Re: Change Qt version on Jethro

I made a lot of changes in the device tree and kernel configuration, so I prefer to maintain the Jethro version. To change from Qt 5.5.1 to Qt 5.7 I moved meta-qt5 to morty branch and rebuild the image. I'm able to obtain and image that work, but all Qt5 demos give me a segmentation fault. E.G.: cd ...

Change Qt version on Jethro

Hello,

how is possible to change the Qt version of Jethro distro from Qt 5.5.1 to Qt 5.8 ?

Marco.

Is there the possibility to use the UART2, actually used to communicate with bluetooth without any hardware modifications ?

Thanks,

Re: SOM reset issue

I verified the 3.3V SOM INPUT and there aren't voltage dip when reset occurs. I performed some tests with different configurations, but I can reproduce sistematically the issue only with one carrier that integrate your "QC7" SOM. The same carrier with "QC4" SOM doesn't reset, and...

Bluetooth UART

Hello,

I need to use the UART2 to connect an exeternal device, how can I configure it in order to enable it ?

Actually, I disabled the /etc/init.d/variscite-bluetooth, but the UART2 doesn't work.

Re: SOM reset issue

I can reproduce the reset using the evtest application and moving the mouse: evtest /dev/input/event0 I can't test your v70 SD card image on my board because my SD card reader is mapped on a different PIN on the SOM, so u.boot can't see the "card detection" PIN. Any idea in order to avoid ...

Re: Enable output in standby mode

On the normal power mode my application set a GPIO as OUTPUT and set it to ENABLE (level 1). I need in some case to set the SOM to "standby mode" but keeping this GPIO to ENABLE condition in order to maintain some peripherals powered. Is it possible ? Actually,what I noticed is that when I...
