Hi again,
The custom device tree configuration produce some errors on boot up. The
most significant errors are:
[ 2.360604] mtdoops: mtd device (mtddev=name/number) must be supplied
[ 2.719239] slave hdmi: could not get i2c
[ 3.279978] omap_vout:Could not register Video driver
[ 3.292445] sr_init: platform driver register failed for SR
[ 3.847739] systemd[1]: Failed to enumerate cgroup controllers: No such
file or directory
[ 15.711163] systemd[1]: Failed to start Load Kernel Modules.
[ 19.921960] remoteproc0: failed to load am335x-pm-firmware.elf

[ 100.760159] omap_i2c 4819c000.i2c: controller timed out
The problem seems to be related with I2C communication. The camera cape is
an i2c soc_camera and interacts through i2c-2 (bus 2).
Testing that bus communication I get a "controlled timed out" error. Is not
responding.
root@beaglebone:~# i2cdetect -r 2
WARNING! This program can confuse your I2C bus, cause data loss and worse!
I will probe file /dev/i2c-2 using read byte commands.
I will probe address range 0x03-0x77.
Continue? [Y/n] y
0 1 2 3 4 5 6 7 8 9 a b c d e f

-- [10859.600173] omap_i2c 4819c000.i2c: controller timed out
So, now I'm trying to wake up that i2c bus in order to activate the
communication with the camera cape. To do so I'm modifying the device tree
attached in the first comment.
Also added a 'new' cape instance in "am335x-bone-i2c2-cape-eeprom.dtsi"
with the sensor's information and deleted from the custom device tree.
cape_cam0: cape_vddn_cam@58 {
compatible = "aptina, mt9m114";
reg = <0x58>;
#address-cells = <1>;
#size-cells = <0>;
/* dummy pll flags m, n, p1-7, PLL hardcoded in Driver */
/*flags = <0>;
pll-divider = <0 0 0 0 0 0 0 0 0>;*/
};
Any help will be appreciated!
Sergi.
