Seems a bit odd that you do not have permissions to create files in build directory. Did you setup environment with sudo or a different users?

3

I set up with sudo …my system wont run the source setup…x without sudo

I set up with sudo …my system wont run the source setup…x without sudo

Then that is the problem to solve first. It is not allowed to use sudo in any of the commands.

I do not know what would case this command:

source setup-environment nxp

To get permission errors.

sorry man
sprinter@mercedes:~/Dev/IMX/Picoboard$ source setup-environment nxp
Configuring for imx6qsabresd
mkdir: cannot create directory ‘/home/sprinter/Dev/IMX/Picoboard/nxp/conf’: Permission denied
Error: Cannot write to /home/sprinter/Dev/IMX/Picoboard/nxp, perhaps try sourcing with a writable path? i.e. . oe-init-build-env ~/my-build
sprinter@mercedes:~/Dev/IMX/Picoboard$

it has something to do with user accounts …i cant run source without sudo ,maybe i need to add user account or something

6

Hm, it looks to me like your are not running the setup-environment file provided by meta-mender-community

7

What do the following commands show?

$ id
$ ls -l /home/sprinter/Dev /home/sprinter/Dev/IMX \
      /home/sprinter/Dev/IMX/Picoboard \
      /home/sprinter/Dev/IMX/Picoboard/nxp

I had problems with my user permissions
sudo chown $USER:$USER ~ -R

did the quick fix …now its compiling smoothly thank you everyone

Can you disconnect and reconnect the USB OTG cable while viewing the system logs on your build host? I’m not sure which specific file for your host but on Ubuntu 18 it’s /var/log/syslog by default. It seems like your board is not being enumerated on the USB bus on your host.

I am able to list the device via lsusb and dmesg
sprinter@mercedes:~/Dev/IMX/Picoboard/mender-nxp/build$ lsusb

I had earlier flashed android things on it using googles tool and I can view see it when i view the logs
more /var/log/syslog or dmesg ,lsusb

14

Is the format of your imx_usb.conf correct, as it doesnt match the format i’m using?

#vid:pid, config_file

0x15a2:0x0054, iw-spl-usb.conf

0x0525:0xb4a4, iw-uboot-usb.conf
