Hey @nite , sorry for the delay, this fell through the cracks… I’m guessing that you are on Mac, right? You have to point the target not to the mounted partition, but to the whole disk, which is
/dev/diskX, for example
/dev/disk2. Take the disk’s name, and then
rdt configure /dev/disk2
You can find which disk it is by using the Disk Utility, for example (see
Device in the lower right corner):
Alternatively you can use the settings Storage menu (I think that’s the name), or Etcher to show you the drive’s path to use.
The mounted partition,
/Volume/resin-boot would actually refer to
/dev/diskXs1, the first partition on the disk, and not the location to point rdt to.
