Hi,I am a beginner in kernel porting. I am trying to port Linux kernel (version- 4.9.22) on Custom SoC (cpu = arm1176jzfs based) for custom evaluation Board. I am having ARM Prime cell pl011 UART in my SoC. And it is physically mapped to 0x5800_1000 address. While i am trying to use it as Debug UART, kernel is asking for its virtual Address. How should i configure this option.i.e: -> Kernel low-level debugging functions -> kernel low-level debugging port (Kernel low-level debugging on via ARM Ltd PL01x Primecell UART) (0x58001000) Physical base address of debug UART (??) Virtual base address of debug UART
Thanks,
Vivek T.
In Kernel configuration, enable CONFIG_DEBUG_INFO (Kernel Hacking -> Compile-time checks and compiler options). -Compile the kernel.
