We have two groups of mangoh Red boards WP7607, one from 2017/18, and a second one bought fall 2019. Overall 20+ units.
We are trying to update all of them to the last releases 12 or 13.
We’ve tried to update the last batch of mangoh that we bought. We have followed the procedure that worked in the old mangoh’s in our possession. This procedure consist in:
1- Update firmware by using swiflash command:
swiflash -i WP76xx_Release12_GENERIC_GCF.spk -m WP76XX
2- Make the mangOH image and update it to the board:
-
With this environment (The same as Release 12 has):
LEGATO FRAMEWORK: 18.10.3
TOOLCHAIN: SWI9X07Y_02.25.02.01 -
With this command and after perform LEGATO=1 make red_wp76xx:
update ~/mangOH/build/update_files/red.wp76xx.update 192.168.2.2
The procedure works fine in ALL our old Mangoh reds.
In the NEW mangoh red boards we are able to upgrade the firmware. But when we perform the update command the board starts a rebooting sequence ening up in a rollback, and we are not able to update the legato version. The result is that we cannot access to the sensors nor the redsensortocloud application.
As an alternative we also tried to upgrade the boards by using the leaf environment. And again it works perfectly on the old boards but we face the same rebooting problem in ALL the new ones.
So…
Is there any known difference between red production batches that may produce this problem?
Is there any way we can capture the logs generated during the failing reboot process?
Thanks a lot,
Enric
