Permission problems on 3.14 kernel Android 6 - i.MX6SL-EVK

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)

CPU: Freescale i.MX6SL rev1.2 at 396 MHz

CPU: Temperature 30 C

Reset cause: POR

Board: MX6SLEVK

I2C: ready

DRAM: 1 GiB

PMIC: PFUZE100 ID=0x10

MMC: FSL_SDHC: 0, FSL_SDHC: 1, FSL_SDHC: 2

In: serial

Out: serial

Err: serial

Detecting VOL_DOWN+POWER key for recovery(0:0) ...

check_and_clean: reg 0, flag_set 0

Fastboot: Normal

flash target is MMC:1

Net: FEC [PRIME]

Normal Boot

Hit any key to stop autoboot: 0

=> fastboot

g_dnl_register: failed!, error: -19

exit not allowed from main input shell.

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.

Hi robertpohlink

EPD panels are no supported in official Android releases, please

refer to attached Release Notes Table 2. Features.

Recommended apply to fae or mss services for special support.
