What is the virtual address of UART2 in the basic YOCTO build for LS1021ATWR?
Hi, I'm trying to bring up Linux on a custom board based on the LS1021ATWR dev kit and SDK. However, my console access is UART2 (0x021D0500). I would like to configure Linux to ouput early debug info on this port. There's a similar post here for the LS1021A-PB: Early UART Debugging on ttyS0 (Bank-0) LS1021A-PB. I've been able to enable DEBUG_LL and compile printasci into head.S, but no output yet.
When configuring DEBUG_LL, it seems I must set the items CONFIG_DEBUG_UART_PHYS and CONFIG_DEBUG_UART_VIRT as well. How do I determine the address for CONFIG_DEBUG_UART_VIRT?
