Do you have the possibility to measure with an oscilloscope? I messed with the adapter board and lost the display, so this might be only a hardware problem. Then you use gpicview to display some testpictures fullscreen. Still, after compiling and testing, it doesn’t improve much. Perhaps a PWM channel could be made to gate the sample clock so that only data from the desired horizontal zone are captured, greatly reducing the required buffer size. Any guidance is welcome!

Hello Max, thank you for your answer.

It is important that you create new questions related to the Apalis iMX8QM sample in this confidential space. Then you use gpicview to display some testpictures fullscreen. If you are up for a bit of circuit wrangling, check out the [[http: Here’s my major update: Hello My mistake, i instinctively assumed it was a frequency.

Analogue Camera Module (ACM) – Main Features, Datasheets

I mx9526 a configuration file with a screen and let him auto-add the device. I assume it works as intended. If i put one, goes back to what it was before.

Actually, if i put the clock just as my display’s datasheet indicates, it flicks even more. What do you mean by flickering?

At this point my nemesis is Gstreamer. If the DMA cannot complete within 7 cpu-clocks, the gating scheme linuxx still be used to reduce a high-speed capture buffer to a few more TTL gates, counter chips, and a small RAM. As of Fusion, you are right, it’s the only one with inverted clock.

No space left on device. Please use the answer feature only if you are answering the question, otherwise, please use the Add Comment feature. Following the guide provided hereby modifying the vidargs u-boot variable to the closest i could find – FusionF I got some picture for you. I’d be more interested if the same ‘flickering’ you see with X is also visible when in console mode. After some research i found the file: Sorry for all the inconvenience, i’ll make mqx9526 when I recover from this and any software related solutions assuming it is not simply a hardware problem are welcome: I amx9526 your cat commands I’m aware that these commands end with an error once all of the framebuffer has been written with ‘black’, ‘white’ or random data.

I think DMA is overkill, the guy wants 8 pixels every 5 frames mswhen spaced equally that is maxx9526 sample frequency of 40Hz.

I forgot to add some details, i changed the PWM backlight to 10kHz from the default kHz, it didnt change much. The basic idea is to run the sample-rate clock to a Counter-Timer external input pin. Interface Display port in Ixora. Perhaps a PWM channel could be made to gate the sample clock so that only data from the desired horizontal zone are captured, greatly reducing the required buffer size.

I know this has been asked before http: You would have to figure out how to pick off the 8 pixels of interest from that firehose of data It happens the same thing. I tried creating a separate display there, didn’t go too well, hence I am modifying the FusionF07 to my needs. pinux

I’m aware that these commands end with an error once all of the framebuffer ma9x526 been written with ‘black’, ‘white’ or random data. Note that PWM in the device tree takes a periode, not a frequency. These tests were performed in LXDE:. Help Legal Privacy Policy Contact.
