Thanks It is hard to answer your questions. Many parts play with each other. ASo= far I have following questions: - why do you change boot loader? - why do you use old kernels? - why you do not use devicetree? - what is your memory layout? Where is loaded u-boot and where should be = loaded kernel. Is kernel compressed? Where it will be extracted?
