problems with A590 101b in build 820

Hi,

I get these errors:
-> main.elf
../platform/a590/sub/101b/libplatformsub.a(boot.o): In function `sub_FFC00FA0_my
':
boot.c:(.text+0x158): undefined reference to `sub_FFE66B1c'
boot.c:(.text+0x1ec): undefined reference to `sub_FFC02D58'
...  This goes on for 1000 lines.

I have no clue.  Can anyone help?  Build 788 worked fine.

Jon

somehow you stubs_auto.S didn't get generated correctly. Revert to the one in svn, check for path issues with your tools.

This belongs in the dev forum btw.

Don't forget what the H stands for.

Sorry for posting in the wrong place!
I recently installed a Norton anti-virus product that is messing with my gmake program.  It hangs, then I kill it.  I must have killed it at the wrong time and it screwed something up.  I reloaded the original build, added my changes and it is now compiling fine.

Following a question from mngc in the sx200 porting thread I am posting this possible fix for testing.

@mngc
the MakeAFScan is a Canon function (but is not called that in the firmware) that is needed by CHDK to make the AF scan during the video.
This function is referenced in the stubs_entry_2.s file for each version, in both a590 versions it is currently pointed at 0xFFC00948 (nullsub_1).
I have had a look and I think I have found the functions in 100e and 101b versions by comparing with the same function in a720.
100e = 0xFFDEEA0C
101b = 0xFFDEEA08

attached is a test build for the 101b for you to try.

If this works the attached patch file can then be added to the trunk by a senior Dev.

I can't test this as I dont have this camera.

Hope this helps
OldGit

EDIT; patch file now moved to the porting thread as advised in following post.

@OldGit

As you pointed the goto link to this thread on sx200 porting page broken, but i analized the link, and found this page.

I downloaded the test build. Wow! The af scan now working properly! This error long time exist, now ok. Many thanks! I try both "set" and "shutter" button, both key working if i selected them. i cannot test the fw. 100e, i have only a590is fw 1.0.1b

Another problem, long time video quality and bitrate mode does not working.  How about in sx200? Correctable in a590is?

I think, the main a590is porting thread (if you want to move the thread):
