Quoted from PaulCoff:Thanks. I’m using a Mac. Which file should I have a the top of the driver? There are two files,right? I also format the thumb drive before I install code. If been using 32 and 64 size thumb drives. Thx
Mac DiskUtility is a bit of flake when it comes to doing this authoritatively - they keep changing the UI - I prefer using Window's disk utility, but either work if the right settings are used. You want to ensure the disk is formated fat32 and with a Master Boot Record format (MBR). On Mac Can use diskutil to erase and format the drive or cmd line
diskutil list
(to find the device addresses for the drives ex: /dev/disk3 )
sudo diskutil eraseDisk FAT32 MBRFormat /dev/disk3
(change /disk2 to the location of your usb drive as found in the list command)
You want all the stern spk files on the top level of the drive.. not in folders. So extract the zip file on your computer, then copy the contents of the zip (not the folder your zip program probably created to contain the files) to the USB drive.
I suggest formating the drive to 16gigs or less. Easy to do in the GUI, but the command line should be something like this when creating the partition instead of using the whole disk (as the above example)
diskutil partitionDisk /dev/disk3 MBR "MS-DOS FAT32" CODE 16384M free "" 0B
Would create a 'CODE' partition of 16gigs and leave the rest of the disk freespace.
