Canon R5 v 18.1 firmware update not accessible after download

christruhe — Tue, 25 Apr 2023 18:40:07 GMT

Canon R5 v 18.1 firmware update not accessible after download. I have an iMac M1 Pro with Monterey 12.6.1, The download goes to my desktop with a disk icon. 2 folders show when clicking: EOSR5181.FIR AND UPDATE-PROCEDURE-PDF. When I click the.FIR I get a "no application error message". The other file opens reliably as a PDF.

Please advise.

Did you read the instructions that are in the PDF?

The ,fir file is copied to the root directory of the camera card.

Follow Johns advice, and if you don't understand what the "root directory" is, it will be the card itself, not a directory per se. In my case (see example) it is d: so you can just copy/paste to the open area of the card. This is Windows, but should look basically the same on your mac. Of course, yours will be 1.8.1 🙂

FL, thanks for your clear response. I should add that I’ve done several updates prior without issues. And I did read the pdf.

Yes, I see that on my card. I have a full battery. I neglected to add that when I put the card in the camera (set to P) that the camera does not detect the file. After going to the menu, and firmware - I get a message, Memory card containing firmware is required to update. It doesn’t see the card with the .fir file on it. I’ve tried it with 2 different cards, multiple times. Any thoughts?

I did read the pdf. The camera does not see the card. See details below.

The .FIR file needs to be copied to the SD Card. Remove the CFexpress card from the camera for the update.

OK success! I had not removed the pdf file after loading the complete download on my card. I also used the SD card and not the CF Express, which I also removed from the camera. Thanks all for your various guidance. Much appreciated.

I know people have success with that. But I never have removed my CF or CFe cards. But I do always use the SD card for f/w updates. It's funny though, I was going to suggest that because others have said it worked 🙂

I'm just happy that the OP got the f/w updated! WooHoo!!!
