Surfaceflinger SIGSEGV error.

kurkinalexandr — Wed, 18 Jul 2018 10:53:18 GMT

Hello.

Trying run Android 6 on Compulab cm-fx6 reference board.

But getting gpu surfaceflinger-gpu issue:

Fatal signal 11 (SIGSEGV), code 1, fault addr 0x0 in tid 207 (surfaceflinger)

This cause Android main services recursively being restarted and Android never can start.

Could you please give me some tips how to fix this issue, may be some extradebug needed for that.

Please see logcat output below.

Hi Fan

reason may be that wrong image used, as cm-fx6 may have i.MX6S and i.MX6Q processors

which require different images, one can check

CM-FX6 Freescale i.MX6 SW Resources - CompuLab Wiki

Alternatively one can try with nxp demo boards and Demo Images from

https://www.nxp.com/support/developer-resources/run-time-software/i.mx-developer-resources/i.mx-6series-i.mx-7series-software-and-development-tool-resources:IMX_SW

Best regards
