There was a source reorganization between 4.11 and 5 to ease the transition to waf. This command finds the same set of bsp-post-link definitions once you are on the 4.11 branch. find c/src/lib/libbsp -name "*.cfg" | xargs -e grep post- I mentioned there was a few patterns of what these do. mrm332.cfg is creating an S-Record image to download. mvme2100.cfg is creating a compressed binary with a program prepended that decompresses it and jumps to it. I'd suggest using Google Sheets to capture a list of every BSP with a bsp-post-link stanza and a second column to categorize them based on the output format. You and I have talked about the compressed binary with header, S-Records, and mkimage for U-Boot. I would expect that without those types, you will find similarities and a set of repeating things that get tailored from BSP to BSP. Compare two that have the same output format. The S-Record output ones should be easy to compare. > Also I have started making a draft on this project and wanted to know > where I should post it to get some initial reviews on it. > This is pressing as is getting an application and draft filed with Google. --joel > Thanks, Ayushman > > On Mon, Apr 5, 2021 at 9:35 AM Ayushman Mishra <ayushvidush...@gmail.com> > wrote: > > > > Boot-loader is used to initialize the hardware device , but is there > > any way to simulate the boot-loader without hardware?. > > And I suppose the command "rtems-boot-image" performs somewhat similar > > function to one of the objective of this project "This project is > > about capturing the commands and logic needed to convert the RTEMS > > executable format to the BSP boot loader format" ( 3rd point of "The > > boot image tool can:" > > https://docs.rtems.org/branches/master/user/tools/boot-image.html) > > > > Also I think potential mentors of this project are Chris Johns and > > Joel Sherrill , please correct me if I'm wrong. > > > > On Sun, Apr 4, 2021 at 10:27 PM Ayushman Mishra > > <ayushvidush...@gmail.com> wrote: > > > > > > Respected Sir, > > > I went through project description https://devel.rtems.org/ticket/4272 > > > (BSP Executable Conversion) and wanted to take it as GSOC project. > > > I know python programming ,shell scripting and after working a little > > > bit on project #4334 "Replace Mongoose with Civetweb" (in which I am > > > not able to proceed further) I have gained some knowledge about bsp > > > build system in rtems6. > > > I have already build tools and bsp xilinx_zynq_a9_qemu on rtems5 and > > > rtems6 and package libbsd for bsp erc32 and xilinx_zynq_a9_qemu. > > > > > > Also, I have a few doubts regarding project "BSP Executable > Conversion" : > > > 1.
