I am currently designing my first system based on Sierra WP8548 chpiset and Legato.
I have two mangOH development kits:
- Old kit - Rev 2
- New kit - Rev 7 (Green (DV4))
With the first kit (old), after conducting some tests with my new firmware version (Make by my yocto project), I wanted to return to the default firmware.
=> From source.sierrawireless.com/resour … rerelease9, I downloaded the default WP75 Firmware Packages:
- Customer configuration: Generic (early sample), SKU: 9101011, Configuration: 001.014_000
- Carrier Configuration: SKU 1102734, Configuration 001.002_000
=> Result: Ok, no error (Kernel, filesystem and Legato apps).
Now, if I want to test my firmware, I can not detect my mangHO kit when it is in fastboot mode (sys_reboot bootloader).

Do you know how to get back with “fastboot” ?
Thanks for you help,
