After R3 vision, the is no support for hardware interrupt for TX2?
its true for this

Hi, what do you mean “R3”? Hardware interrupt is supported on TX2.

thanks a lot, we use Jatpack 4.2.2 vision,how to reflash Karnel interrupt?
also we found some GPIO issue,
Pin15 and Pin22 dont have interrupt capability after we use terminal operation and export.
dont have any signal out。

Do you mean pin GPIO_EXP_16 and pin GPIO_EXP_17 of connector J21?

its pin40 can use as Audio I2S Dout

Hi denvend,

What was your method that works on rel-28?
