Hi everyone,
I’ve just received a Flywoo H743 Mini, but I’m having issues with logging and arming the with the stabile ARDUCOPTER RELASE.
The FC doesn’t have an external SD slot, but it does have 512 MB of internal memory.
If I leave the parameter LOG_BACKEND_TYPE = 1, I can’t arm because I get “Prearm logging failed.”
I was able to arm by setting LOG_BACKEND_TYPE = 4, but no logs are being saved.
Do you have any solutions?
What are your other param settings, especially all logging params.
In such case it is always good to send your complete params file
by having LOG_BACKEND_TYPE = 4, i can’t find any logs saved
With LOG_BACKEND_TYPE = 1, copter can’t be armed.
Kind Regards,
Cool, you just gave the same informtion as before. Dont’ send pictures where parts are disabled by popups. Send your complete param file as file.
Have you rebooted the FCU?
Have you try reducing the LOG_FILE_BUFSIZE?
reduced LOG_FILE_BUFSIZE to 16, same old problem.
attached you can find the param file
cop.param (21.2 KB)
Try “formatting” the flash using backend type 1
Hi Andy
'Could you explain the detailed process?
Hi Andy,
I used mavproxy and i had digit this command-format sd card.
Now it is working, and i’m able to download the log if i keep the copter powered up.
As soon i powered it off-this came up:
Great! I tried to find a way to do this from MP but failed - hopefully we can get the option added. We probably need a “format on first boot” option for hwdef.
why as soon i powered the copter off the log will be missed?
is it a bug?
Oh, hmmn - Geprc were reporting this. This should not happen. Oh I know what is going on. Let me do you a build. Please try this (it’s 4.7, if it works on I can do you a version for 4.6)

that is great, now it works!
Thank you so much for your support Andy.
Anyway this FC has a good memory-512mb-
@andyp1per Hi Andy,
let me know when a stable firmware will be released- I’d like to have this one: arducopter_with_bl.hex
Have a good weekend.
