riscv64的示例有问题,arm的Linux快速上手部分没有提供Linux运行脚本

你好,我按照快速上手的linux版介绍,尝试构建riscv64版本的用户程序,执行如下命令:

python get_toolchain.py riscv64
source smart-env.sh riscv64

但是出现如下错误:

通过echo $PATH命令,可以看到我的路径是正常的:

不清楚为什么会这样报错?

如果不加sudo前缀,只使用scons,会产生如下错误:
图片
好像是riscv工具链有点问题?

另外,快速上手中还包含了arm的示例,这部分可以正常构建出用户态应用程序。
但是userapps\prebuilt\qemu-vexpress-a9目录下没有Linux平台的运行脚本。尽管我可以参考.bat文件自己写一个脚本,但还是希望能看到官方的示例和源码一致 :)

谢谢

error: invalid task: smart-rootfs

后来发现是env.sh里面路径的问题

script_dir="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"

应当改成,测试正常工作

script_dir=$(cd `dirname $0`; pwd)

关于移植到loongarch64的问题

我看到文件里使用musl的交叉工具链编译源码,比如riscv64-linux-musleabi-...
我希望把RT-Thread内核以及用户程序移植到loongarch架构上,但目前loongarch架构的musl交叉工具链似乎还没有。
但是有loongarch64-linux-gnu-gcc等工具链,请问能否用这种工具链替代呢?

关于工具链统一路径的问题

get_toolchain.py 下载的工具链的路径默认在此项目的相对路径下,这样就造成我这样的社区开发者开发用户app时,每次都要切换工具链路径,代码交给别人编译时也要改工具路径,这十分的麻烦。如果统一了工具链路径,至少开发者拿到一份新的代码可以做到开箱即用了

methods to create the prebuilt kernel

Hi,

May I ask how to built the prebuilt kernel such as prebuilt/qemu-virt64-riscv/rtthread.bin?

I download the v5.0.1 release of RT-Thread and built a bsp/qemu-virt64-riscv/rtthread.bin successfuly, but when I replaced the prebuilt kernel with mine and runs the demo, it complains that: [E/DBG] virtio-blk0 mount failed.

I guess the ext4 file system driver is absent from my kernel, so I turned on CONFIG_PKG_USING_LWEXT4 and rebuild, but got the following error:

smart-env.sh配置工具链路径错误

ubuntu系统,在userapps\tools目录下运行get_toolchain.py的脚本

:~/userapps/tools$ python3 get_toolchain.py riscv64

之后

:~/userapps/tools$ cd ..
:~/userapps$ ./smart-env.sh riscv64
Arch      => riscv64
CC        => gcc
PREFIX    => riscv64-unknown-linux-musl-
EXEC_PATH => /home/auser/userapps/tools/gnu_gcc/riscv64-linux-musleabi_for_x86_64-pc-linux-gnu/bin

这里就不对吧?
之后
使用set命令检查RTT_EXEC_PATH是否设置成功 用什么具体命令呢?

再编译,总是如下错误

:~/userapps$ scons
scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...

请问该如何处理?
