Hello everyone!
I have a problem, again: it's with booting Kernel
I build own Kernel with PRU support and followed these steps:
1) Installed SDK evm-02.00.00.00-Linux-x86
2) Then, i installed PRU Software Support Package and edit .configure file
3) Then, i followed this guide: processors.wiki.ti.com/.../Linux_Kernel_Users_Guide
3.1) i completed this "Installing the Kernel Image and Device Tree Binaries" in dir /home/rootfs/boot
3.2) i get "file system" from tar. /home/rootfs
3.3) i completed "Installing the Kernel Modules" in /home/rootfs
4) Then i ran SD card script --> chosen custom images.
4.1) Because I do not have MLO and u-boot, i take them from <sdk-path>/board-support/prebuild-images. How to build own MLO and u-boot? (this guide I didn't understand
5) Insert SD card on board and power on
