uSD card deck failing to mount the SD card

[BabyKong04]

Good morning,

I have a crazyflie 2.1 and am using the microSD card deck to log flight data. When I insert the microSD card and connect the crazyflie to the cfclient, then the console shows that it failed to mount the SD card. I've attached my console output below:

The uSD card is formatted as MS-DOS (FAT 32), and I've loaded the following config.txt file onto it:

1 # version
512 # buffer size in bytes
log # file name
1 # enable on startup (0/1)
on:fixedFrequency
250 # frequency
1 # mode (0: disabled, 1: synchronous stabilizer, 2: asynchronous)

stabilizer.yaw
stabilizer.thrust
ctrltarget.roll

Do you have any ideas as to why the sd card is not being read by the sd card deck?

Thanks in advance.

Can you try a default (or any other) config from the examples? Perhaps the one you use exceeds the number of logging parameters, or you have some other mistake in the config. I found that the error messages are not very helpful there.

[BabyKong04]

The config file I'm using is from the crazyflie-firmware repository (tools/usdlog/config.txt).

I tried using only the acc.x, acc.y, and acc.z parameters and still got the same issue. I also tried removing the comments and that made no difference.

Are there better error messages I can find somewhere?

[gemenerik]

Can you try without the Lighthouse deck and see if it makes a difference?
Do you have another sd card you can try?
Can you try formatting it in another way?

[BabyKong04]

I tried without the lighthouse deck as you suggested and it didn't make a difference.

I've tried with a couple of sd cards, but they are the same brand and type of sd card... I've also tried with exFAT format as well. Even when I connect the crazyflie without inserting the sd card (only the sd card deck is attached to the CF) then I get the same error messages. I'm not sure if that means that the deck is working fine and the error message I'm getting is just saying that the deck isn't picking up on any sd card being inserted? Or if that indicates that the issue is with the deck itself?

Thank you for your help!

Interesting. Are you using the latest release firmware? Have you tried adjusting the config.txt settings? It might simply be an SD card compatibility issue—Raspberry Pi, for example, has had so many problems with SD card quality that they even started selling their own. If you can try another quality brand that could help. If it doesn't help, maybe your deck is broken.

Yea I'm on the latest firmware. When I connect the crazyflie to the cfclient, then the parameters indicate that the deck is connected to the crazyflie which makes me think that the issue isn't with the deck itself...?

I'm not sure what you mean by adjusting the config.txt settings... do you mean adjusting the encoding options?

I'll see if I can get another brand of sd card and see if that helps.

Thanks again for your help!
