itdb_test.py ERROR

[JMdroid]

Hello itdb_test.py file to run I get the following error:

ERROR: could not insert 'fbtft': Exec format error Traceback (most recent call last): File "itdb_test.py", line 11, in ensure_fbtft() File "/home/pi/fbtft_test/fbtft.py", line 58, in ensure_fbtft sudocall(["modprobe", "fbtft"]) File "/home/pi/fbtft_test/fbtft.py", line 16, in sudocall raise OSError OSError

Why?

[notro]

Use dmesg to get more info about the error.

[JMdroid]

I executed again and sent you the last record that has given me the dmesg command

[notro]

Have you built the kernel or modules your self?

There's a version mismatch between the kernel and the module fb_sys_fops which fbtft depends upon.

[JMdroid]

I have not built the kernel kernel version I am using is the 3.6.1 +

  image I am using is the 2013-05-25-wheezy-raspbian-2013-07-07-fbtft.zip and have upgraded later with rpi-update repository.

[notro]

rpi-update can't be used. It overwrites the kernel/modules with one that doesn't have support for the FBTFT drivers. I'm currently working on a solution where rpi-update can be used against a different repository which has FBTFT support.

[JMdroid]

I'll try with other previous images and see if it works

[JMdroid]

hello

probe to build an image and included the driver as you indicate in the Repositori fbtft and it has worked perfectly both ITDB adapter as the SPI circuit but with the latter I can not put touchpanel works that are malformations of the screen image. Why?

[notro]

Which display do you have working? And you have successfully tried both parallel and SPI interface modes?

• [url=https://github.com/notro/fbtft/wiki/SPI-interface-circuit]SPI interface circuit[/url]

Does the screen become garbled when you use the touchpanel and the SPI-interface? Excatly what do you do that corrupts the displays?

[JMdroid]

I use the screen wil itdb02-2 .. 8 "itead study" http://imall.iteadstudio.com/display/tft-lcm/im120419009.html

I work two parallel modes as both spi

to use the parallel mode "LCD PI Adapter Kit" "itead study" http://imall.iteadstudio.com/im130425001.html

spi mode to use the circuit you propose in the repository fbtft https://github.com/notro/fbtft/wiki/SPI-interface-circuit

but to put to work the touchpanel and the screen is when the image begins to distort

[notro]

but to put to work the touchpanel and the screen is when the image begins to distort

I haven't experienced this myself nor had any reports about it.

Does this happen both with the SPI circuit and in parallel mode?

Does it happen without the touch driver (ads7846) loaded?

In SPI mode with the touch driver loaded, does evtest give any output when you touch the panel?

sudo apt-get install evtest
evtest

evtest will list the available input sources. With the touch driver loaded, ADS7846 will be in the list.

The touch panel won't work in parallel mode with that Adapter kit, because the touch controller isn't wired to match up with the Raspberry Pi SPI interface.

[JMdroid]

I have it connected to the SPI circuit and works well the visualization of the display and touchpanel but touchpanel touch the finger is when you start to distort the screen.

evtest is installed and the ADS7846 driver is loaded.

[notro]

I'm sorry but I don't know what may cause your problem. Here is a similar problem on another display: http://www.raspberrypi.org/phpBB3/viewtopic.php?p=392342#p392342

[JMdroid]

thanks for your help

will try to locate the failure to give a solution and I will give to the problem commented
