5 years ago Raspi zero should definitely support hard float abi. But if that is giving grief, you can try removing the directive from line https://github.com/juj/fbcp-ili9341/blob/7fd16bf60a4f87a7e497fe38e6862c50132f70f5/CMakeLists.txt#L49 . Delete CMakeCache.txt after editing the line for good measure, sometimes old options linger around in the cache file.

5 years ago Btw for raspi zero DMA will be critical, otherwise the driver will consume so much cpu that other processes starve. (Disabling DMA would require lowering display update FPS to 5 or 10 refreshes per second)

5 years ago Thanks so much for the awesome project and help w/ the hard float abi settings.
I hear you that "dma will be critical" but I don't know what to do with that information. Sort of feels like the documentation or the configuration script should be detecting raspi zero and then setting DMA to something appropriate rather than just leaving it to end user confusion. I don't know what the correct setting here is, which is why I took a stab at something. Could you perhaps suggest a range(or setting) that's valid? I get the feeling from your suggestion that mine is wrong, but without your experience i don't even know if I should be setting it higher or lower.. I'm all ears tho.. what's the right thing here? ( Suggest the script and/or documentation detail what it should be, sorry if I missed it.)

5 years ago I mean instead of -DUSE_DMA_TRANSFERS=OFF, use -DUSE_DMA_TRANSFERS=ON, that will enable DMA. (also not specifying that directive at all will enable DMA, but need to delete cmakecache.txt or it will just reuse the OFF setting if it had been specified on the command line before)
The build script should detect Pi zero automatically, the ARMv6Z directive should not be manually required either.

Which I don't understand because I'm using -DSTATISTICS=OFF but I'm getting further.
Thanks again for the great project and your awesome support on all things LCD related. That said, I think the 'RPI zero' build process may need some attention. I'll happily give you whatever details I can about the environment I'm building on to help you replicate. The RPiZero and the new 1.5inch LCDs are a pretty sweet little package that I hope someday I can use.

5 years ago Which OS was this on? What does ‘gcc —version’ give? Perhaps this is Pi zero on raspbian buster that updated GCC (have not tried that combo, only Raspbian Stretch on Pi zero)

This is a pi zero W device running kali downloaded from here: https://www.offensive-security.com/kali-linux-arm-images/
Specifically the "Kali Linux RaspberryPi Zero/Zero W" image.
Kali is based on debian and keeps up with the stretch train so I wasn't expecting too much chaos, but then again, mebe this is an issue.
The reason I'm using this distro instead of raspbian native, is that I need the monitor grade wifi drivers in Kali to display the data on the LCD that I got it for in the first place. (I'm trying to make portable, easily deploy-able rogue AP detecting units that staff can use to find rogue APs that are in the building.)

5 years ago I think that distro has a newer version of gcc than stretch has, hence the extra warnings. It can also be that it is configured differently, not sure if it might be possible for the distro to not use hard float abi at all, although why the asm code does not compile is something I have no answer to. Pi zero certainly has the rev16 instruction.
Perhaps it may be that in Kali one has to specify some other extra compiler flag to target ARMv6Z, though I don’t know what that might be.

5 years ago I really want this to work on the RPI zero W under kali..
I tried the following:
cmake -DST7789VW=ON -DGPIO_TFT_DATA_CONTROL=22 -DGPIO_TFT_RESET_PIN=27 -DUSE_DMA_TRANSFERS=OFF -DSPI_BUS_CLOCK_DIVISOR=4 -DDISPLAY_ROTATE_180_DEGREES=ON -DSTATISTICS=0 ..
because the build was complaining about the DMA module, I tried it without... and got a valid build:

Only to run into the following issue after running:
root@kali:~/fbcp-ili9341/build# ./fbcp-ili9341 ./fbcp-ili9341: error while loading shared libraries: libvchiq_arm.so: cannot open shared object file: No such file or directory
Any ideas where I get/find libvchiq_arm.so? How did this even build with the library missing?

5 years ago libcvhiq_arm.so is https://github.com/raspberrypi/firmware/blob/master/opt/vc/lib/libvchiq_arm.so , so perhaps it's in /opt/vc/lib/libbvhiq_arm.so?

5 years ago Sure enuf:
root@kali:~/fbcp-ili9341/build# ./fbcp-ili9341 ./fbcp-ili9341: error while loading shared libraries: libvchiq_arm.so: cannot open shared object file: No such file or directory root@kali:~/fbcp-ili9341/build# locate libvchiq_arm.so /opt/vc/lib/libvchiq_arm.so
Any ideas why the newly built binary can't see it?

5 years ago Ok, hope this helps some other poor rpi zero end user:
cd /lib/arm-linux-gnueabi ldd /opt/vc/lib/libvchiq_arm.so libvcos.so => not found locate libvcos.so ln -s /opt/vc/lib/libvcos.so . ln -s /opt/vc/lib/libvchiq_arm.so .
~/fbcp-ili9341/build/fbcp-ili9341
Now it works! ( might be slow due to lack of DMA but this is the 1st time I've got it to work on Kali so, pretty happy!)

5 years ago based on the manual here: https://www.waveshare.com/w/upload/6/6b/1.3inch_lcd_hat_user_manual_en.pdf
I'm changing the DC and reset pins as follows:
cmake -DST7789VW=ON -DGPIO_TFT_DATA_CONTROL=25 -DGPIO_TFT_RESET_PIN=27 -DUSE_DMA_TRANSFERS=OFF -DSPI_BUS_CLOCK_DIVISOR=4 -DDISPLAY_ROTATE_180_DEGREES=ON -DSTATISTICS=0 ..
and while it's very dark and very small, it actually works!

5 years ago Using the guide here:
https://www.raspberrypi-spy.co.uk/2014/04/how-to-change-the-command-line-font-size/
I cranked the font up quite a bit.. seems like I need it higher before my poor eyes can read it.. getting closer to usable.
TYVM for this awesome project!

5 years ago Used this resource: https://stackoverflow.com/questions/22891235/how-to-change-screen-resolution-of-raspberry-pi
and set the following in /boot/config.txt:
hdmi_force_hotplug = 1 hdmi_cvt = 240 240 60 1 0 0 0 hdmi_group = 2 hdmi_mode = 87 overscan_left=24 overscan_right=24 overscan_top=10 overscan_bottom=24 framebuffer_width=240 framebuffer_height=240 sdtv_mode=2 sdtv_aspect=2
and now I have a working console.

5 years ago When I rebuild from a scratch build of kali I also had to do:
apt-get install libraspberrypi-dev
To get around several errors and missing .h files.

3 years ago Closing out old issues, looks like this worked out eventually.
Building on an RPiZero w/ a waveshare 1.44 hat, using:
