  1. It must be easy, but unfortunately the TV is not very new, and have not this menu items (((
  2. Thanks for the reply, but I use HDMI, did you think this will work?
  3. Hello! I think the level shifter is not needed, because SDA and SCL on the LCD is inputs and did not have potential to kill CPU. Just connect directly to bus and give +5v on vcc pin. I have tested, and no problem.
  4. Good day! I have the same problem on my Samsung plasmaTV in HD (720p native) and other modes. I read all topic, i tried to change all possible config's but still have overscan problem. Does anybody has solution ?
  5. In boot.cmd Try to modify setenv bootargs "console=ttyS0,115200 console=tty1 root=/dev/mmcblk0p ............." to setenv bootargs "console=tty1 root=/dev/mmcblk0p .............." and don't forget to recompile # Recompile with: # mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr
  6. Good day! I found some oddities with UART port driver. If I change the speed or the number of bits in the transmission, then everything works fine. But if I try to set the parity it does not sets. Not work modes: "EVEN, SPACE, MARK". Normal works only "NONE". Anyone faced similar problem? Tested under minicom and Java prorgam. The same result. p.s. I mean this modes sets only logical and does not sets physical. The device on other end always reports parity errors.
  7. Additionally, the already modified source files: https://drive.google.com/open?id=0B-_e-jRDz7k0U1JUcWJFenRXSkk Hopefully, the archive file is available.
  8. I want to apologize, I thought that nobody interested in my modification, because the topic is stalled. If I make a patch file be enough? --- w1/w1.h 2016-07-02 20:09:37.000000000 +0500 +++ w1.mod/w1.h 2016-06-12 19:36:58.000000000 +0500 @@ -52,6 +52,7 @@ #define W1_CONVERT_TEMP 0x44 #define W1_SKIP_ROM 0xCC #define W1_READ_SCRATCHPAD 0xBE +#define W1_WRITE_SCRATCHPAD 0x4E #define W1_READ_ROM 0x33 #define W1_READ_PSUPPLY 0xB4 #define W1_MATCH_ROM 0x55 --- w1/w1_io.c 2016-07-02 20:09:37.000000000 +0500 +++ w1.m
  9. Yes it has... But you need to work a little soldering. Here are 2 contacts on the spot D48 is reset. They only need to shut between them.
  10. Yes, I understand about button, As I say shutting the capacitor (that means shut to VCC as on scheme) not to GND, is not working...
  11. Hello! Why if the device boots without eth0 physical link connection, and than when physical link is established, device do not get dhcp metric automatically, and network services needs to be restarted?
  12. It works!!! You just need to set 3.3v on transistor "collector" (pin 3) and that will reset the board!!! zador.blood.stained Thank you very much again!!! p.s. short circuit of C301 is not working (I don't know why)...
  13. zador.blood.stained Thank you very much! Now I know where the reset circuit!
  14. Sorry, I didn't know how to provide a patch to current driver or as a git pull request. I will try to sort out this issue... > Since I am not an opensource law specialist, don't take this tip as 100% proper way. I'm not an expert too, so decided to ask I can make the patch file and do the driver files, which can be simply replaced in the system to verify. But I understand that this forum does not allow attachments to messages or I am not right?
  15. Good day! I have made modifications to the kernel driver for the temperature sensor Dallas ds18b20 on w1 bus. Slightly corrected timings, have achieved stable operation of sensors with parasitic power, and also added the option of changing the resolution. Now you can easily set 9,10,11 or 12bit resolution, by a simple command "echo 9..12 > /sys/bus/w1/devices/28-xxxxxxx/w1-resolution". Accordingly, when you lower the resolution significantly decreased the response time of the sensor from 1100ms (whith 12bit) down to 125ms (with 9bit). My question is can I post here the modified s
