I don’t see problem with WP76 R13 with attached binary:
valgrind.rar (3.3 MB)
- mkdir /tmp/valgrind
- mkdir /tmp/tmp_lib;mkdir /tmp/tmp_lib_wr;
- cp -rf /lib /tmp/tmp_lib
- mount -t overlay overlay /lib -o lowerdir=/lib,upperdir=/tmp/tmp_lib,workdir=/tmp/tmp_lib_wr;
- Use WINSCP to transfer all the binary to /tmp/valgrind
- Use WINSCP to transfer ld-linux.so.3 to /lib ( cannot copy directly from /tmp/valgrind to /lib)
chmod -R 777 /tmp/valgrind
