335x uboot编译问题

LONGFEI LI1

各位好，求帮忙看看这个编译问题是怎么回事，谢谢：

我从TI官网下载了335x最新的uboot源码和工具链：www.ti.com/.../PROCESSOR-SDK-AM335X

并且按照官网上找到的关于uboot的指导手册操作编译，操作过程如下（工具链路径我使用了绝对路径，没有配置PATH变量）：

make CROSS_COMPILE=/home/llf/gcc-linaro-6.2.1-2016.11-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-  distclean

rm -rf am335x_evm/

make CROSS_COMPILE=/home/llf/gcc-linaro-6.2.1-2016.11-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf- O=am335x_evm am335x_evm_defconfig

make CROSS_COMPILE=/home/llf/gcc-linaro-6.2.1-2016.11-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf- O=am335x_evm

最后这一步编译会出现下面的问题：

../arch/arm/lib/memset.S: Assembler messages:
../arch/arm/lib/memset.S:46: Error: thumb conditional instruction should be in IT block -- `stmiage ip!,{r1,r3,r8,lr}'

../arch/arm/lib/memset.S:123: Error: thumb conditional instruction should be in IT block -- `strblt r1,[ip],#1'
../arch/arm/lib/memset.S:124: Error: thumb conditional instruction should be in IT block -- `strble r1,[ip],#1'
make[2]: *** [arch/arm/lib/memset.o] 错误 1
make[1]: *** [arch/arm/lib] 错误 2

源码完全是从官网下载下来的，没有一点改动，是否是我哪里配置的有问题呢？还请各位大神帮忙看看这个问题如何解决，谢谢。

    在CMAKE配置中的参数CMAKE_CXX_FLAGS_RELEASE 后添加”-Wa,-mimplicit-it=thumb”，依然存在问题可考虑在CMAKE_CXX_FLAGES后也添加此内容。

    大侠，能不能指导下CMAKE配置文件在什么地方？对这个完全无认识，求指点，谢谢。

    先 export PATH=$HOME/gcc-linaro-4.9-2015.05-x86_64_arm-linux-gnueabihf/bin:$PATH
    再 运行
    $ make CROSS_COMPILE=arm-linux-gnueabihf- distclean
    $ make CROSS_COMPILE=arm-linux-gnueabihf- O=am335x_evm am335x_evm_defconfig
$ make CROSS_COMPILE=arm-linux-gnueabihf- O=am335x_evm
    三个步骤，会成功吗？

    Eggsy Pang,你好。

    如此执行同样不行的，不过我下载的最新的SDK里面工具链的版本已经是2016年的了：

    llf@llf-virtual-machine:~/gcc-linaro-6.2.1-2016.11-x86_64_arm-linux-gnueabihf/bin$ pwd
    /home/llf/gcc-linaro-6.2.1-2016.11-x86_64_arm-linux-gnueabihf/bin

    llf@llf-virtual-machine:~/gcc-linaro-6.2.1-2016.11-x86_64_arm-linux-gnueabihf/bin$ echo $PATH
    /home/llf/gcc-linaro-6.2.1-2016.11-x86_64_arm-linux-gnueabihf/bin:/opt/gcc-4.4.4-glibc-2.11.1-multilib-1.0/arm-fsl-linux-gnueabi/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/opt/arm-arago-linux-gnueabi/bin

    三步执行，其中前两个命令无问题，最后一个命令执行后依然会出现这个问题：

    ../arch/arm/lib/memset.S: Assembler messages:

    继续。。。。

    TI的攻城狮们，有没有人可以用最新的sdk测试下看看是否确实存在这个问题，还是我的编译环境配置的有问题。。。。

    哥们，问一下，你的那个问题解决了没？
