MangOH red board unable to update image

mangOH Red
21

Once the board boots up, microcom cmd is used to access the AT command port.

As recommended after flashing the 13.3 image on the board, the board is not rolling back to original FW after update, but it crashes and does not come up as i sent the logs earlier.

No idea as i don’t see crash on my board, maybe you can disable one line by line in red.sdef and see which line makes the crash

23

Can you let me know for the 13.3 version of the code, what is the legato, and mangoh versions used.

Currently, i am using legato 19.02 while the mangoH version is master one.

24

I think the same as you

25

Can you please reconfirm the version of legato, toolchain and mangoh version

26

please see here:

27

i have built the image as per the steps given here.

Can you guide me with the flashing steps too.
Just want to be clear abt the flashing steps too.

28
  1. transfer the ./build/update_files/red.wp76xx.update to module 's /tmp folder by scp.
  2. on module, use “update /tmp/red.wp76xx.update” to update the mangOH layer.
29

Ok, i did the whole step of building and reflashing as mentioned in the earlier conversations.

The crash is because of battery gauge mising.

You can try to remove that in the source

31

Finally was able to build and get the red board booted with the image built.

Thanks for all the support.

I will be raising another query for Talon + mango redH board.

32

hi ,
Any one tried of creating a new at command in application .e.g., at+sample is the Customized input command and output for the command is Success. Any example can any one guide me how to create a new command

33

you can see this sample which has created AT+TEST and AT+BRIDGE:

34

Hi,

I have created custom at commands and relevant inputs for those commands and all working with sockets.

the same default application, atServerTest.c supports both socket and uart mode of accepting commands.

Let me know where u r facing issue. If you have compiled the app, push to the board and install and run the inital commands in the file.

Regards,
Tejaswi

Hi, Main aim of building and flashing the MangOH board was to test Talon Mirage IoT card. Downloaded 192.168.l.254 the MangOH source, Legato source and …
