Work flow: fast transmit or receive by interrupt.
2>result

b. error log:
Unhandled fault : external abort on non-linefetch (0x1008) at 0xc88f4000
How can I fix it ?

Hi Jimmy
Linux L4.1.15 is very old version not more supported, may be recommended
to try latest Linux 4.14.98_2.3.0 Documentation or Linux 4.19.35_1.1.0 Documentation
Best regards
igor

Hi Igor,
Thanks for your reply.
But, we have developed in L4.1.15, it may be a huge work to update the version.
If you have another suggestion, we will try.
Thanks again.
