Hey everyone!

I tested Lindenis with imx317 module and it works good, but we're currently trying to make it work with "ov2718" and it doesn't work.
I compiled ov2718_mipi.c driver, it correctly loads into kernel and even able to read/write to camera's i2c address but when I run 'ldcam -c -d 0 -o out'  it freezes with the following dmesg errors:

I ried to build sdk with choosing builadroot as OS,but I get a fail of not finding buildroot.config.
So does Lindenis sdk support buildroot yet?
$ source build/envsetup.sh
All available platforms:
  0. eagle(Allwinner-V5,sun8iw12p1,arm)
  1. petrel(Allwinner-H3,sun8iw7p1,arm)
  2. cuckoo(Allwinner-V3,sun8iw8p1,arm)
Choice: 0
All available OS:
  0. buildroot
  1. debian
Choice: 0
  0. allwinner-dvb
  1. lindeni-v5
Choice: 1

During the work with one camera VI_CHN_0 which corresponds to MIPI0 input is used.
It is possible to learn compliance of VI_CHN_x to physical inputs?

Is there a image or basic rootfs available with glibc >= 2.27? As the current version of the image and the basic rootfs is 2.24.

Hello,

When I run the examples the console is printing a lot of information. Is there a way to disable this? As I don't want to spam the console with debug messages.

Hi all.

i build  the image form lindeni sdk.
finally i got the next log:

THEN! i flash lindenis image, and everything was fine!!
then i flased my image again, and EXT4-fs error appeared again!

can someone help me?

Hello,
 
I currently have two Lindenis V5 boards and I want to understand the boot process a little bit more.
From Allwinner documentation, I understand that there’s so called FEL pin which either boots motherboard normally (depending on BOOTSEL flags) or enters UPGRADE mode (USB or UART).
 
So can you please help me with the following questions:

1. Where this FEL pin is located? I can’t find it in schematics.
   
2. How to enter UART upgrade process instead of USB? I want to try it out.
   

Just google it! Google your friend LOL

1) i build the image using lindenis SDK
2) i flashed the lindenis board using phoenix app
3) AND no more output is seen on the uart-putty console after "Starting Kernel..."


what's wrong??

p.s.: 

uart0 log:
