I have a problem about the uart of i.mx6ull working in interrupt mode.
Linux version: L4.1.15
Work flow: fast transmit or receive by interrupt.
a. when uart in work flow after some time, it will cause "kernel panic";
b. error log:
Unhandled fault : external abort on non-linefetch (0x1008) at 0xc88f4000
How can I fix it ?
