories. " Remarks: Now since it is also mentioned in the guide that "makeBaseApp.pl creates directories and then copies template files into the newly created directories while expanding macros in the template files. EPICS base provides two sets of template files: simple and example." Can we think of using makeBaseApp.pl to that end? Making the user allow to change the configurations from the terminal? 2) "The startup directory in EPICS base contains a perl script, EpicsHostArch.pl, which can be used to define EPICS_HOST_ARCH. This script can be invoked with a command line parameter defining the alternate compiler (e.g. if invoking EpicsHostArch.pl yields solaris-sparc, then invoking EpicsHostArch.pl gnu will yield solaris-sparc-gnu). The startup directory also contains scripts to help users set the path and other environment variables" Remarks: As EPICS_HOST_ARCH, can we do something similar for CROSS_COMPILER_TARGET_ARCHS? 3) ") The following is a summary of targets that can be specified for gnumake: • • • . • • . • . • .. where: is an architecture such as solaris-sparc, vxWorks-68040, win32-x86, etc. is help, clean, realclean, distclean, inc, install, build, rebuild, buildInstall, realuninstall, or uninstall" Remarks: Now similar to the above stated, can we work for Cross Compiler target Architecture? These were the little doubts that originated from the research work I did. I will like the opinion of mentors that what can be the optimal way now to approach the project after this? What can be some resources for better research work of the above problems?
