• EOS 4000D / 3000D / Rebel T100 Development I saw no development. I shall attempt!
• EOS 4000D / 3000D / Rebel T100 Development All page Oh yeah, once again, apply this ROM Patch! It’s even listed on that 4000D thread.
• EOS 1300D / Kiss X80 / Rebel T6 Development We were told by a1ex himself to go follow here after that main 3000D thread.
• Initiated Introduction at ML forum

Steps:

• Dump ROM. Not yet! (I have to wait for my younger sister finished her semester (around April-June 2023) first before I can risk my own camera! Maybe DM me for ROM file?? idk.., OR convinve me just ROM dumping FIR never bricks the camera.)
  • Does just running ROM Dumper FIR has potential to brick the camera? If 0% brick chance, then I can just do it now!
  • I have no contact yet for you to give me the ROM at the moment. I shall reserve username, yeee.. Magic Lantern forum username = JOELwindows7
• Prepare QEMU.
  • Seriously updated the Magic Lantern hg repository to qemu with -C argument. in magic-lantern directory, hg update qemu -C!
  • ./install.sh with WSL
  • hangs at Initialized empty Git repository in /mnt/w/kolmo_simple/Artistic_Setups/MagicLantern.fm/qemu-eos/qemu-2.5.0/.git/. how long? is it hang? or is it processing?!?!??!?!
  • nvm, it goes again. Yes, it took long time.
  • Let the script compile QEMU as well.
  • damn! it errors again!
  • kay you know what, like said just bypass those WError with ./configure-eos --disable-werror in the qemu-eos/qemu-2.5.0 directory. keep in mind the qemu-eos repo is outside this magic-lantern directory!
  • try just do
  • still error! here last install.log & config.log. Pls help what’s wrong?!?!?!??!?!??!???!
  • VM trye faile VM hang
  • QEMU reticulatedpines not working. issue
  • Issue closed. but suggested new repo instead. Beware! Over 90K commits, be patient when cloning!
  • Configure success! at first the configure scripts werrors. log! Fortunately found this answer. Yep, that’s because the configure script line endings somehow are in DOS format. And So I installed that dos2unix package, & then dos2unix ../qemu-eos/configure file. Run again it works.
  • Make werror! log! Idk what went wrong. I’ve checked the script folder there, it has all the stuffs including the ones it said it couldn’t find, the the git_submodule.h. Oh yeah uh.. the Makefile, scripts. & python are.. symbolic link? shown in cyan.. yeh..
  • I think I’ve been typo this whole time. log1 & log2 (fixed finally) & log continued
  • I saw the qemu-eos-build/script folder is linked to that qemu-eos/scripts folder. Yes, if you ls -l a symlink, you can see where folder did it linked to. I did ls -l scripts and saw that.
  • Oh God, the same bin/sh^M error again. I believe we’ve got all of those file in DOS / Windows Line endings! lemme figure this out how to resolve all of those files & then each to be converted.
  • Also, Do not forget to add Executable permissions! it error Permission denied to especially sh script without extention!
  • Figured out! in that qemu-eos/scripts folder, you do this for FILER in ./*; do chmod +x $FILER; dos2unix $FILER; done. Basically query everything (for) right here, and for each (for FILER) in here (& possibly recursive to directories idk..), add executable rights (chmod +x $FILER) also convert line endings to Unix ones (dos2unix $FILER). Yes, the FILER variable is the each file.
  • make clean should now works. Hopefully.
  • After this, try again. make -j12. Remember, My laptop (ASUS ROG GL503GE) has 12 thread because on Intel, each core has 2 thread, and this i7-8750H is Hexa core. Six times 2 threads a core equals 12 total threads (6 * 2 = 12). so the -j number is 12. Easy math (disclaimer, I still hate math). How many core you have, times two. that’s your -j number. If you forgot this -j it’s okay, though it will take extremely long, as you only used just that 1 thread. Now I wonder if somebody can -j128 with Threadripper idk lmao!
  • somehow my internet failed, cannot clone some stuffs. log
  • Internet available. try again!
  • failed! log here Somehow character did not seen properly.
  • dos2unix-ify suggestion overruled (or is it? says it’s inappropriate fix). It edits the file & would risk messing further commits (compare & stuffs) to upstream. The Git will track those changed file & treat it as huge change, which will break comparison compatibilities in case other people made changes on other forks, idk.
  • I could not figure out what cause of this CRLF madness atm.
  • who create_config did messed up the config_host.h?!?!? snippet
  • Update in repo qemu-eos available! git stash -a now to stash changes! Then git pull. Return to qemu-eos-build! log. You can see what changed.
  • made sure make clean, make -j12 again.
  • Different fail! log
  • I think I forgot to update that magiclantern_simplified. So yeah, let’s update.
  • have make clean qemu-eos-build, try again. still failed. log
  • pls clean up & redo exactly said. give last source that causes problem the sha1sum. here’s how
  • Same Failed! log & sha1sum of vpc.c in qemu-eos repo is f9ad389e82886eb53f242bde967519fac416e891.
  • Suggested that GCC version too high. my GCC is 11.3.0 (use gcc --version) right now! log
  • Okay, package gcc-10 exist. and ./configure has a way to choose older GCC. here’s how.
