vscode的插件platformio，目录结构该如何规划？

去年买了sipeed的longan开发板，官方提供的badapple例程是基于platformio的工程。到时可以通过串口下载程序。

想试试rt-thread-nano，结果下载下来后，不知道该如何添加到platfromio工程里。
新建的platfromio工程有lib,src,include三个文件夹，还有个.ini配置文件。
而下载的rt-tread-nano文件夹下，是有bsp,components,include,libcpu,src这几个目录。

尝试将rtt源码全放进lib目录，然后将其中的bsp里的关于gd32的文件夹移出放置到工程根目录下的src目录下。
结果编译时报错，main.c里的两个头文件都找不到，手动输入路径后，又有其他的.c文件报错找不到.h。
完全不知道目录结构该如何设置。

Re: vscode的插件platformio，目录结构该如何规划？

比如 #include <rtconfig.h> ，我不名为这里为什么用的是<>而不是""，我网上搜到的信息是，#include< > 引用的是编译器的类库路径里面的头文件。
而这个rtconfig.h显然不是放在编译器的类库路径下吧。

Re: vscode的插件platformio，目录结构该如何规划？

将git上rt-thread-nano工程文件里的bsp里的gd32xxx文件夹，复制到platformio的src目录下，然后将rt-thread-nano工程里除bsp外的其他文件，都复制到platformio工程目录下新建的rt-thread-nano目录下。
然后的.ini文件里设定build_flag = -Ixxx，xxx指的是编译时需要用到的头文件目录。
这样，一开始的几个找不到头文件的报错，没有了。但是最后还是编译失败了，找不到"entry" "rt_interrupt_enter" "rt_tick_increase" "rt_interrupt_leave"。

Re: vscode的插件platformio，目录结构该如何规划？

经群里朋友指点，将rt-thread-nao从platformio工程目录移到了lib目录下，编译又进了一步，现在的报错是貌似找不到rt_hw_interrupt_enable()这个函数定义。

...略去一部分报错...

我搜到了整个目录，只在两个地方找到了相关，分别是rthw.h和context_gcc.S。但是rthw.h里是声明，没有在.c文件里实现定义。
难道说context_gcc.S里的这几句汇编就是函数定义？

/*
 * rt_base_t rt_hw_interrupt_disable(void);
 */
    .globl rt_hw_interrupt_disable
rt_hw_interrupt_disable:
    csrrci a0, mstatus, 8
    ret

/*
 * void rt_hw_interrupt_enable(rt_base_t level);
 */
    .globl rt_hw_interrupt_enable
rt_hw_interrupt_enable:
    csrw mstatus, a0
    ret

Re: vscode的插件platformio，目录结构该如何规划？

想试试rt-thread-nano，这个好像不能用scons来生成工程。

在context_gcc.S里有rt_hw_interrupt_enable相关定义。
我将context_gcc.S从lib的下级目录移到src的下级目录，和start.S和entry.S两个汇编放到一块。编译不报那个错误了。

但又找不到rt_hw_context_swith_interrupt和rt_hw_statck_init这两个函数定义，但我搜了下，在context_gcc.S和cpuport.c两个文件里，都有相关函数定义。

又查了下，这个函数定义是有条件的：RT_USING_SMP

Re: vscode的插件platformio，目录结构该如何规划？

查了下这个SMP，说是对称多核用的...可我这是个单核单片机啊...

随便找了个地方使能了RT_USING_SMP。
再次编译还有个函数未定义的错误，查了下这个函数在libcpu/risc-v/comon/cpuport.c里，将这个.c文件移动到src目录下，编译通过了。

感觉像是src目录下的.c和.S文件都会被编译。
而lib目录下的，则是有条件的编译，但是不清楚是什么条件。

Re: vscode的插件platformio，目录结构该如何规划？

main函数里实现了点灯功能：

#include "gd32vf103v_eval.h"
#include <rtthread.h>

int main(void)
{
    gd_eval_led_init(LED1);

    while (1)
    {
        gd_eval_led_on(LED1);
        rt_thread_mdelay(500);
        gd_eval_led_off(LED1);
        rt_thread_mdelay(500);
    }
}

我修改了LED1的定义，改成longan板上三色灯中的一个PA1:

#define LEDn                             4U

#define LED1_PIN                         GPIO_PIN_1
#define LED1_GPIO_PORT                   GPIOA
#define LED1_GPIO_CLK                    RCU_GPIOA

编译后下载到板子上，结果，等没反应...

