Zero 2W 64bit port #261

zxfishhack · 2022-03-29T20:48:44Z

since mmap memory allocate by GPU trigger SIGBUS in 64bit system, I change DMA memory allocate to vcsm-cma.
I test only on rpi zero 2w, screen info: ili9341, resolution is 320x240

Will this work on 64bit pi4?

zxfishhack · 2022-03-31T17:51:18Z

I don't have a pi4, so I can't test it myself. I think this will work. Add -DAARCH=YES will enable 64bit build.

Solid work! Unfortunately it looks like there is a licensing conflict that will prevent from merging this code in :( Part of the code in this PR is licensed under GPL 2, which to my understanding is not compatible with the MIT license.

zxfishhack · 2022-04-13T12:28:22Z

rewrite CMA allocate code and remove code licensed under GPL 2

leandroalbero · 2022-04-13T16:07:28Z

Thanks for the port. I am not able to get it working on my Pi4 8GB, I get stuck with a 'Bus error' message.

bus error seen it don't enable 64bit port, 64bit port is disable by default.
add -DAARCH64=YES will enable new port. and you will see cmake output message "Enable AARCH64 build" and "Enabling Map Memory from CPU instead of GPU"

leandroalbero · 2022-04-13T16:28:56Z

That solved the 'Bus error', now I get an 'vc_dispmanx_display_open failed! Make sure to have hdmi_force_hotplug=1 setting in /boot/config.txt' even with hdmi_force_hotplug set to 1

zxfishhack · 2022-04-13T16:57:54Z

check GL Driver is 'Legacy', GL display driver will lead same error on my rpi zero 2w.(if DMA conflict, try change DMA channel as you mention in vc_dispmanx_display_open: command not found #262)
try increase gpu_mem to 64 or higher

leandroalbero · 2022-04-13T17:18:58Z

Tried points 1 (I can't find an option to change to legacy GL driver on Debian 11) and 2. But I can't get the screen to change state, all I get is a white screen. It is connected exactly as it was to my previously working Pi 3, here's the program output:

bus error seen it don't enable 64bit port, 64bit port is disable by default. add -DAARCH64=YES will enable new port. and you will see cmake output message "Enable AARCH64 build" and "Enabling Map Memory from CPU instead of GPU"!``

Hi!
This not resolves the bus error for me, I have already built it with that in mind:
sudo cmake -DWAVESHARE_ST7789VW_HAT=ON -DGPIO_TFT_DATA_CONTROL=22 -DGPIO_TFT_RESET_PIN=27 -DSPI_BUS_CLOCK_DIVISOR=6 -DSTATISTICS=number -DAARCH64=YES -DDMA_TX_CHANNEL=6 -DDMA_RX_CHANNEL=2 ..
I am on 64bit Bullseye (DietPi) (same config and cmdline.txt as yours), Rpi zero 2 w, it's almost a WaveShare 240x240 1.3inch IPS LCD Hat with ST7789VW controller.
(https://spotpear.com/index.php/index/product/detail/id/721.html).
The building gives me no error, other RX and TX channels are also not helping.
Do you have any other advice?
Thanks in advance

Got it working, with "-DUSE_DMA_TRANSFERS=OFF" switch, but now it is only showing white stripes with a lot of colorful noise in it. Any idea, how to fix this?

vineet131 · 2023-05-07T14:49:22Z

Hello,
Thank you very much for this PR! I just tested it today on my Pi 3B with 64 bit Raspi OS and Waveshare 1.3" LCD and I can confirm that it is working. Although I haven't tested out the refresh rate or in-depth details, I can just confirm that it is drawing well using the Waveshare provided source code.

Probably didn't mean to permanently change this to CS1 outside of the #ifdef DISPLAY_USES_CS1 below?

Works well for me.
If you do #100 (comment) but it has no effect, you can try sn-lab/MouseGoggles#23
