笔者有幸参加了平头哥RISCV开发者大赛,体验了一下基于玄铁C910内核的矽速开发板。
1、开发板介绍
LicheePi 4A 是基于 Lichee Module 4A 核心板的 高性能 RISC-V Linux 开发板。
- TH1520 为主控核心(4xC910@1.85G, RV64GCV,4TOPS@int8 NPU, 50GFLOP GPU)
- 板载最大 16GB 64bit LPDDR4X,128GB eMMC,
- 支持 HDMI+MIPI 双4K 显示输出,
- 支持 4K 摄像头接入,
- 支持双千兆网口(其中一个支持POE供电)
- 4 个 USB3.0 接口,
- 多种音频输入输出(由专用 C906 核心处理)。-
2、GCC工具链使用
GCC的工具链安装,参考Licheepi GCC工具链安装。
- 查看gcc的工具链版本
shell
root@lpi4a:~# gcc -v

Thread model: posix
Supported LTO compression algorithms: zlib zstd
gcc version 10.4.0 (Debian 10.4.0-8revyos2.4)
- 直接编译hello.c程序,提示需要设置xthreadc的版本,其实并不知道如何处理,经过查资料后发现,需要指明架构和二进制接口版本
shell
gcc hello.c
Assembler messages:
Error: x ISA extension `xtheadc' must be set with the versions
- 然后根据提示指明了架构,发现对应的头文件找不到,怀疑工具链没安装对,重新安装了,但是依然没什么用,之后又重启了,还是不行,看来还得继续找问题。
shell
gcc hello.c -march=rv64imc
In file included from /usr/include/features.h:513,
from /usr/include/riscv64-linux-gnu/bits/libc-header-start.h:33,
from /usr/include/stdio.h:27,
from hello.c:1:
/usr/include/riscv64-linux-gnu/gnu/stubs.h:14:11: fatal error: gnu/stubs-lp64.h: No such file or directory
14 | # include <gnu/stubs-lp64.h>
- 然后就看一下该文件的内容,以及去该目录下面搜索了有哪些文件
shell
root@lpi4a:~# ls /usr/include/riscv64-linux-gnu/gnu/stubs.h
/usr/include/riscv64-linux-gnu/gnu/stubs.h
root@lpi4a:~# cat /usr/include/riscv64-linux-gnu/gnu/stubs.h
/* This file is automatically generated.

#include <bits/wordsize.h>
#if __WORDSIZE == 32 && defined __riscv_float_abi_soft
# include <gnu/stubs-ilp32.h>
#endif
#if __WORDSIZE == 32 && defined __riscv_float_abi_double
# include <gnu/stubs-ilp32d.h>
#endif
#if __WORDSIZE == 64 && defined __riscv_float_abi_soft
# include <gnu/stubs-lp64.h>
#endif
#if __WORDSIZE == 64 && defined __riscv_float_abi_double
# include <gnu/stubs-lp64d.h>
#endif
shell
ls /usr/include/riscv64-linux-gnu/gnu/
lib-names-lp64d.h lib-names.h libc-version.h stubs-lp64d.h stubs.h
- 看到这里就突然知道,需要指明对应的版本,不然相应的头文件找不到,果然和常规的GCC工具链使用还是有区别,增加了相应的abl版本后,发现march也需要版本,
shell
gcc hello.c -march=rv64imc -mabi=lp64d
cc1: error: requested ABI requires '-march' to subsume the 'D' extension
- 在架构方面增加了d,发现还是不对,提示第一个指令集是e/i/g,还得修改
shell
gcc hello.c -march=rv64dimc -mabi=lp64d
gcc: error: '-march=rv64dimc': first ISA subset must be 'e', 'i' or 'g'
- 然后修改了abl的,改成了e,发现abl的版本里面没有这个,必须是lp64d,所以又得改回去
shell
gcc hello.c -march=rv64imc -mabi=lp64e
gcc: error: unrecognized argument in option '-mabi=lp64e'
gcc: note: valid arguments to '-mabi=' are: ilp32 ilp32d ilp32e ilp32f lp64 lp64d lp64dv lp64f lp64v; did you mean 'lp64'?
- 最后在march指令集的后面增加d,可以了,终于gcc工具链可以正常使用了。
shell
root@lpi4a:~# gcc hello.c -march=rv64imafd -mabi=lp64d
root@lpi4a:~#
- readelf工具可以查看其out文件信息,RISC-V的machine的64位机器版本
shell

注意事项:
1、安装是需要后面添加参数 --fix-missing(根据提示)
2、安装时系统可能会卡死,这时候安装包可能损坏,需要修复这个问题,dpkg --configure -a,
3、继续安装的时候,又会发现没有依赖或者依赖关系不对,需要apt --fix-broken install
