General Development / 500D err bmp.o: In function `BMP_VRAM_START':

When I'm trying to build an iso-research firmware for 500D.I met some errors. I have no idea why.

The other day, I took some dual ISO photos using the officially compiled atest Lua updates + fixes 500D firmware.
When I try to export using cr2hdr, I find that the DNG resolution after export is only 384x252

This is my log

General Help Q&A / On the 500D 10 bit RAW video bad frames
« on: June 08, 2020, 02:52:59 PM »
When playing back 10bit raw video on a computer, most of the frames were wrong, as if the frames had been torn apart, sometimes with color bars.
I tried to use FPS override with different frame rate, but the question remains





I don't know why
But I didn't have this problem when I was recording 10bit RAW video in X5 mode.
My camera is 500D
Using the firmware is according to the https://bitbucket.org/hudson/magic-lantern/branch/raw_video_10bit_12bit_LVState compiled firmware https://github.com/wanghurui/hello_world/releases/download/ML/magiclantern-Nightly.2020May25.500D111.zip

Thanks

General Help Q&A / Semi-automatic mode for video?
« on: March 26, 2020, 07:07:19 AM »
Does the magic lantern have a semi-automatic mode for shooting videos, such as fixed shutter speed, auto aperture, and ISO, fixed aperture, auto shutter speed and ISO? Like the Av, Tv mode。
