Greetings I think I may need to build a boot loader for my prototype, which is a s mart phone. It is Samsung Note 3; it has Qualcomm SOC msm8974 based on ARM architecture. I think I may need to do this so I have more freedom on my ac cess to service, which may be limited after the kernel takes over. I like t he group to please provide feedback as to whether this is a worthwhile effo rt, if anyone else has attempted it, *and* if it is even possible. It is my understanding that this platform has a primary boot loader, and then there are three secondary boot loaders. I am not clear as to which one does what ; it is intuitive that the primary does the most preliminary setup tasks. B ut why there are three stages; I have no idea. I also don't know why the st ock rom only comes with the sbl2 ( I am guessing secondary boot loader stag e 2? ). The file extension is mbn; darned if know how to open it so any hel p in this front is greatly appreciated. Like any other human being, I assum e my audience knows some of the items so please let me know if I missed som ething and I'll be glad to elaborate. So in short do you think I am on the right path, or am I completely off path and or for some reason I will run i nto a roadblock? But if I am on the right path, is there a body of work, wh ich I can leverage? By that I mean has anyone tried to port Das U-boot or s ome other boot loader for this platform? And if they have how can I get a c opy of the code or view their advice please? Regards- Sean
