LINUX SC16IS752 DRIVER



Ok that did the trick my script is now executing even when I'm running the send loop on both lines, but I'm now facing another big problem: My pi sometimes freezes completely so that I have to unplug and repower it again. Looks linux sc16is752 it sometimes get stuck in an endless loop maybe because the interrupt isn't cleared completely. Which Pi do you have? If it's a Pi 2 or a Pi 3 then there should be 3 cores available while one of them is stuck in an interrupt loop if indeed that is what is happening. Also, stuck interrupts should eventually get disabled. linux sc16is752

linux sc16is752 Transmission and the reception done with interrupt technique 5. I hope that helps. Please start a topic on the Device Tree forum linux sc16is752 your problem - please include full details of what you have tried, and post or link to your overlay file s. There is some config where I can tell that the sc16isspi1 overlay will be used on i2c? But we want to use them in RS mode also and we can't get that working. See errno.

And this error goes away if linux sc16is752 comment out : rsconf. But the correct registers never show up, so the enabling of the rs mode and the polarity register.

New issue. The easiest option would be to ask for the module to be added to the standard configurations - create an issue here. Since linux sc16is752 is only a 24KB module and the overlay that uses it is already in the build, you have a good chance of success. JackD May 16,am 3.

Thanks for the reply asyal. Thank you all for your help. I'm going to assume you are using I2C address 0x51 see Table 32 in the manual linux sc16is752 the configuration required - just divide the address shown by 2, so 0xa2 becomes 0x Re: Configure sc16is7xx chip on compute module Tue Dec 22, am Hi Jorge, Your question about this chip came up at the same time I was working on the same problem. Being very new to this sort of stuff when I began, it took a long time to get right, so hopefully this will save you some time on your quest to get this chip working.

I was just hoping it was a case of installing a driver. The issue is caused by the fact that the SC16IS has an Enhanced Feature Register which is aliased at the same address as the Interrupt Identification Register; accessing it requires that a magic value is written to the Line Configuration Register. If an interrupt is raised while the EFR is mapped in then the interrupt handler won't be able to access the IIR, leading to the error messages you've seen. My preferred solution linux sc16is752 to explicitly mask the interrupt from the device for the critical period while the EFR register is swapped in, but I don't have the means to test the change.
