I am poritng android 5.0 to our hardware. The boot is OK and we can boot into Launcher.
Problem we have is when we execute some native program in console, kernel
log show "undefined instruction" like:
# /system/bin/wm
[ 953.473988] app_process (1557): undefined instruction: pc=b6ab9848
[ 953.480384] Code: e320f000 e320f000 f26001f0 e12fff1e (ec510f1e)
usage: wm [subcommand] [options]
wm size [reset|WxH]
wm density [reset|DENSITY]
wm overscan [reset|LEFT,TOP,RIGHT,BOTTOM]
After a short search, we find the code is in external/openssl/armv4cpuid.S
#include "arm_arch.h"
.text .code 32
.align 5
.global _armv7_neon_probe
.type _armv7_neon_probe,%function
_armv7_neon_probe:
.byte 0xf0,0x01,0x60,0xf2 @ vorr q8,q8,q8
.byte 0x1e,0xff,0x2f,0xe1 @ bx lr
.size _armv7_neon_probe,.-_armv7_neon_probe
Our CPU is ARMv7 , this institution should be supported. Even we change
this function to Android 4.4 version still get similar message.
Any one have the same experience?
