Build Instructions

CTAG face2

Hardware

For connecting the BeagleBoard-X15 and CTAG face2|4 Audio Card an extension cape has been created by my mentor Robert Manzke. All hardware design files (created with KiCad) can be found on CTAG face2|4 GitHub repo.

Linux Driver

Note: The drivers has been merged in the official BeagleBoard kernel and are included in the SD images.

Kernel Compilation

1. Compile kernel according to Kernel Compilation Guide in ctag-face-2-4 repo
2. Transfer zImage, dtbs, modules/firmware and config to BeagleBoard-X15 SD-Card
3. Modify/Add uname_r=4.1.18+ to /boot/uEnv.txt
4. Modify/Add dtb=am57xx-beagle-x15-ctag.dtb to /boot/uEnv.txt
5. Reboot
6. Generate initramfs (update-initramfs -c -k $(uname -r)

DSP Library (libdsp-x15)

Prerequisites

Default Debian Images of BeagleBoard already include most of the required build tools (e.g. g++, make, opencl, ...). The library can be easily built using CMake (available in Debian repository). For execution TI DSPLIB is required, which is included in the BeagleBoard images. Simply create a symlink to /usr/share/ti/examples/opencl/dsplib_fft/dsplib.ae66 in code/libdsp-x15.

Build Process

1. git clone https://github.com/henrix/libdsp-x15.git && cd libdsp-x15
2. cd code/libdsp-x15
3. cmake .
4. make
5. sudo cp libdsp-x15.so /usr/lib/
6. sudo ldconfig
