thanks philmoz, i will test tomorrow....and if it works, the next 2 month or so.
 
and you don't have to make a version for the s95 since these work good enough as they are now.
with 256 gb cards dual partition you can shoot >100.000 images in one run...my best one yet made over 2.5m images before it mechanically died.

i tried creating a dual partition card via the camera, that works despite the missing modules.
but when i tried to format the small partition to fat32 it stated:
Code: [Select]
This drive is too small for fat32 - there must be at least 64k clusters
however, that does not matter fat16 + exfat works....and the first impression is that it is fast! instant startup as with 1 partition exfat....maybe that wait time can go down to 6 sec again? to verify if it only works on the g1x or similar on other cams, i can use a version for the s110-102b if you like...rest is occupied.

Philmoz, Reyalp, this should be implemented on all cams that boot from fat32, it is a mayor step forward in my opinion.....maybe with a disclaimer 'for crazy large cards that create a missing module error at startup' use dual partition with exfat !
although it might already improve performance at 64gb cards it might not be as noticable. i don't know if this is wishfull thinking on my part, but the g1x seems quicker ready after a shot and more responsive in between now it's working with dual partition fat16/exfat opposed to a smaller size fat32 formatted card.

while my collection of working s95's is dwindling down i thought there would come a time that i would never, ever had to use those frustrating dual partition cards anymore. and now i'm promoting it's return  :D

Test version with dual partition support for S110 1.02b.

CHDK ports:
  sx30is (1.00c, 1.00h, 1.00l, 1.00n & 1.00p)
  g12 (1.00c, 1.00e, 1.00f & 1.00g)
  sx130is (1.01d & 1.01f)
  ixus310hs (1.00a & 1.01a)
  sx40hs (1.00d, 1.00g & 1.00i)
  g1x (1.00e, 1.00f & 1.00g)

tested the s110, works too and again, faster boot with exfat dual partition on a larger sd card than fat32 single partition on a much smaller card.
as for response and speed...it feels better, but have no figures or test to back that up.

if you have 2x 64gb or larger cards i would advise you to try yourself. the difference is amaizing.  :) :D 8) :-* :lol

while the experience seems smoother on the s110, the g1x is almost like a different camera.

Reyalp, if you rather have that wait time set back to 6 seconds, i'm willing to try if that works dual boot on the g1x and s110. seeing the results i think it will.

The two test builds have the startup wait time at 10 seconds not the 20 seconds from reyalp's test build.
It used to be 4 seconds; but I would probably leave this at 10 as it still helps with other cameras like the S95.
CHDK ports:
  sx30is (1.00c, 1.00h, 1.00l, 1.00n & 1.00p)
  g12 (1.00c, 1.00e, 1.00f & 1.00g)
  sx130is (1.01d & 1.01f)
  ixus310hs (1.00a & 1.01a)
  sx40hs (1.00d, 1.00g & 1.00i)
  g1x (1.00e, 1.00f & 1.00g)
  g5x (1.00c, 1.01a, 1.01b)
  g7x2 (1.01a, 1.01b, 1.10b)

Yeah, it's been at 10 seconds for a long time (May 2019, meaning it was included in 1.5 release) without complaints.

If I were confident there were no cameras missing core_spytask_can_start, I'd increase to to 20 or more, since other people are likely using large FAT32 cards as well. I suppose if we set it very long, people with broken ports would complain.
Don't forget what the H stands for.

i was there when it was upped to 10 seconds in may 2019 because of my large sd card for the s95 had missing modules.
and it seemed like a good idea then.
but then exfat on dual partition cards did not work yet as i tested that back then as mentioned in this thread.
now that's solved i thought you might want to reconsider.

even if your port is not broken.
the test with 20 seconds from a few days back is failing on the g1x since it won't start up normally but needs a 5 sec [on] press, so i wouldn't recommend that.

and obviously it is nice to be able to choose between fat32 single or exfat dual partition.
but because of the speed boost i think i will follow industry standard and will format all larger than 32gb cards to exfat from now on....if the cams chdk supports it.

My biggest FAT32 card is 128GB. So far I had no problems with the M3 and G1x. I do have a 256GB card for the G1x but I only use it with exFAT.

philmoz, i was aware that your test build had only a 10 sec delay. since it stated missing modules before i made the card dual boot.

c_joerg, as pointed out hereabove, the 256gb card size was solved in may 2019 by extending wait time to 10 seconds
this is not about those problems anymore, both formats will work. it is about speed.
didn't you see a startup difference with the 128 gb card fat32 vs the 256gb exfat?

with my new card it went from >14 seconds startup to <2 seconds for the canon splash screen...i'm guessing it might be less distinct on a 128gb card, but it's such a difference it should be noticable.

When starting via firmware update I see no difference. I can't start automatically with the exfat, so no compare.
