Hi Commies,

 

I am currently developing on a i.MX6SL-EVK with Android 6 and 3.14 Kernel version. For that I defined a cutom board configuration, added Murata BT/Wifi and a custom display driver for epd.

 

I am stuck at two points:

1. I cant get into fastboot mode. When I try to enter fastboot on u-boot, I get this message:

U-Boot 2015.04-14469-g9433975 (May 10 2016 - 13:16:27)

l.

 

2. I cant load my kernel module into the kernel on init. I get the following message:

 

init: Warning!  Service epdc_init needs a SELinux domain defined; please fix!
init: Starting service 'epdc_init'...
logd.daemon: reinit
init: Service 'logd-reinit' (pid 137) exited with status 0
init: cannot execve('/system/bin/epdc-start.sh'): Permission denied
init: Service 'epdc_init' (pid 144) exited with status 127
init: write_file: Unable to open '/sys/block/mmcblk0/queue/read_ahead_kb': No such file or directory
init: property_set("ro.ril.wake_lock_timeout", "300") failed
init: using deprecated syntax for specifying property 'ro.serialno', use ${name} instead

 

The same procedure worked on KK4.4.3, so I must have missed something on porting. Even insmod doesn't work.

 

Hopefully someone can help me out of this issues.

 

Thanks in advance.
