Dir my friends,
I'm an application engineer. I'm in project ARM lh79525. I searched on internet about embedded Linux for arm lh79525 and I see a little document about arm linux for it.I have some trouble with embedded Linux on Lh79525. I hope that everybody will help me.
First, i illustrator my project. I use u boot is bootloader. My board boot is ok.
