大家好，我对一个芯片传输数据，好像数组一大就就报错，数组有9000多字节，传输就报这个错误：[ 9.063047] twi_stop()483 - [i2c1] i2c state isn't idle(0xf8)
[ 9.069504] sunxi_i2c_core_process()845 - [i2c1] STOP failed!
[ 9.076040] sunxi_i2c_do_xfer()998 - [i2c1] incomplete xfer (status: 0x38, dev addr: 0x3b)
[ 9.085342] ##### i2c_transfer addr 0xc000 , ret -70
难道内核对数据大小做了限制？有什么方法解决吗，谢谢。
自己画了块v3s的板子，spi 启动，到这卡住不走了。有哪位碰到吗？

关于gcc库的几个问，一直这个问题没整明白，哪位高人指导一下。
比如的编译器的路径在：
COLLECT_GCC=arm-poky-linux-gnueabi-gcc
COLLECT_LTO_WRAPPER=/opt/fsl-imx-x11/4.1.15-2.1.0/sysroots/x86_64-pokysdk-linux/usr/libexec/arm-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/5.3.0/lto-wrapper
Target: arm-poky-linux-gnueabi。
我现在移植一个libmad 的库，进去之后
./configure --target=arm-poky-linux-gnueabi --host=arm-poky-linux-gnueabi --build=x86_64-pc-linux-gnu --prefix=/usr
这个target, host 这个指定对不对，
这个--prefix=/usr 这个/usr是宿主机的usr，还是编译器里面的usr。这个路径怎么确定。
多谢。
直接用耳机输出没这事啊，耳机输出原来3.4 的驱动只要数据不足确实会设置寄存器静音，3.4 里没看到你这个。
大家拿串口485 一般都是怎么实现的，我是在内核串口驱动里面增加了一个.ioctl = serial_rs485_ioctl, 函数接口，然后应用程序里
rs485conf.flags = SER_RS485_ENABLED;
rs485conf.delay_rts_after_send = 1000;
rs485conf.delay_rts_before_send = 1000;
ioctl(fd, TIOCSRS485, &rs485conf);
来开启串口的485 功能。功能到是能开启，但是发现会影响调试串口的输入，TAB 键不好使了，删除键也变了，进入这个函数打印发现每次调试串口终端输入都会有这些命令：
[ 17.808074] serial_rs485_ioctl1053 - ######### port_line 0, cmd 0x5401

大家好最近弄v3s 的i2c ，发现在内核对从地址是这么处理的
/* 7-1bits addr, xxxx_xxx0 */
addr = (i2c->msg[i2c->msg_idx].addr & 0x7f) << 1;
，这要是我的从地址是0x70 , 写的时候变成了0xe0, 没法控制设备啊。我把地址强制成0x70，就可以了，这什么意思？这驱动有问题？按理说不应该啊。
static void sunxi_i2c_addr_byte(struct sunxi_i2c *i2c)
{
unsigned char addr = 0;
unsigned char tmp = 0;
if (i2c->msg[i2c->msg_idx].flags & I2C_M_TEN) {
/* 0111_10xx,ten bits address--9:8bits */
tmp = 0x78 | ( ( (i2c->msg[i2c->msg_idx].addr)>>8 ) & 0x03);
addr = tmp << 1;//1111_0xx0
/* how about the second part of ten bits addr? Answer: deal at twi_core_process() */
}
else {
/* 7-1bits addr, xxxx_xxx0 */
addr = (i2c->msg[i2c->msg_idx].addr & 0x7f) << 1;
}
/* read, default value is write */
if (i2c->msg[i2c->msg_idx].flags & I2C_M_RD) {
addr |= 1;
}

https://blog.csdn.net/wavemcu/article/details/7202908记起来了， 当时听xboot说和 busybox 有关, 你可以深入研究一下。
按照网上说的，修改了busybox 下面两个文件，重新编译了，中文还是显示 ??? 号。瞎了。

下载 mobaxterm, 右击终端 -> Change terminal setting ...
我用putty 登录的，是这个配置，也不行。只能显示问号。还有什么其他地方需要配置的。内核里已经选上中文支持了。

