Installing a Kernel Image With OSX

Insert the microSD in the SD adaptor and insert it into the SD slot on your Mac. You will get a popup warning saying The disk you inserted was not readable by this computer. Click Ignore.

Use diskutil to find the device name. Look for the 1GB disk with 4 Linux partitions. If you missed the instructions above and clicked Eject instead, it will not be listed here.

$ diskutil list
/dev/disk0

   3:                      Linux                         128.0 MB   disk0s3
   4:                      Linux                         128.0 MB   disk0s5

/dev/disk1
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *320.1 GB   disk1
   1:                        EFI                         209.7 MB   disk1s1
   2:                  Apple_HFS Macintosh HD            319.7 GB   disk1s2

In my case this identifies the device as /dev/disk0. Unmount the disk.

$ diskutil unmountDisk /dev/disk0
Unmount of all volumes on disk0 was successful

Copy the ROM image to the SD as follows:

1

sudo dd if=rom-chumby-falconwing-chumby-starter-image.img of=/dev/disk0 bs=8m

Be patient, this takes a while… like 6 and a half minutes in my case. Perhaps you would like to amuse youself by looking at pictures of cats?
