SD-Card failing to mount

[BabyKong04]

Hey everyone,

I am using a Crazyflie 2.1 with the lighthouse deck and the Micro-SD card deck. When I connect the CF to the CF client, then the SD card fails to mount. The CF still works as it should, and can still be controlled using the lighthouse system, but the SD card cannot be detected and so unable to log any data.

I have formatted the SD card as MS-DOS (FAT32) and have added the following config.txt file to the SD card:

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)
acc.x
acc.y
acc.z
gyro.x
gyro.y
gyro.z
baro.asl
baro.temp
baro.pressure
stabilizer.roll
stabilizer.pitch
stabilizer.yaw
stabilizer.thrust
ctrltarget.roll
ctrltarget.pitch
ctrltarget.yaw
range.zrange
on:activeMarkerModeChanged

On the console tab I get the following output:

Is the issue with the SD card itself or with the deck? Any ideas as to why the SD card is not being detected by the CF would be appreciated.

Kind regards,