最近在编译pjsip,我的gcc按照目录是/opt/gcc-linaro-7.4.1-2019.02-x86_64_arm-linux-gnueabihf，我在目录下find ,sinlinx@ubuntu://opt/gcc-linaro-7.4.1-2019.02-x86_64_arm-linux-gnueabihf$ sudo find . -name libpthread.so.0

什么错误

这个里面全是CPP 文件。而且我编了一个简单的cpp文件，arm-linux-gnueabihf-g++ -W -o hello-cpp hello-c++.cpp，显示没有arm-linux-gnueabihf-g++编译器。编译c是没有问题的。
你的 ubuntu 是 32bit / 64bit 版本?
https://releases.linaro.org/components/toolchain/binaries/6.3-2017.02/arm-linux-gnueabihf/
64bit ，发现用root 编译没问题。晕菜。这个礼拜在一直pjsip 搞死了。咋sip 用configure 出现这个提示
./configure --prefix=/home/sinlinx/SIN-V3s/pjsip/pj-out --host=arm-linux-gnueabihf --disable-video --disable-ffmpeg --disable-v4l2 --disable-openh264 --disable-libyuv --disable-libwebrtc

不能创建这个，我还特意用root 配置。谢谢。
交叉编译现在还是有点蒙圈，哪位解答一下。谢谢
我下载了gcc-linaro-6.3.1-2017.02-x86_64_arm-linux-gnueabihf.tar，解压到了/opt目录下
sinlinx@ubuntu://opt/gcc-linaro-6.3.1-2017.02-x86_64_arm-linux-gnueabihf$ ls
arm-linux-gnueabihf bin gcc-linaro-6.3.1-2017.02-linux-manifest.txt include lib libexec share
然后设置PATH:
export PATH=/opt/gcc-linaro-6.3.1-2017.02-x86_64_arm-linux-gnueabihf/bin:$PATH
重启，用arm-linux-gnueabihf-gcc -v 查看
sinlinx@ubuntu://opt/gcc-linaro-6.3.1-2017.02-x86_64_arm-linux-gnueabihf$ arm-linux-gnueabihf-gcc -v
Using built-in specs.

这一下出了这么多，哪个才是，如果第三方APP 要独立编译的话，是把编译器的路径指到这里来吗？或者直接bash.bashrc把路径加到这里来。谢谢。
你先去试一试我的一键生成吧: https://whycan.cn/t_2169.html
我现在编译一个自己应用程序。但是报错.pjsua2-lib-arm-unknown-linux-gnueabihf.depend:1: *** missing separator. Stop.
，但是怎会显示arm-unknown-linux-gnueabihf，”unknown”这是没有指定什么平台吗？
我这的PATH 变量
/opt/gcc-linaro-6.3.1-2017.02-x86_64_arm-linux-gnueabihf/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games
有点晕。晕哥看看啥问题。多谢。
晕哥，为什么我的\rootfs 目录下没有include 文件夹。我在编译pjsip，需要编译alsa 库。谢谢。
这几天买了一个v3s的开发板。编译的都快疯了。编译demo 老提示
make: arm-buildroot-linux-uclibcgnueabihf-gcc: Command not found，
我是直接在DEMO 下make 的。demo 的makefile 是这么写的
CROSS_COMPILE ?= arm-buildroot-linux-uclibcgnueabihf-
CPU = cortex-a7
FPU = fpv4-sp-d16
AS = $(CROSS_COMPILE)as
LD = $(CROSS_COMPILE)ld
CC = $(CROSS_COMPILE)gcc
CXX = $(CROSS_COMPILE)g++
CPP = $(CC) -E
AR = $(CROSS_COMPILE)ar
NM = $(CROSS_COMPILE)nm
STRIP = $(CROSS_COMPILE)strip
OBJCOPY = $(CROSS_COMPILE)objcopy
OBJDUMP = $(CROSS_COMPILE)objdump
RANLIB = $(CROSS_COMPILE)ranlib
SIZE = $(CROSS_COMPILE)size
我现在就是搞不明白这个CROSS_COMPILE 路径在哪指定？高人帮忙
