amir57bs Posted January 7, 2017 Share Posted January 7, 2017 hi Guys I would like to know is there any bit perfect music server project on ARM processor/Ubuntu platform? Linux optimized Ubuntu (real Time kernel) ARM Processor Cortex-R8 Link to comment

Richard Dale Posted January 7, 2017 Share Posted January 7, 2017 You don't say which ARM architecture you want, My apologies, you do say 'ARM Processor Cortex-R8', but I found that is ARMv7-R architeture when I searched for it. Is that different to armv7, what does the difference between ARMv7-R and ARMv7 mean in term of binary compatibiltiy?

Richard Dale Posted January 7, 2017 Share Posted January 7, 2017 i dont know about that. just i try to find information about this project.linux is fun to play Yes, I agree it is fun to learn about Linux! I would recommend MPD as a bit perfect music server as per your original question. If you can install Ubuntu on your target device, I'm pretty sure you will be able to add MPD with apt.

Is that different to armv7, what does the difference between ARMv7-R and ARMv7 mean in term of binary compatibiltiy? I suspect it's an Allwinner R8 chip, which has a Cortex-A8 CPU. ARMv7-R CPUs are not intended to run a full OS like Linux. Link to comment

mansr Posted January 8, 2017 Share Posted January 8, 2017 some guys think ARM processors are not very powerfull with linux and they think ARM processors are better for microcontrollers. There is a wide range of ARM processors for various different applications. Cortex-R processors can't run Ubuntu because they don't have an MMU. An ARMv7-A CPU is required for that. You'd get much better advice if you told us exactly what system you're using. Link to comment
Jud Posted January 8, 2017 Share Posted January 8, 2017 some guys think ARM processors are not very powerfull with linux and they think ARM processors are better for microcontrollers. Amir, "some guys" think a lot of things. When people discuss things in general terms, you get many opinions that may or may not be helpful in your own situation. mansr is right, the more you tell people here about your specific equipment, the better advice they may be able to give.
