linux SC16IS driver,Receive Line Status error | NXP Community
I will set up a VM with Ubuntu tonight and cross-compile. Loaded overlay ‘i2c-rtc’ I started compiling locally but a quick search in the forum tells me it will take 5hs or more. It also cleans the flag that generated the interrupt. Transmission and the reception done with interrupt technique.

Thanks to a major collaborator for this document David Diaz Marin. Therefore I have more then one Sc16si752 and I don’t want to compile each of them. Yes of course I can follow the instructions on the side, but do I still get updates after recompiling the kernel? Initialization of the bridge to perform the communication. Priorities won’t solve your problem completely anyway, because sc16ie752 always a chance for another unrelated IRQ to arise between your IRQ and the process.
Thanks for your assistance!
But queued work is performed within 25ms after interrupt occurs. Driver ‘spi-bcm’ is already registered, aborting The example shows the device functionality by creating a simple echo transmission, where you are able to read what you just write into the device.
Board index All times are UTC.
This is the main, that should be executed to perform the echo function. Now I can see spidev0. What is the correct solution in this situation and how to reduce 25ms latency in Linux Kernel? I will play around with this and let you know the results. Renaming the clock nodes and the overlays themselves to be more logicalI ended up with these: In the example channel 0 is used. So, it seems that the DTB file name matters.

In the interrupt service routine the program reads the interrupt identification register, and it’s ready to sc16s752 a different task for each interrupt, for now it simply enables the data ready flag when the interrupt was generated by the RHR.
