xboot 说：D1芯片的SVD寄存器文件，有什么好用的工具去看这玩意吗？
keil有所谓的svd文件，就是看寄存器的，但是keil肯定不可能支持riscv啊。
SVD不是ARM搞出来的寄存器布局描述文件吗，应该一般适用于ARM处理器吧
The compiler you showed is provided by Ubuntu and is NOT the one you can considered as "OFFICIALLY" supported by Allwinner.
Correct compiler version is something like this: (I'm using a D1 chip based on RISC-V, so your version info is guaranteed differ from mine)

Use the compiler which your image builder generated (in $BUILDROOT/output/host/opt/ext-toolchain/bin/$TUPLE-gcc) should just work, as u were using the system provided cross-compiler which provided a higher version of glibc (2.33) not forward-compatible with the version configured in image builder.
Also, compiling with the '-static' flag should attach all the library used to your program, preventing any possible missing / version miss matched / etc. library problem at all, consider it when you are not familiar with target system environment.
