Instructions for LPC interrupt binding under ft2000+

at present FT2000+ 64 Under the core, more LPC interrupt , To ensure that the interrupt is not lost and the interrupt response delay is within a certain range , You can bind interrupts , The following is an example of operation under Galaxy Unicorn .

1、 Modify system startup parameters , Set nuclear isolation

（ At least two cores need to be set , A running application , A binding break ）

Input in the terminal vi /etc/boot/grub/grub.cfg

Add isolcpus=10,11 ( Modify according to the actual application , If the application uses multiple cores , Just specify the verification number , You need to reserve an extra core for interrupts )

2、 Set interrupt binding and application binding

Add interrupt binding operation in the startup script , Can be put in /etc/rc.local in . The nuclei used are those isolated from above , As shown in the figure below

Bind interrupts to 11 nucleus

Used in applications 10 Nuclear operation , You can also set the binding operation in the program code , You don't have to use taskset
