I am trying to increase the buffer size of the SPI driver, to be greater than `4096`. ``` [root@luckfox ]# cat /sys/module/spidev/parameters/bufsiz 4096 ``` I've recompiled with the below change. But it didn't do what I wanted. ``` --- a/sysdrv/source/kernel/arch/arm/boot/dts/rv1103g-luckfox-pico.dt...

Device: Luckfox Pico Pro Max PWM Device: PWM5_M1, Pin 72 I am trying to get PWM to work on my device, but even though I am confident I have followed instructions correctly, I am not getting any PWM output. I am able to export the PWM5 pin, which then gives me the additional PWM properties: ``` [root...

Can you please provide me `.config` file and highlight the relevant sections? ``` sysdrv/source/buildroot/buildroot-2023.02.6/.config ``` I can compile buildroot images for SPI flash which work fine (camera works), but if I do the same exact process (as far as I can tell) using a SD card target, the...

In the end, I DONT GOT IT.

The above configuration, does work using SPI flash, but in MicroSD mode, it does not work.

I am quite stumped at this point.

In the end, I got it. It seems like LIBCAMERA_APPS was the missing one. ``` BR2_PACKAGE_LIBCAMERA_ARCH_SUPPORTS=y BR2_PACKAGE_LIBCAMERA=y BR2_PACKAGE_LIBCAMERA_V4L2=y BR2_PACKAGE_LIBCAMERA_HAS_PIPELINE=y # BR2_PACKAGE_LIBCAMERA_PIPELINE_RASPBERRYPI is not set BR2_PACKAGE_LIBCAMERA_PIPELINE_RKISP1=y ...

I just wanted to add some additional info here: Here is my `/etc/luckfox.cfg` file: ``` SPI0_M0_CS_ENABLE=1 SPI0_M0_MODE=1 SPI0_M0_STATUS=1 SPI0_M0_MISO_ENABLE=0 SPI0_M0_SPEED=40000000 CSI_ENABLE=1 UART4_M1_STATUS=0 PWM11_M1_STATUS=0 PWM10_M1_STATUS=0 PWM9_M1_STATUS=0 PWM8_M1_STATUS=0 PWM0_M1_STATUS...

I have successfully flashed my Luckfox Pico Pro Max with the stock OS images, which are available on Google Drive. With this image installed, I am able to communicate with the camera. I see files located in /userdata/ and /dev/video0 is populated. However, when I use the SDK to do my own buildroot c...

Also, for clarification, there is a SocToolKit for Linux at https://github.com/LuckfoxTECH/luckfox-pico/tree/main/tools/linux/SocToolKit As SocToolKit didn't work for me, I did this blkenvflash script which allows to write to the SD card direct on the Linux Host: https://gist.github.com/Spiritdude/...

I appreciate your message Crocodile. I will take your advise and hopefully I figure it out before somebody else does. But the bounty is ON, if someone can provide me with a fully working implementation with instructions, I will pay out. If they can save me 5 hours of headaches it will be worth it. I...

Development bounty: $250 payable in Bitcoin I really need some help with something, which could have a large impact,and I have wasted too much time trying to figure it out already. Goal: Using the buildroot image and Python, I want to be able to take photos using the CSI camera, and read them into a...
