  • Can this board be used for reading PWM inputs? Or is the PCA9685 output only?

  • I get 'mmc1: error -84 whilst initialising SD card' but can still manually mount it. Did you try manually mounting the card as per my commands below?

    What is your output from:

    dmesg -T | grep mmc1
  • I have had some success. 'dmesg -T | grep mmc1' showed that it was detecting the SD card at least on mmcblk1. The following commands allowed me to mount the the Kingston SD card on /mnt/mmc. This was strange as it wouldn't work if I specified the partition i.e /dev/mmcblk1p1 as suggested.

    mkdir /mnt/mmc
    mount -t vfat /dev/mmcblk1 /mnt/mmc

    For some reason the Sandisk worked with the partition defined:

    mount -t vfat /dev/mmcblk1p1 /mnt/mmc

    Thanks to the following thread for the tips:

  • I am trying to do exactly the same thing, but I am using Ubilinux. I have tried a Sandisk 16GB Ultra SDHC, and a Kingston 4GB SDHC. Both do not mount automatically and 'df -h' does not show any drives. Any suggestions SF?

  • Did you find out the answer to this? I'm trying to get my SD card block working, but it's not mounting in Ubilinux. I'll have to try find a standard card.

  • Did you ever get a response to this?

    I'm having the same problem. I assume its because I don't have a correct library installed? I have both I2Cdev & MPU6050 libraries installed. Any help would be much appreciated. I'm busy trawling the internet now :)
