i 've had a question about how to update firmware via serial service port
Ive got DM TWO for repair,
the symptoms are when i power up is yellow led,then white,then blue and at last red blinking.
i 've tried to boot it up from sd card (rescue image) but no luck
when i connect it via putty (serial connecton) i've got an image like in attachment.
is there any way to boot it up by any aplication because dreamup wont load a boot loader...
