1)64GB cards are now working for first-time install!!!
(I only had to rename the FIR to 8.3 characters, not less)
Ah, I see why you think it has already answered. I did notice that my exFAT cards were not working with the March 16th nightly before the .FIR 8.3 filename fix, so I did the initial install with a 32GB SDHC card and thereafter made my SDXC cards bootable manually. Since the 8.3 firmware fix, I can take a brand new, unmodified exFAT-formatted SDXC card and put the fixed nightly data onto it, and the .FIR-flashing process makes the card bootable and works great. I am happy to report that I have tested it multiple times on 4 separate SDXC cards at 128GB capacity, all exFAT. ML for 1.2.3 runs great from these cards with the new .FIR file to set it up, and it was also running when I made the cards bootable manually via make_bootable.sh/EOSCard.exe after initial installation on-camera with a 32GB SDHC card.
My problem however is with my Komputerbay 1050x CF card. I cannot get ML to load from this card. If I try to make it bootable on my computer *OR* if I try to make it bootable using the .FIR update method (yes, even with the 8.3 filename fix), it creates a completely unusable card. Whereas it starts as a perfectly mountable/usable exFAT filesystem, after trying to make it bootable via
either method, the camera cannot recgonise it and asks to format it. The laptop fails to mount the partition on the CF card when in the card reader, complaining:
ERROR: invalid VBR checksum 0x258ed093 (expected 0x30c2a1c9).
Furthermore, fdisk reports the filesystem to be type "W95 FAT32 (LBA)" after making it bootable. Before, fdisk correctly read the partition table and detected the filesystem as type exFAT. I have more SDXC cards around that I can always boot ML from, so I do not strictly
need ML bootability from the CF card, but I want to know if there is something wrong with my CF card itself or the ML install process.
2) I bet you have enabled FPS override.
Oops! You are correct. Sorry about that. I changed to 1080p/24fps in the Canon firmware menu and disabled FPS override. Obviously audio recording is working again! I just wanted to do my RAW testing with 25 fps + audio, but I guess that's not possible atm...
