I'm trying to use Buildroot to create a linux image for my Banana Pi M2M. My issue is that when I power it up, the system hangs at "Starting kernel..." indefinitely.
Here is the log:

As there is no buildroot defconfig for the BananaPi M2M, I'm working from a modified olimex_a33_olinuxino_defconfig (Both boards use the Allwinner A33 processor). I am, however, using both the Bananapi_m2m_defconfig and sun8i-r16-bananapi-m2m.dts from u-boot.
My modified olimex defconfig:

The specific tweaks I made:
Changed the getty port to ttyS2 (the default debug uart for the m2m is uart2)
Swapped to the pre-existing uboot defconfig for Bananapi_m2m
Swapped to the pre-existing device tree file from u-boot
Redirected boot.cmd to an external package
Redirected post-build.sh and genimage.cfg to an external package
At the moment, boot.cmd, post-build.sh and genimage.cfg are unmodified copies of the olimex versions. I'll include boot.cmd for reference.
boot.cmd:
setenv bootargs console=ttyS2,115200 root=/dev/mmcblk0p1 rootwait panic=10 ${extra}
ext4load mmc 0 0x49000000 /boot/${fdtfile}
ext4load mmc 0 0x46000000 /boot/zImage
env set fdt_high ffffffff
bootz 0x46000000 - 0x49000000
I'm somewhat of a novice, so apologies if I've shared too much irrelevant information. If anyone has any insight I'd greatly appreciate it, I feel a little blind with the only output being "Starting Kernel..."
EDIT: I reverted the boot argument back to ttyS0 and it got over the initial hang. I'm not sure what part it's hanging at now, is it failing to run the Getty?

It's the value of .vd_version from corresponding version definition (ElfXX_Verdef in elf.h). For example:

I have one react native app coded with Ignite Red Boilerplate and app sometimes stuck at Launch screen (Splash screen) only. Then I go back to previous commit and start the app again, and it starts working as expected.
To help you to find out the solution:
I am using this splash screen module : React native splash screen
Ignite red comes with one Login Saga and I have added another signup saga, and it was working fine till the time I actual uninstall the app and reinstall it, and then when App get installed, it never pass the splash screen.
I am not seeing any log any where, tried to run it in Xcode as well but no debug log, how ever I can see following things in Simulator system log and I am pasting some things here. Hope some body can help me to decode it.

As you can see in system log, First 6 entries are my start up actions that are getting fired perfectly. And then this no connected handler.
You have an exception:
undefined is not an object (evaluating 'el.props.component')
Search your project for el.props.component - it's going to be a component which is mounted during start-up more than likely. Either that or you're misusing a 3rd-party component which has that code.
When I connect modem befour PC start all works fine. But when connect to working PC have bug.
Have no use any drivers from other place all work on default debian jessie repositories.

Have found this article:
In the good sequence, cdc_ether is loaded first and lays claim to the
device. The new eth1 interface is configured and all is well. After
doing some research, I decided to give something a go. What if we just
disabled the sierra driver? It seemed like this latest Sierra Wireless
device didn’t really need that driver as it could communicate via USB
CDC. What could it hurt? Nothing, I figured, so I opened up
/etc/modeprobe.d/blacklist.conf (don’t forget to invoke vi with sudo!)
and went to work. Here’s what I added at the bottom.
# added 2012-12-04 - prevent sierra USB driver from loading
blacklist sierra
I have tried to write a simple linux char device driver using this tutorial: http://matthias.vallentin.net/blog/2007/04/writing-a-linux-kernel-driver-for-an-unknown-usb-device/
I am using slightly newer device and slightly newer kernel. So I used their code changing product and vendor id and I am just trying to make kernel call probe function when device is attached which I failed to do looking at my /var/log/messages. Driver loads successfully:

The code I have that is responsible for making this association is:
#define ML_VENDOR_ID 0x2123
#define ML_PRODUCT_ID 0x1010
static struct usb_device_id ml_table [] = {
{ USB_DEVICE(ML_VENDOR_ID, ML_PRODUCT_ID) },
{ }
};
static struct usb_driver ml_driver = {
.name = "missile_launcher",
.id_table = ml_table,
.probe = ml_probe,
.disconnect = ml_disconnect,
};
My kernel version is 3.3.8
Any ideas what might be wrong?
BTW. I am completely new at this so it is very likely that I skipped some relevant information please ask me if something more is needed.
