Hi,

I have a mangOH Red with WP7504 with the latest firmware from Sierra Wireless.

> Device: WP7504  
> IMEI:  
> FSN:  
> Firmware: SWI9X15Y\_07.12.14.00 r34472 CARMD-EV-FRMWR1 2017/11/29 18:24:42  
> Bootloader: SWI9X15Y\_07.12.14.00 r34472 CARMD-EV-FRMWR1 2017/11/29 18:24:42  
> priIdPn: 9905087  
> priIdRev: 01.09  
> skuId: 1102710

I’m wondering if it is possible to use Legato version 18.04.0 with this? Officially the documentation supports 16.10.4, which is what I’ve been using until now. When I upgrade to 18.04 I’m able to perform an update on the device but it reboots multiple times and goes back to 16.10.4.

It should work fine.

Did you follow the getting started guide?

Yes, I did. The problem is that the device resets multiple times after I update from 16.10 to 18.04 and then somehow goes back to 16.10. Is there a built-in rollback mechanism that I’m not aware of?

How are you powering the device?  
can you run  
cm radio

I wonder if you are jumping to a 2G network and if your computer doesnt have enough juice to power the device.

Powered through USB.

> RAT: UMTS network (LE\_MRC\_RAT\_UMTS)  
> Status: Registered to a roaming network (LE\_MRC\_REG\_ROAMING)

Is there another way I can power the device?

signal strengh looks week too.  
Yes, you can power through a USB wall adapter. Just power through the console USB. Adjust by looking at step 3.3.4 on Getting Started guide.

So I used a 5V USB wall adapter to power the board through the console USB, but even though the PWR Led is on I can’t connect to it through the CF3 USB. I’m afraid the board is damaged?

I’m using a second mangOH Red board now. I updated the firmware and Legato. After updating Legato I noticed this in the console log. I don’t know if it’s relevant but it could point to something

It then reboots multiple times and goes down to 16.10.

Appreciate your help with this.

It looks like your toolchain doesn’t match the linux version that’s on your target.

Thanks @dfrey, I was using an older toolchain that was installed on my computer. Switching to the new one fixed the problem.

@asyal, I’m using a native Ubuntu 16.04. dfrey’s observsation helped me fixed the issue. Thanks for the help.
