🔨[BSP][ESP32-C3] task issue #5941

supperthomas · 2022-05-13T14:26:01Z

task issue as follow

combine IDF and scons --targe=cmake build system
porting drv_gpio.c with cmake system
porting drv_uart.c with cmake system
porting drv_iic.c with cmake system
porting drv_spi.c with cmake system
porting drv_pwm.c with cmake system
add the menuconfig to rtconfig.h
fix IDF_PATH to local path

fix IDF_PATH to local path 目前可以考虑将IDF_PATH路径修改成pkgs里面的软件包作为编译的时候的IDF_PATH. 不过尝试多次之后，效果不是很理想，也比较麻烦。暂时不是很方便，后面再考虑，先把软件包提交上去。如果大伙有什么更好的办法，欢迎提供。目前需求是：如何编译的时候将IDF_PATH 指定到本地package/rtt_esp_idf-latest 文件夹下面，而且可以顺利编译通过。

单独打开BLE 这个app_main没有定义。

这个需要参考readme里面将esp-idf的nimble样例程序加入到编译中

这里用户自己操作起来问题会比较多，是不是可以提供一个step by step的步骤？

可否看下能不能默认状态下打开BLE宏，编译能通过？

好的，我看一下

请问现在的工具链可以确保编译成功么？

我在使用esp官方的gcc编译链产生编译错误：

scons: Reading SConscript files ...
CROSS_TOOL= gcc
EXEC_PATH= /home/lzx/.espressif/tools/riscv32-esp-elf/esp-2022r1-11.2.0/riscv32-esp-elf/bin

scons: *** [build/drivers/board.o] Error 1
scons: building terminated because of errors.

然后我在rtconfig.py文件中指定nosys.specs位置
DEVICE = ' -nostartfiles -march=rv32imc --specs=/usr/lib/riscv32-esp-elf/riscv32-esp-elf/nosys.specs '
之后又缺失cc1工具，当时使用脚本下载乐鑫的sdk被默认下载到/usr/lib里了，然后我又将cc1复制到了乐鑫默认sdk文件夹里 cp /usr/lib/riscv32-esp-elf/libexec/gcc/riscv32-esp-elf/11.2.0/cc1 /home/lzx/.espressif/tools/riscv32-esp-elf/esp-2022r1-11.2.0/riscv32-esp-elf/bin
然后又爆出标准库文件丢失的错误

根据网上的信息很可能是工具链设置出错，但是我是根据目前最新的教程移植的，请问楼主您最近移植rtt到esp32c3了么？可以编译通过么？

根据网上的信息很可能是工具链设置出错，但是我是根据目前最新的教程移植的，请问楼主您最近移植rtt到esp32c3了么？可以编译通过么？
下面是我的环境配置

谢谢，根据action已经配好了。应该是我之前下载esp-if工具链冲突了。后期我看看能不能把spi和pwm的驱动给补上
