根据需求，我们需要以OpenWRT作为主系统，同时使用NPU功能。在AIO-3568J开发板上烧写FireFly提供的官方OpenWRT固件，再将RK官方的rknn_ssd_demo_Linux推送到到开发板中，执行rknn_ssd_demo，提示 /bin/ash: ./rknn_ssd_demo: not found。 在 /lib目录建立软链接 ld-linux-aarch64.so.1 → libc.so，并将RK官方Linux SDK的libstdc++.so.6.0.28（FireFly 提供的Ubuntu镜像中的libstdc++.so.6.0.25、编译链中的libstdc++.so.6.0.22）推送到/lib目录下，建立相应的软链接，执行rknn_ssd_demo，则提示以下错误：
Error relocating lib/librknnrt.so: __strdup: symbol not found
Error relocating lib/librknnrt.so: __log2_finite: symbol not found
Error relocating lib/librknnrt.so: __pow_finite: symbol not found
Error relocating lib/librknnrt.so: __log2f_finite: symbol not found
Error relocating lib/librknnrt.so: __exp_finite: symbol not found
Error relocating lib/librknnrt.so: __powf_finite: symbol not found

Error relocating /lib/libstdc++.so.6: __cxa_thread_atexit_impl: symbol not found
Error relocating /lib/libstdc++.so.6: __strftime_l: symbol not found
看起像是系统库函数的问题，请问是否有同样的需求？是否遇到过这种问题？ 谢谢

补充一下，通过readelf查看RK官方Linux SDK包中编译出的libm-2.29.so中包括__pow_finite、__exp_finite等函数原型，但将此库文件推送到板端后，建立相应的软链接，同样会报以上错误。
