Hi Greg, Thanks for your answer. However, my question is reading a boot parameter directly from my module because i need to know which device is selected for the console. For example if I pass "console=ttyS0,115200" and I want to get "ttyS0,115200" in my module.
The system works fine, in boot process, config_BSP is called with u-boot argument. I just wonder that I can get value of a kernel parameter so that i don't need to define my own one in my module.
