Is there a way to recover Edison root password?
Also I've also tried to replicate the firmware recovery instruction below but to no avail.
-How do I monitor if Edison has entered into the firmware recovery mode? ("screen /dev/cu.usbserialxxxx 115200 -L" ?)
-Where's the UMIP header?
-How to "send new image over USB"
From the document "Intel Edison Kit for Arduino":
SW1UI3 and SW1UI4 are used to recover an Edison that has a corrupted software image. Powering off Edison and
then pressing FWR_RCVR and then applying power will cause Edison to go to firmware recovery mode. Edison will
be ready to receive a new image over USB. Two recovery modes are available depending on the state of the
SW1UI4 when power is applied.
During boot, If FWR_RCVR is high (button FW pressed), the processor attempts to load the firmware from flash
from the location specified in the UMIP header. During boot, if FWR_RCVR is high (button FW pressed) and
RCVR_MODE is low (button RM pressed), the processor attempts to download from USB-B port, regardless of the
UMIP header.
thank you in advance
