JK 10:05 AM MitySOM-5CSX Altera Cyclone V Software Development: RE: Using PREEMPT_RT on MitySOM 5CSX Dev Board

Hi Dan,
The network stability problem has disappeared after removing the skews. Thanks for the suggestion!
I'll soon proceed with additional defconfig/dts modifications, starting with the suggestions above.
Thanks,

Hi Jared,
Looking at the sockit dts(https://github.com/altera-opensource/linux-socfpga/blob/socfpga-4.1.22-ltsi-rt/arch/arm/boot/dts/socfpga_cyclone5_sockit.dts) I see they are setting skews for the data clocks for the RGMII phy. We d... Daniel Vincelette

Hello Dan,
I've been performing more testing on the Altera 4.1.22 LTSI RT branch.
Physical setup: MitySOM 5CSX H6 HYA dev kit connected to network via Ethernet (J500).
Altera 4.1.22 LTSI RT does indeed get an IP address, but the... Jared Kirschner

Hello Jared,
That sounds like a perfect approach. For building the file system we do use yocto, which as you saw is pointed to use the 3.16 kernel. Now depending on how manual you want to do this I can suggest a few options.

Good question, I'm not sure if there are any files on there that specify which version it is. But if nobody has updated it since you bought it then it will be running the older MDK filesystem. Jonathan Cormier

Looks like you are using the older toolchain which apparently doesn't have the rpl_* support. This post gives some possible solutions.

Jonathan,
I used the tarball instead of the git, I share you my log, it is different than yours, it is attached.
I can see some Errors. After this Should I be able to compile in Eclipse using the library ?
Thanks,