Re: vscode的插件platformio，目录结构该如何规划？

aozima 说：

灯没反应是否是心跳没起来？

我这里应该不应该定义RT_USING_SMP这个宏定义呢？

SMP（对称多核处理器）,这是我网上搜到的，但我这里肯定是个单核的单片机啊。

Re: vscode的插件platformio，目录结构该如何规划？

gd32vf103v_eval.c有个delay_1ms()函数，原来设参数1000，打算延时1秒让灯亮灭。
昨天观察到的现象是灯常亮，实际上是灯闪频率极高。现在调成1000000000，然后又用个for循环将这个延时函数调用100次，现在大概是1秒-2秒的周期闪灯。

--------------------------------

修改了下start.S，将call entry改回call main，这样应该就不是rtt了吧，再次编译下载，灯可以按预设的频率闪烁。

---------------------------------

貌似是delay_1ms()函数的参数不起作用了，无论设成多少，该函数都实现了固定时间的延迟，我上一步实现的灯闪，实际上是拷外层for循环调用delay_1ms实现的。

好奇为何这个函数的参数失效了？

/*!
    \brief      delay a time in milliseconds
    \param[in]  count: count in milliseconds
    \param[out] none
    \retval     none
*/
void delay_1ms(uint32_t count)
{
	uint64_t start_mtime, delta_mtime;

	// Don't start measuruing until we see an mtime tick
	uint64_t tmp = get_timer_value();
	do {
	start_mtime = get_timer_value();
	} while (start_mtime == tmp);

	do {
	delta_mtime = get_timer_value() - start_mtime;
	}while(delta_mtime <(SystemCoreClock/4000.0 *count ));
}

---------------------------------------

直接调用rt_thread_mdelay()函数，结果灯连亮都不亮，感觉应该是卡到这里了。

Re: vscode的插件platformio，目录结构该如何规划？

换下头脑。
之前移植是用的串口下载，每次都要按键boot重启。
买这个longan-nano时也买了个sipeed的usb转jtag/ttl。之前试过配置platformio的.ini文件，下载协议设置为jlink。
可下载总是失败：

jtag
Warn : Transport "jtag" was already selected
jtag
adapter speed: 1000 kHz

Error: No J-Link device found.

今天又试了试，发现还可以选sipeed-rv-debugger，结果下载后也提示失败，在github上看到也有人遇到这个问题。

Re: vscode的插件platformio，目录结构该如何规划？

https://github.com/sipeed/platform-gd32v/issues/12
看这个问题说，下载芯来的最新版的openocd，就可以下载了。
可我下载后解压得到了个文件夹，不知道该怎么用，里面的bin目录下倒是有个可执行文件openocd。
我在platformio的.ini文件里，将debug_tool修改为custom，debug_server改为刚下的openocd地址，结果执行下载还是包一样的错误。

Re: vscode的插件platformio，目录结构该如何规划？

aozima 说：

libraries\n22\env_Eclipse\init.c 里面有个 init 函数 ，你在 board.c 中手动调用一下看看。
感觉是心跳没起来

我用的是bsp里的gd32vf103_eval那个工程文件，init.c的路径是libraries/RISCV/env_Eclipse,里面有个_init()函数。我在board.c里的rt_hw_board_init()里开始的地方手动调用了_init()函数，结果现象依旧。
并且，rt_hw_board_init()里有个risc_clock_init()函数，里面实现的，基本和_init()函数一致。

Re: vscode的插件platformio，目录结构该如何规划？

把工程删了。又重新走了一遍：
1将rtthread-nano源码放到lib目录下；
2将rtthread-nano源码下的bsp下的gd32vf103-blink目录下的文件，全部放到src目录下；
3将rtthread-nano源码里的libcpu目录下的，arm目录删了，risc目录下，除bomblebee和common两个目录外的其他文件夹删了。其实也可以不删，估计不影响；
4然后将bomblebee和common目录下的cpuport.c,context_gcc.S,entry.S放到platformio工程目录下的src目录下或src下的任意目录下。如果放在原lib目录的下级目录下，总是编译不了，会提示找不到其中的各种函数定义。
5.ini文件里设置编译时报错找不到的各种头文件路径，我这里是这样的：
build_flags =
    -Isrc/drivers
    -Isrc
    -Ilib/rt-thread-nano/include
    -Ilib/rt-thread-nano/src
    -Ilib/rt-thread-nano/libcpu/risc-v/common

上传下自己的工程，现在开机启动后，不知为何打印了两遍rtt图标。

剩下的问题还有用jtag/sipeed-rv-debugger不能下载。在github的longan仓库上看到有人提到过这个问题。说是用芯来的最新的openocd可以下载。但是我不知道如何将下载下来的Openocd加入到platformio工程中去。

Re: vscode的插件platformio，目录结构该如何规划？

发现运行rtt程序后，串口显示两次版本信息。经群里朋友指点，应该是复位不稳定的原因。longan开发板复位引脚是个10k电阻和0.1uF电容实现的阻容复位，可能电容太小了。
在rtthread_startup()函数前加了个延时，暂时躲过了这一现象。

又发现，其实是可以用sipeed-rv-debugger下载的，是有报错，但是重启后发现程序已下载进去可以运行。
这是报错信息：

.ini里upload_protocol选的是sipeed-rv-debugger，选jlink不行。但sipeed-rv-debugger写的是usb转jtag。
jlink难道用的不是jtag协议吗？

------------------------------------------------

用sipeed-rv-debugger也可以调试。
vscode左边栏里有个“运行”图标是个向右的三角加上一个虫子，打开这个侧边栏后，最上方有个“开始调试”框，选pio debug，就可以了。
感觉这样的话，可以替代mdk了。

Re: vscode的插件platformio，目录结构该如何规划？

发现msh功能打不开。工程目录里已包含msh相关文件，rtconfig.h里也使能了RTE_USING_FINSH。main函数的while循环里也有rt_msdelay()。但是打开串口后，只看到打印的rtt图标，以及main线程里定时打印的一句字符串。

难道c8t6的20k ram太小了？

Re: vscode的插件platformio，目录结构该如何规划？

shell.c里有int finsh_system_init(void)函数，会创建finsh线程，而这个函数是通过INIT_APP_EXPORT(finsh_system_init)来实现自动启动的。

我在int finsh_system_init(void)函数里加断点，结果运行仿真后，发现无法在这里停下。

--------------------------------------------

断点是不是只能加在main函数以后呢？

------------------------------------------

在main函数前可以加断点，刚才是操作不对。

--------------------------------------------------

又考虑是不是component/finsh文件夹在platformio的lib目录下，.c文件没有被编译进去？
明天再试试将文件移到src目录下试试。

Re: vscode的插件platformio，目录结构该如何规划？

将所有rtthread文件夹都放到了platformio的src目录下，结果仍然是无法使能msh。

Re: vscode的插件platformio，目录结构该如何规划？

尝试编译Lvgl，报错：

----------------------------------------

经群里朋友指点，.bss已经34k多了。
可我看Lvgl介绍说16k ram需求就够了啊。

------------------------------------------------

我试着改了下lv_conf.h的分辨率，改大改小，最后编译报错时.bss占用ram大小都是那么大...

Re: vscode的插件platformio，目录结构该如何规划？

再回到rtthread-nano的msh功能。

之前编译后发现finsh_system_init()函数没有执行，于是手动调用这个函数，结果报__fsymtabl_start, __fsmtab_end等找不到的错误。去rtthread论坛搜，都提到了链接文件。当时没明白该去哪里找链接文件。在vsc工程目录里搜相关词也搜不到。
今天发现GD32VF103XX.lds就是链接文件，其中cbxx.lds里有相关定义，其他的没有，而我的板子正好是c8t6。把相关部分复制过来后，编译还是不行。想了想，platfromio用的是自带的lds，然后去.platformio目录下找到了相关的，把这部分复制过去。可以编译通过了，串口上也能显示msh>提示符了。不过输入没反应，可能是我串口输入部分写的有问题。

-----------------------------------------------

可以输入了，哈。

-------------------------------------------

上传一下目前的工程当个备份用。
需要注意的地方就是修改/home/any/.platformio/packages/framework-gd32vf103-sdk/RISCV/env_Eclipse下的.lds后缀的链接文件里的内容。也许platformio能指定用bsp里的lds，但我不知道怎么设置。并且，rtthread给的bsp里的，只有cbxx.lds里有__fsymtab_start相关部分，如果用的是c8t6的话，需要将c8xx.lds里的复制那部分进去。
