SX510 1.01A CHDK 1.3.0 not saving RAWs

Not sure if this is the right forum to post (as it is for the stable version only), but I couldn't find any other forum. Anyway, my camera won't always save the RAW files. The saving seems to be very erratic, sometimes it will save it, sometimes not, even in the same shooting session. I tried various raw options, dng or not dng, buffered or not, etc. Nothing seems to affect it.

Does this happen for other cameras as well? Is there something I am doing wrong? All the exceptions are cleared, btw.

A guess: it's possible that some raw files are overwritten due to problems with the file counter (new cameras suffer from that). Do you always get the relatively long delay when shooting raw?

Another idea: make a few test shots with raw enabled:
1) press the shutter button fast (don't wait for focus confirmation etc.)
2) shoot slowly (press shutter halfway, wait until AF and measurements finish, shoot)
and see how many raw files you get for option 1) and 2).

Yep, that was it, I was pushing too fast. If I do a long push, it works fine. Although I think I did have the focus confirmation before, only that it wasn't a long enough push.

Is this a feature or some limitation? I don't remember it being an issue in the past.

It's a bug.

It's an issue with the port - the "fast press" code path is missing the CHDK raw hook. Hopefully nafraf will notice this and fix it soon.

Code: [Select]
"    BL      sub_FF371D20_my \n"  // --> Patched. Old value = 0xFF371D20.
+"BL      capt_seq_hook_raw_here\n" // possible location 1
"    TST     R0, #1 \n"
"    LDMEQFD SP!, {R4-R6,PC} \n"

"loc_FF1D9BF0:\n"
"    STR     R5, [R6] \n"
+"BL      capt_seq_hook_raw_here\n" // possible location 2
"    LDMFD   SP!, {R4-R6,PC} \n"
