Firmware upgrade fails on mangOH green with wp7603


#1

Hi ,

I have some question about firmware upgrade.
I need to build a custom image including kernel and rootfs and upgrade it on my mangOH Green board because we may need to upgarde amount of boards in the future. So I need to upgrade the whole image NOT only the apps.

I had referenced some page such as swiflash and swicwe web pages.
Env: In the VM in ~/workspace2/legato/ , repo is git://github.com/legatoproject/manifest

I enter command “make wp76xx” and it build some image like legato-squashfs.4k.ubi.cwe and legato-squashfs.2k.ubi.cwe.I check the board I think it is 4K block size, so I use cmd "swicwe -o wp76xx_4k_image.spk -c build/wp76xx/legato-squashfs.4k.ubi.cwe " to make a .spk file.ThenI use cmd “swiflash -m “WP76XX” -i wp76xx_4k_image.spk” to upgrade it into target.It shows

Detecting USB of the target
DONE
Communicating with the target
DONE
Switching to firmware download mode
… (…loop, and do nothing)

And if I unmount USB and enter cmd “fwupdate download wp76xx_4k_image.spk 192.168.225.1”,
it shows

root@192.168.225.1’s password:

But I check the fw version it is wrong.

In VM :

How do I upgrade the fw correctly? Is the file legato-squashfs.4k.ubi.cwe is the right image I need?

Another question, are all docs in mangOH green/sierra wireless/legato introducing firmware upgrade that guide us just upgrade the apps?If it is yes, maybe I misunderstand the meaning of fw upgrade and should open a new topic to ask how to build a image(rootfs,kernel, custom data).

Thanks,
Neil

Hi,

Seems legato-squashfs.4k.ubi.cwe is only the legato framework image.
You can check whether “legato version” changed after you flash the new image.

About another question, I think I really download wrong distribution . I find the linux distribution in https://source.sierrawireless.com/resources/airprime/software/wp76xx/wp76xx-firmware-release-5-components/

I will try this first, thank you ,gays.
