[daiane_angolini]

dharmeshkanzariya‌, can you, please share what you have already tried? What is the kernel version you are using?

Artur is right, the WaRP7 community is being maintained in this site WaRP7 - The Next Generation IoT and Wearable De... | element14 | Design Center

hi my kernel version is 

4.1.15-gc45e62f-dirty
#6 SMP PREEMPT Tue Jul 12 14:44:15 CST 2016.

i have tried  nano /etc/wpa_supplicant.conf

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
update_config=1
network={
ssid="abc"
scan_ssid=1
psk="87654321"
priority=5
}

my laptop is connected to wifi name "abc" and my password is 87654321.

after that i tried ping google.com. but it didn't work

[daiane_angolini · Accepted solution]

Have you tried the procedure from WaRP7-User-Guide/Use_Cases.adoc at master · WaRP7/WaRP7-User-Guide · GitHub  already?

You are not going to ping google.com directly, you need to make sure you have configured a DNS server and you have Internet connection. At first, try to ping your local PC IP instead of an external DNS.

hi when i run this command i get this error.

root@imx7dwarp7:~# ifconfig wlan0 up
ifconfig: SIOCGIFFLAGS: No such device

is yocto image is necessary??

[daiane_angolini]

No, it's not. But you have to install the wifi module properly.

You can also try buildroot, master supports warp7

[dharmeshkanzari]

hi thanks . but i followed steps as you described

and  how to buildroot in warp 7??

[daiane_angolini]

The instructions from the User Guide use the yocto project image which includes the wifi firmware, the wifi driver modules, and wpa-supplicant package. You can use any rootfs if you know those pieces are included in the rootfs, it does not need to be yocto or buildroot. However, I really recommend you use or yocto or buildroot as we know they are working.

[dharmeshkanzari]

waiting for your response

[daiane_angolini]

I'm sorry for my delay. I was busy with unexpected interruptions.

You can download fsl-image-machine-test, last time I tested it included the wifi firmware properly.

[dharmeshkanzari]

hey thanks for your support.

i have downloaded  FSL Community BSP 2.2       xwayland

fsl-image-machine-test-imx7s-warp-20161124-6.rootfs.sdcard.gz

can you tell me how to update image into warp7

[daiane_angolini]

Please, take a look on User Guide, there is instructions to update yocto image, only u-boot, only kernel. A lot of tutorials.

And please, if you find any issue, please create an issue in the github so we can detail it.

GitHub - WaRP7/WaRP7-User-Guide: WaRP7 User Guide Source. For binary releases go to the release tab 

[dharmeshkanzari]

hello! thanks https://github.com/WaRP7/WaRP7-User-Guide/blob/80cc2de13a2dc21466a6ad9eedf4c5a143763dad/06-Chapter/Y...

when i write command 

ums 0 mmc 0

on i.mx7 terminal. it said command not found. 

can you help me??

[fabio_estevam]

Make sure you use an updated U-Boot version. You can use the latest 2016.11, for example, as it will contain the "ums" command.

Then you can load it via USB when the board is in Serial Download mode.

[daiane_angolini]

Please double check if you really don't have ums command on your u-boot. It's not an expected behavior.

Anyway, you can update u-boot by:

WaRP7-User-Guide/U-boot.adoc at master · WaRP7/WaRP7-User-Guide · GitHub 

and make sure you are aware of

WaRP7 possible brick and solution - i.MXDev Blog 

[dharmeshkanzari]

hello! actually i don't know how to open uboot terminal. i opened it and write

=> ums 0 mmc 0

then in ubuntu i operated operations 

fsl-image-machine-test-imx7s-warp-20161124-6.rootfs.sdcard.gz
dharmesh@dharmesh-HP-Notebook:~/a$ gunzip fsl-image-machine-test-imx7s-warp-20161124-6.rootfs.sdcard.gz

dharmesh@dharmesh-HP-Notebook:~/a$ 

after reboot. it has not yocto image

[daiane_angolini]

Here:

dharmesh@dharmesh-HP-Notebook:~/a$ sudo dd if=fsl-image-machine-test-imx7s-warp-20161124-6.rootfs.sdcard of=/dev/sdX

Are you replacing the *X* from dev/sdX to the right device number/letter?

[dharmeshkanzari]

how to find true *X* ?? 

[daiane_angolini]

Use dmesg.

type "dmesg" see the last lines. Then plug the sdcard, dmesg again and see the last line has changed. The last log shows the /dev/sdX kernel create to your sdcard.

after running that command. i didn't get login
