Cross Compiler and Toolchain Download Guide<\/strong><\/span><\/span><\/p>\n

Our next task is cross compiler and toolchain download. To cross-compile Linux kernel, Linux application, and kernel modules to ARM Cortex Ax architecture, we need a cross compiler.<\/span><\/p>\n

Because the SOC which is there on our beagle bone black hardware is AM335x, which is from Texas instruments, this SOC is based on the ARM Cortex A8 processor of ARMv7 architecture. That’s a reason why we need to have the cross compiler because we need to cross-compile all our Linux source code, the application, and the kernel modules.<\/span><\/p>\n

We are going to download cross compiler from linaro.org. <\/span><\/p>\n

You have to just head over to your browser and just type in the Google linaro toolchain, and follow this link linaro.org > downloads as shown in Figure 1.<\/span><\/p>\n

    \n
  1. Open your web browser and search for “Linaro Toolchain” on Google.<\/span><\/li>\n
  2. Navigate to the official Linaro website by clicking on the link labeled “linaro.org > downloads<\/a>” as shown in Figure 1.<\/span><\/li>\n<\/ol>\n