  • ah crack. log
  • Somehow GCC still stuck at here 11. Sigh! you know what, let’s break my WSL. we’re gonna make the gcc defaults to 10. Found way! Replace the 4.X.X thingy with 10!!
  • fail
  • Okay, go back to GCC 9? Fail different error.
  • Maybe I forgot to last step in that stack overflow? clear alternatives & update alternatives to 10 again, do not forget configure that update alternatives!. okay nothing happens because I only have installed 1 alternative for each.
  • try again. configure with --disable-werror. same -nopie mistake error. log
  • Ubuntu horribly fails! Gave up! IDK HOW TO GCC!!! Just iso the Debian 11 Bullseye instead! AAAAAAAAAAAAAAAAAAAAAAAAAAAA
  • Virtualbox setup! install essential.
  • idk, sort of working.
  • Python missing vncdotool but fortunately I just have to pip intall vncdotool wtf!??!?!
  • QEMU COMPILE WORKS!!!… right? I need the dumped ROM to test it out. wrong log, here’s recompiled one
  • finally able install Guest Addition. Oh yeah, will share VHD later.
  • & vboxguest working. Damn, I’m sorry I have lost the URL where article tutorial is from.
  • also pls clone OG ML source code in the VHD
  • Moar doing. log1 BISON LEX, log2 try again
  • Hey, Download Ghidra man! https://ghidra-sre.org/ . Source code. You haven’t been downloading ghidra where you should’ve the first time hearing it in LiveOverflow YouTube channel.
  • FORGOR RECONFIGURE WHOOPS. also I too late, there’s already that Debian WSL. Yeah I get upset easily for compile failures after all these years experiencing so many hard to figure why fails. Don’t worry, we’ll get both of them cleaned, configured & compiled.
  • here command you should copy. here
  • Install Debian WSL. Download & Info here
  • Install packages as much as I remember
  • Make directories & almost forgot the vncdotool pip
  • Clone ML Simplified & QEMU simplified
  • Forgot libgtk
  • Compile QEMU works too
  • Test works sort of idk…
  • Also pls fix the VM Debian ML too
  • My mom said about 24th December 2022, she will have the final exam of the semester.
  • Ah damn it, I thought I’ve already installed bison & flex what the peck?!
  • sigh let’s just do it again
  • install bison & flex also on the VM
  • Make again VM WORKS whew!
  • Dump the ROM now! (Pls wait! Waiting for my younger sister to complete her semester with Photography subject. I think about Feb to June 2023. If you can convince me that just running ROM Dumper FIR definitely do not brick my only camera, I can do this now.)
• Reattempt porting ML.
  • Prepared the ML source
  • Test compile anything.
  • FAILED! here last make zip log!
  • names_are_hard replied. Kay, you told me to change things in the Makefile.top, okay, hold on. let me this.. and then that..
  • Right, For QEMU, I gotta learn how to make configurator points to modern QEMU. well let’s just try the ML compiler first. make clean! make zip again.
  • faile! module_string missing! here make zip log again.
  • Oh wow, just as I go back to reticulatedpines’ magic-lantern simplified everything works again. that’s not the qemu. I test compiled the 100D version. here make zip log. it even had the zip file on hand. Yes, clicking that downloads it. I think I should try the others. Note, that one I have no Makefile.user file there, just let it uses the Makefile.user.default entirely.
  • okay, just the 200D ones ironically does not work. here make zip log. Dude, what did make yours work? Think I should make issue over there?
  • EOS M version works too! download zip, see make zip log.
  • Issue closed, reticulatedpines no longer maintain QEMU on that Magic Lantern anymore, instead on the separate repo here.
  • oh wait, reticulatedpines == names_are_hard?!?!? LMAO lol! Oh okay, is that right? anyways..
  • he said that I happened to used that GCC 5, too old for this. Now, idk how am I supposed to prevent the make from choosing that wrong version? Okay, in names_are_hard / reticulatedpines ML, I did Makefile.user, only contains a line of ARM_PATH=/usr.
  • & for good measure, I move away those old gcc original ML repo downloaded. yeah just put those gcc directories into hide folder e.g.
  • my rst2html --version command outputs rst2html (Docutils 0.17.1 [release], Python 3.10.6, on linux).
  • Try again 200D. Well it works. here file. and log too.
  • Now, let’s see if QEMU ready. Awaiting… DONE
  • Recollect all stuffs from various repos! stubs from ccritix & petabyt’s pieces on the 1300D branch!.. yeah..
  • Prepare Simplified in the VM
  • Forgor Python2 VM
  • montage not found VM
  • Sigh Synaptic this now! VM
  • Oh God! Lots of packages I didn’t install! VM
  • lots complicated! VM
  • I’m tired of this! let’s just compile 1 even make docq skipped! VM WORKS
  • Try & attempt combining. Always test in the QEMU!

Stuffs

• ccritix’s 3000D Platform folder Complete with Stubs. Lacks the Installation folder atm. OR try using libUSB method? commit 1
• names_are_hard’s how to QEMU in Magic Lantern Simplified
• eos.c in ccritix Notice the 4000D definition! Ctrl + F and take a look for 4000D Flash ID & stuffs. commit 1
• eos.c in names_are_hard No 4000D definition, but 1300D definition! Ctrl + F that too, it’s in Enumeration. I gotta bring this 4000D in! commit 1
