firmware update: mfw-nrf9160-1.0.0-25-rc2.prealpha

[Hoang]

Dear, 

I am using ncs_v1.0.0_rc4, and got the FW mfw-nrf9160-1.0.0-25-rc2.prealpha from Bjørn Kvaale.  I want to update this FW

mfw-nrf9160-1.0.0-25-rc2.prealpha.zip

I tried to use nRF Connect v3.0.0 Programmer 

/Cellular modem/ Update modem. But it didn’t work

Modem DFU failed with error: Error: Error occured when program. Errorcode: CouldNotCallFunction (0x9) Lowlevel error: Unknown value (ffffff5e)

How can I do it? Can I use nrf9160_mdm_dfu –update ?

 

Thanks

Mvh

Hello Hoang!

I can confirm that this fails on my DK aswell. Is it any reason you're not using the newest modem firmware available? It can be found at this location.

All the best,

Dear Carl, 

I am testing ncs_v1.0.0_rc4 - I want to get the real position when I run asset_tracker. With ncs_v1.0.0, the positions are not my

Hello again!

The newest modem firmware have support for real GPS data, so you should definitely update, regardless of your NCS version.

Furthermore it's true that ncs_v1.0.0 doesn't support real GPS in the asset_tracker, but this is also true for ncs_v1.0.0_rc4. 

You should check out this pull request for NCS. It's the only example I can find where asset_tracker uses real GPS data.

All the best

Hello!

Did you fetch the pull request code correctly before building and flashing? It can be done with the following commands(inside <ncs_path>/nrf):

git fetch origin pull/943/head:new_branch

git checkout new_branch

git pull

west update

The new_branch can of course be a name of your choosing. 

Hope this helps!

Hi Carl, 

I pull down the git from 

joakimtoe/fw-nrfconnect-nrf

then, tried asset_tracker, but i got error: 

     sched_priq.h: No such file or directory

This is the wrong branch of the repository, you are supposed to be on the branch pca20035_to_master. Did you try to follow the commands I posted earlier? That should be the easiest way :)
