What do you mean by reboot? It was booted after sd card inserted after replacing script.bin on PC. M ...

Well, there is more than one way to replace script.bin and not all require to take out SD card. Anyway, try with 0xB24D instead of 0x4D.

I don't think there is another one. You may try another key. From what I know, it doesn't need to be KEY_SLEEP. For me, it works as KEY_POWER, but you can try also KEY_0 or any other. As last resort, you can backup lircd.conf and try from scratch again. Did you make some other script.bin change too?

Is lircd.conf read during boot? If not, key mapping should not matter. I guess the only requirement is to have hardware in sleep state and make neccesary script.bin changes. Abd then device should wake up, right? Or it's also related to lirc config as well?
Maybe only some amount of codes are supported? Should I try with other remote?

Not in the driver, but systemd service load it, so yes, it doesn't matter. I partly reverse engineered ARISC IR driver and I can tell you that it looks almost the same as original Allwinner IR driver. I would say that codes don't matter really.

Definetly try with another one, as long as it outputs NEC protocol.

I'd be interested in knowning those other ways as I just installed everything on the build-in emmc and I think changing the script.bin might be a pain now :S

First make flash folder writable:
  1. mount -o remount,rw /flash
Copy code
and then copy script.bin with scp, for which you have to have ssh enabled. For example, on host PC for command line tool on Linux:
  1. scp script.bin root@192.168.0.10:/flash
Copy code
For Windows, there is graphical tool WinSCP.

Thanks a lot!
I'm using a samba share to copy to my windows pc already hehe.
Cant wait to have sunxi tools are included in the build, I won't be needing to go back and forth  Kodibox -> Window PC -> Linux VM -> Windows PC -> KodiBox

glaur500,

Unlike mine,  your lircd.conf indicates that the key streams are not of a constant length. Please follow these instructions so we can find out what your remote is sending out:

1. Connect to the board through SSH.
2. Kill the lircd process and record just the stream for the POWER key like this:

  1. killall lircd
  2. irrecord -f test.conf
Copy code

3. Follow the instructions carefully but record just the POWER key.
4. Once you're done copy the 'test.conf' file out through the Samba share (or a USB pen drive) and post it here.
5. Reboot the board from the SSH prompt (type 'reboot' and press ENTER) to restart everything again (just don't unplug it without any kind of controlled shutdown).

This is the file I got:

  1. begin remote

  2.   name  test.cfg
  3.   flags RAW_CODES
  4.   eps            30
  5.   aeps          100

  6.   gap          129815

  7.       begin raw_codes

  8.           name KEY_SLEEP
  9.              9040    4528     552     560     576     560
  10.               528    1728     544     608     504     624
  11.               536     568     568     584     504     632
  12.               528     568     576    1712     536     560
  13.               576    1696     552    1704     520    1728
  14.               544     608     504    1728     576     560
  15.               520     616     552    1696     520    1728
  16.               576    1704     544     568     568     568
  17.               520     632     528    1704     520    1728
  18.               576     576     504     616     552     560
  19.               576    1696     552    1704     520    1728
  20.               568   75543    9016    2256     576
Copy code


What's represented are times in microseconds for logical level pairs (one followed by zero). So the first two are the header and the next read as (check the NEC protocol definition on the first post):

0 0 1 0 0 0 0 0 = 0x20
0 1 0 1 1 1 0 1 = 0x5D
0 0 1 1 1 0 0 0 = 0x38
1 1 0 0 0 1 1 1 = 0xC7

The last line is the time until and the key release and can be ignored. This is where those codes in my 'lircd.conf' are coming from. Please share your file so we can find out why your remote is not recognized.
