Hi All,
I am working on custom i.MX6 quad hardware and using RT patches for almost latest stable kernel 4.9 and facing some weird system stall OR 'unhandled page fault - exceptions'.
I'm not sure about the unhandled page fault, but the stalls may be because of the SDMA driver.
See this patch in the Freescale/NXP community for kernel 4.1: https://github.com/Freescale/meta-freescale/blob/master/recipes-kernel/linux...
Thanks for the patch link. I will give it a try.
Talked to hardware manufacturer and they applied the patch. Still that SDMA is only used for NOR flash and only u-boot and its environment are stored in nor flash. So not sure if that is going to help in any case. So I would really like few more suggestions OR confirmations about ARM (cortex-A9 based imx6) (preemept)-RT support/patches are stable and can be used for final products. Thanks
Regards,
Eric
