快速编译第三步出现问题

执行命令：make csky_gx6605s_defconfig 报错： make -C /home/czq/buildroot/buildroot-ded3f9954f158b5d9cd08ae76749eade72fcca3a O=/home/czq/buildroot/ make[1]: Entering directory '/home/czq/buildroot/buildroot-ded3f9954f158b5d9cd08ae76749eade72fcca3a' Makefile:926: Please configure Buildroot first (e.g. "make menuconfig"). Stop. make[1]: Leaving directory '/home/czq/buildroot/buildroot-ded3f9954f158b5d9cd08ae76749eade72fcca3a' Makefile:52: recipe for target 'csky_gx6605s_defconfig' failed make: [csky_gx6605s_defconfig] Error 2

请问这样应该怎么解决？

我的情况还不一样：先执行 make CONF=thead_610_compat_next_glibc_br_defconfig 跑了很久（澡都洗完了还没跑完）没问题

然后执行make 报错： make -C /home/akira/code/test/buildroot/buildroot/buildroot-ded3f9954f158b5d9cd08ae76749eade72fcca3a O=/home/akira/code/test/buildroot/buildroot/ make[1]: 进入目录“/home/akira/code/test/buildroot/buildroot/buildroot-ded3f9954f158b5d9cd08ae76749eade72fcca3a” Makefile:926: Please configure Buildroot first (e.g. "make menuconfig")。停止。 make[1]: 离开目录“/home/akira/code/test/buildroot/buildroot/buildroot-ded3f9954f158b5d9cd08ae76749eade72fcca3a” Makefile:52: recipe for target 'all' failed make: [all] Error 2

从错误信息看，似乎是要make menuconfig，明天试试看。

换成 make CONF=thead_610_compat_4.9_glibc_br_defconfig 编译成功了~

@guoren83

还有问题想请教一下你：现在的情况是，用make CONF=thead_610_compat_4.9_glibc_br_defconfig 已经成功生成了uImage，gx6605s.dtb，rootfs.ext2，也查其他资料生成了usb.img，我生成的这个usb.img写到U盘后可以启动，因为USB串口正常显示了信息，但是串口最后并没有显示Linux console登录提示，也不响应输入，HDMI也没有任何显示，但是我用官网提供的usb.img，HDMI是可以正常显示Linux console的，也可以正常用键盘操作，请问这个情况应该办？

以下是串口输出的所有信息：

找到原因了，将gx6605s.dts.txt文件中： bootargs = "console=ttyS0,115200 rootwait init=/sbin/init root=/dev/nfs rw nfsroot=192.168.101.200:/tmp/rootfs_nfs,v3,tcp,nolock ip=192.168.101.23";

改成下面这样就能用串口进入console了： bootargs = "console=ttyS0,115200 init=/sbin/init root=/dev/sda2 rw rootwait";

那么问题又来了，如果想启用framebuffer，用HDMI输出，应该怎么设置呢？

厉害！

这是 fb 的 buildroot 仓库和配置 https://github.com/c-sky/buildroot/blob/master_backup/configs/csky_610_gx6605sfb_4.9_uclibc_br_defconfig

这是 fb driver https://github.com/c-sky/addons-linux/tree/master/addons/drivers/video/fbdev/nationalchip

还有问题想请教一下你：现在的情况是，用make CONF=thead_610_compat_4.9_glibc_br_defconfig 已经成功生成了uImage，gx6605s.dtb，rootfs.ext2，也查其他资料生成了usb.img，我生成的这个usb.img写到U盘后可以启动，因为USB串口正常显示了信息，但是串口最后并没有显示Linux console登录提示，也不响应输入，HDMI也没有任何显示，但是我用官网提供的usb.img https://c-sky.github.io/docs/quick-run.html，HDMI是可以正常显示Linux console的，也可以正常用键盘操作，请问这个情况应该办？

以下是串口输出的所有信息：

找到原因了，将gx6605s.dts.txt文件中： bootargs = "console=ttyS0,115200 rootwait init=/sbin/init root=/dev/nfs rw nfsroot=192.168.101.200:/tmp/rootfs_nfs,v3,tcp,nolock ip=192.168.101.23";

改成下面这样就能用串口进入console了： bootargs = "console=ttyS0,115200 init=/sbin/init root=/dev/sda2 rw rootwait";

那么问题又来了，想启用framebuffer，用HDMI输出，应该怎么设置呢？

还有问题想请教一下你：现在的情况是，用make CONF=thead_610_compat_4.9_glibc_br_defconfig 已经成功生成了uImage，gx6605s.dtb，rootfs.ext2，也查其他资料生成了usb.img，我生成的这个usb.img写到U盘后可以启动，因为USB串口正常显示了信息，但是串口最后并没有显示Linux console登录提示，也不响应输入，HDMI也没有任何显示，但是我用官网提供的usb.img https://c-sky.github.io/docs/quick-run.html，HDMI是可以正常显示Linux console的，也可以正常用键盘操作，请问这个情况应该办？

以下是串口输出的所有信息：

找到原因了，将gx6605s.dts.txt文件中： bootargs = "console=ttyS0,115200 rootwait init=/sbin/init root=/dev/nfs rw nfsroot=192.168.101.200:/tmp/rootfs_nfs,v3,tcp,nolock ip=192.168.101.23";

改成下面这样就能用串口进入console了： bootargs = "console=ttyS0,115200 init=/sbin/init root=/dev/sda2 rw rootwait";

那么问题又来了，想启用framebuffer，用HDMI输出，应该怎么设置呢？

(手动滑稽害怕)，buildroot我都是瞎摸索出来的，恐怕整合驱动就力不从心了 (:з」∠)

@akiyamaakira: same as you I have problem on displaying on HDMI output(framebuffer configuration). Did you solve this problem? could you please help me how I can add hdmi display output(framebuffer enable) to my OS image?

I recieved error during building this branch and this is while now I can build OS Image using master branch. The only problem seems is about initrd. same as your syslog output, there are:

Jan  1 00:00:04 buildroot user.err kernel: [    0.000000] initrd not found or empty
Jan  1 00:00:04 buildroot user.err kernel: [    0.000000]  - disabling initrd

error which there is not in provided reference usb.img! then seems there is some thing wrong with bootarg. even when I changed to the your suggestion there is no improovement.

cd to directory: my_output/build/host-gdb-4ecb98fbc2f94dbe01b69384afbc515107de73df/gdb

and edit file: location.c

in line 527: if (argp == NULL || argp == '\0' || argp[0] != '-' || !isalpha ((argp)[1]) || ((argp)[0] == '-' && (*argp)[1] == 'p')) return NULL;

modify || argp == '\0' to || argp == NULL

will fix the error
