How to log files on SDCard Deck?

[Rwik2000]

I tried the following link from the documentation:
https://www.bitcraze.io/products/micro-sd-card-deck/

I am unable to toggle usd.logging variable between 1/0. How do we change the variable's value while the crazyflie is on?

Here is my config.txt file:

25 # 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)

acc.x
acc.y
acc.z
gyro.x
gyro.y
gyro.z
baro.asl
baro.temp
baro.pressure 

Even though, I enable the startup variable, but it seems it is not able to log.

The config.txt parser is very simple so there might be something in there it can not handle.

Have you tried to remove the extra enter between #mode and the first variable

I will try to remove the white space.
How do I toggle the usd.logging variable? Do I need to turn it to 0, in order to save the log files? If so, how do I do that?

Ah sorry I misunderstood your question as a bug report, so I've converted your issue to a discussion.

You toggle the usb.logging variable through the parameter framework, which you can do from the cfclient. You can open up a parameter tab:

I am still having problems with logging. Whenever, I put the SD card in crazyflie, the CF starts for a few seconds and then I see the front 2 leds flashing red and then the crazyflie restarts. I am not able to log on to the SD Card.

It looks like the start of your config is wrong, the version is missing for instance. You can check out the example file to see what it should look like.
I'm not sure but I think the order of fields is important and also that all of them are added.

Can you tell me a brief step by step procedure of what all to do.
