"Milk-V Duo is an MPU based on the Altek CV1800B chip, capable of running operating systems based on both LINUX and RTOS. The Altek CV1800B chip features the XuanTie C906 core, known for its powerful processing capabilities. Hence, we attempted cross-compiling the OpenCV image processing library for use with Milk-V Duo. XuanTie’s website (https://xuantie.t-head.cn/community/download?id=4112956065753141248) offers an optimized custom version of OpenCV, believed to maximize the chip’s performance. This version holds great promise.
The only only xthread .so in the /lib directory is:
lrwxrwxrwx 1 dhcpcd dhcpcd 37 Oct 21 2023 ld-musl-riscv64v0p7_xthead.so.1 → …/usr/lib64v0p7_xthead/lp64d/libc.so
So, I created the following simlink:
[root@milkv-duo]/lib# ls -l /lib/ld-musl-riscv64xthead.so.1
lrwxrwxrwx 1 root root 35 Jan 1 00:44 /lib/ld-musl-riscv64xthead.so.1 → /usr/lib64v0p7_xthead/lp64d/libc.so
