Erasing the flash memory
If you have problems with your Juno software and have to completely reset the images in flash you must
erase everything that is there first. It is good practice to do this when applying a recovery image or
moving to a new Linaro release in case any configuration requires changing. The following steps assume
that the V2M-Juno motherboard is connected to a host computer.
1. At the
Cmd>
prompt on the serial terminal, issue the command
flash
.
2. The V2M-Juno motherboard will power on automatically and there is a brief delay while the V2M-
Juno motherboard firmware initializes.
3. At the
Flash>
prompt, enter
eraseall
.
4. Once the V2M-Juno motherboard firmware has finished erasing the flash memory, at the
Flash>
prompt, enter
exit
.
5. The V2M-Juno motherboard powers down and returns to the
Cmd>
prompt.
On the subsequent boot, the V2M-Juno motherboard firmware copies images from the SD card into the
flash memory, following the definitions in the
images.txt
file. You should see the following:
Cmd> flash
Switching on main power...
PMIC RAM configuration (pms_v104.bin)...
IOFPGA config: PASSED
Flash> eraseall
