I am having some problems with flashing the mangOH Green using swiflash.
I am following the instructions from http://source.sierrawireless.com/resources/airprime/software/swiflash/
However, I never see a /dev/ttyUSBx device appear on my development machine, can you offer any suggestions?
I ssh into the mangOH Green then tell it to enter the bootloader.
root@swi-mdm9x15:~# microcom -E /dev/ttyAT AT!BOOTHOLD
This appears to work, as the ssh connection goes dead. I can also achieve the same thing by setting switch 7 on the microswitch array.
However, I never see the mangOH appear as a USB serial device and register with Linux.
I am connecting to the micro USB port on the mangOH (labelled PRIMARY CF3 USB).
On my development machine I see the following:
trj@dev:~$ lsusb Bus 002 Device 030: ID 1199:68c0 Sierra Wireless, Inc. trj@dev:~$ dmesg [20795485.867906] usb 2-1.1: new high-speed USB device number 30 using ehci-pci [20795485.961432] usb 2-1.1: New USB device found, idVendor=1199, idProduct=68c0 [20795485.961445] usb 2-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [20795485.961452] usb 2-1.1: Product: WP8548 [20795485.961457] usb 2-1.1: Manufacturer: Sierra Wireless, Incorporated [20795485.961463] usb 2-1.1: SerialNumber: 0123456789ABCDEF
I have setup the udev rule to stop the device being grabbed by other systems.
trj@dev:~$ sudo swiflash -m WP85XX -i ~/1102816_9905383_WP8548_07.10.04.00_00_Generic_001.006_000-field.spk [ERROR] No ttyUSB ports detected; please make sure your device is connected and the udev rule is enabled, or try to power cycle the device.
If it helps, these are the details of the board I am using:
