+g +``` + +其中`ifaddr`是设置pmon设置网络的命令，`syn0`表示第一个网卡。然后从tftp的主机上加载`rtthread.elf`文件，此时主机必须有tftp服务器。`g`表示程序跳转运行。 + +而后可以看到rtthread程序正常的运行。 + +``` + zero at v0 v1 a0 a1 a2 a3 + 00000000 00000000 00000000 00000000 00000003 aafffea8 8f800000 8f1371d0 + t0 t1 t2 t3 t4 t5 t6 t7 + 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 + s0 s1 s2 s3 s4 s5 s6 s7 + 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 + t8 t9 k0 k1 gp sp s8 ra + 00000000 00000000 00000000 00000000 00000000 aafffe88 00000000 8f0b1418 +Current SR: 0x10008080 + + \ | / +- RT - Thread Operating System + / | \ 4.0.3 build Apr 7 2020 + 2006 - 2020 Copyright by rt-thread team +Hi, this is RT-Thread!! +msh > +``` + +## 4.开机自动启动 + +在调试阶段，可以利用脚本，在pmon阶段从TFTP服务器上获取固件，然后引导启动。这样可以节省开发配置的时间。具体的步骤如下： + +**第一步：** +设置开发板的IP地址，在进入pmon的控制台后，输入`set ifconfig syn0:10.1.1.100`。其中`syn0`后面的ip地址为开发板的ip地址，与存放rt-thread固件的TFTP的服务器IP地址在**同一网段**。 + +**第二步：** + +进入龙芯的Debian系统，用管理员权限进入，输入用户名`root`，密码`loongson`。并且修改boot分区下的boot.cfg文件。增加如下： + +``` +title TFTPBOOT + kernel tftfp://10.1.1.118/rtthread.elf + args console=tty root=/dev/sda2 + initrd (wd0,0)/initrd.img +``` + +其中`tftfp://10.1.1.118/rtthread.elf`中的`10.1.1.118`为tftp服务器的ip地址。 + +**第三步：** + +电脑开启TFTP服务器，将路径指向存放有ls2k的rt-thread固件的目录下。 + +以上三步完成之后，重启系统，就可以省略每次都需要进入pmon的输入命令的麻烦，板子上电后，可以自动从系统TFTP服务器中获取固件，然后启动，大大提高调试代码效率。 + +## 5. 支持情况 + +| 驱动 | 支持情况 | 备注 | +| ------ | ---- | :------: | +| UART | 支持 | UART0| +| GPIO | 支持 | - | +| PWM | 支持 | - | +| GMAC | 支持 | 网卡驱动 | +| RTC | 支持 | - | + +## 6. 联系人信息 + +维护人：[bernard][4] + +[1]: http://ftp.loongnix.org/loongsonpi/pi_2/doc +[2]: https://pan.baidu.com/s/17dbdOE4NAJ-qEW7drVRq2w +[3]: http://ftp.loongnix.org/embedd/ls2k/ +[4]: https://github.com/BernardXiong diff --git a/bsp/ls2kdev/SConscript b/bsp/ls2kdev/SConscript new file mode 100644 index 0000000000..0992612410 --- /dev/null +++ b/bsp/ls2kdev/SConscript @@ -0,0 +1,12 @@ +from building import * + +cwd = GetCurrentDir() +objs = [] +list = os.listdir(cwd) + +for d in list: + path = os.path.join(cwd, d) + if os.path.isfile(os.path.join(path, 'SConscript')): + objs = objs + SConscript(os.path.join(d, 'SConscript')) + +Return('objs') diff --git a/bsp/ls2kdev/SConstruct b/bsp/ls2kdev/SConstruct new file mode 100644 index 0000000000..66b5ae8603 --- /dev/null +++ b/bsp/ls2kdev/SConstruct @@ -0,0 +1,39 @@ +import os +import sys +import rtconfig + +from rtconfig import RTT_ROOT + +sys.path = sys.path + [os.path.join(RTT_ROOT, 'tools')] +from building import * + +TARGET = 'rtthread.' + rtconfig.TARGET_EXT + +DefaultEnvironment(tools=[]) +env = Environment(tools = ['mingw'], + AS = rtconfig.AS, ASFLAGS = rtconfig.AFLAGS, + CC = rtconfig.CC, CCFLAGS = rtconfig.CFLAGS, + CXX = rtconfig.CXX, CXXFLAGS = rtconfig.CXXFLAGS, + AR = rtconfig.AR, ARFLAGS = '-rc', + LINK = rtconfig.LINK, LINKFLAGS = rtconfig.LFLAGS) +env.PrependENVPath('PATH', rtconfig.EXEC_PATH) +env['ASCOM'] = env['ASPPCOM'] + +Export('RTT_ROOT') +Export('rtconfig') + + +# prepare building environment +objs = PrepareBuilding(env, RTT_ROOT) + +rtconfig.LFLAGS += " -Ttext 0xffffffff80200000" +env.Replace(LINKFLAGS = rtconfig.LFLAGS) + +if GetDepend('RT_USING_FPU'): + env['CCFLAGS'] = env['CCFLAGS'].replace('-msoft-float', '-mhard-float') + env['ASFLAGS'] = env['ASFLAGS'].replace('-msoft-float', '-mhard-float') + env['CXXFLAGS'] = env['CXXFLAGS'].replace('-msoft-float', '-mhard-float') + env['LINKFLAGS'] = env['LINKFLAGS'].replace('-msoft-float', '-mhard-float') + +# make a building +DoBuilding(TARGET, objs) diff --git a/bsp/ls2kdev/applications/SConscript b/bsp/ls2kdev/applications/SConscript new file mode 100644 index 0000000000..fb5ce2ce93 --- /dev/null +++ b/bsp/ls2kdev/applications/SConscript @@ -0,0 +1,8 @@ +from building import * + +cwd = GetCurrentDir() +src = Glob('*.c') + +group = DefineGroup('Applications', src, depend = ['']) + +Return('group') diff --git a/bsp/ls2kdev/applications/main.c b/bsp/ls2kdev/applications/main.c new file mode 100644 index 0000000000..bd975f4825 --- /dev/null +++ b/bsp/ls2kdev/applications/main.c @@ -0,0 +1,17 @@ +/* + * Copyright (c) 2006-2020, RT-Thread Development Team + * + * SPDX-License-Identifier: Apache-2.0 + * + * Change Logs: + * Date Author Notes + * 2020-04-05 bigmagic first version + */ + +#include <rtthread.h> + +int main(int argc, char** argv) +{ + rt_kprintf("Hi, this is RT-Thread!!\n");
