Hello, I just wonder if anyone here work with the highly interrupted system before ? I am new to Jetson platforms and I think there are different ways for interrupt handling on other platforms, but on this platform all interrupts go to core 0. This creates problems in systems that generate interrupt…

What carrier board are you using? Is this an actual dev kit, or does it use a third party carrier board? Note that the signal used for PCIe is quite fast and needs to be close to perfect. The signal quality for this is a combination of devices, which includes the device end point and any PCIe bridg…
