Hello,

 

We have been developing a system software for Freescale i.MX6Q using i.MX6Q Sabre Lite.

We encountered imprecise external abort (0x1c06) suddenly, we think it seemed the problem in regards to coherency between L2 Cache and CPU Cores.

 

According to Table B3-23 in the DDI0406C, FS was 11010,  it means implementation defined. .

 

Could you please advise us on the issue ?  We would like to know why the abort was happened, and tell us a workaround if you have already known the issue.

 

Thank you in advance,

-Yoshinori Kimura
