Canon EOS R5 Mark II freezing with all Angelbird CF-Express Type B cards

[hannestell]

With my Canon R5 Mark II, I got some serious issues with Angelbird CF-Express B cards. Every time I boot-up the R5II in movie mode, the camera freezes instantly after the screen goes on but before the control elements of the screen are shown. It consistently happens with both an AV PRO 256GB and an AV PRO 1TB. It seems as if the camera couldn't access the card or something. Switching off won't work, the battery has to be ejected, the camera has to be put in photo mode before the battery is put back in again. In photo mode though, the camera does boot up and I can switch into movie mode sometimes without freezing. It's a bit annoying since a range of tested SanDisk CF-Ex-B Extreme Pro cards with different capacities all work seemlessly.. 

The use of the Refresh via SSD Manager and FW update tool of the cards didn't change anything.

Please fix it with the upcoming FW update Canon. ASAP. This is making the camera borderline unusable.

The R5II has FW 1.0.2 installed. I checked disabling all other settings like network and power saver and so on..

Spot on Rick.

Have you contacted AngelBird about the cards not working correctly in the camera.

Greetings,

Please save your current configuration to an SD card.  Now reset the cameras, main and custom settings.  Retest with the Angel bird cards.

Sure, the conversation is ongoing. Taken into consideration though that the cards work as expected in camera, I'd logically rule out corrupted cards. Those Angelbird cards both work in the exact same R5II body in both photo and movie mode. Just when booting up they camera freezes. Also booting up in other Canon cameras like my R5 Mark I and the C300 Mark III (of course after initializing media) is working fine. So my logic dictates an error in the card reading process of the R5 Mark II.

Can you follow my logic?

Thanks, this was very helpful. For now indeed the freezing does not occur with the cards anymore. 🙏
