I am working on Colibri IMX6ULL with 256MB V1.1A device. I have customized OS using bsp2.8b6(without graphical interface) and its working from last 3-4 years. Now I have observed issue : Whenever power off ( “poweroff”) command is run over shh the device reboots. Expected to go into the power down mode but found to be reboot.
I have also flash device with reference image from bsp2.8b6 but, still the issue persist.
The customized OS and reference OS found to be working with other devices properly for power off command usage.
Also I have flashed IMX6ULL device with latest OS from 6.0.0 & 6.3.0 on this two particular module, on power off the device not getting restarted, So the issue is seems to be resolved with updated OS.
But we are still using bsp2.8b6, and other devices found to be working with this bsp2.8 no reboot issue found but these two devices are found to be restarted issue
Below are the serial numbers details of modules.
- 07250746 - power off command not working with this module
- 06823473 - power off command not working with this module
- 06396478 - power off command Working with this module( For reference)
So, I just want to know that is there any hardware changes done on above not working module?
Please let me know suggestions if any
