AM3358: AM335X linux kernel: touch DCAN RX interrupt,but Sometimes there a delay,about 18ms.
The Linux kernel version 3.0 does not have explicit support for the AM335X interrupt controller. However, it should still work with the interrupt controller on the AM335X SoC. The delay you are experiencing might be due to other factors such as interrupt handling in the kernel or the specific implementation of the interrupt controller driver. Upgrading to a newer version of the Linux kernel that provides better support for the AM335X interrupt controller might help resolve this issue.
