Hey guys,
Attached tarball of my platform/sx530hs fw:100c :
I enabled filewrite, exp_drv_task and movie_rec tasks.
I disabled jogdial and liveview.
I also removed 'fix_writable_media_flag', as well as 'init_required_fw_features'. It was not clear from reading the port thread that those mods were actually required for the cam to run.. In basic tests, I saw no problems with power-On in play mode, using either button; and I had no problems with my (correctly prepared) bootable SD card.
I tested the resulting build on my cam with lua lib test, hooktest, isobase, setmode, and ubtest; results all good. I do not think my mods here broke anything that was working before.
I tested filewrite function using chdkptp; 'remoteshoot '/path/to/dir' -jpg -shots=1'
It worked - jpg is saved to the PC, in the expected place, bypassing SD card. Resulting jpg on the PC is ok. Jpg numbering seems ok. Remoteshoot w/DNG was not tested.
I wasn't sure how to test exp_drv_task, so beware, it may have bugs.
Movie_rec was tested from CHDK scripts using cam/gui/buttons. Two small mp4's were made on the cam's SD card; ffplay identifies and plays them.
I could make 'firzipsubcomplete' and post a build for others to test with, but this is my first submit, and I'm nervous that maybe I forgot something, or some other bonehead maneuver, so.. I thought it best that someone with experience had a look first.. Feedback is appreciated.
Thanks to all you guys who share knowledge and help others figure out how to make these ports work.
