And in guest os, the hardware is synopsys dw_apb_uart which is compatible with 16550. +when it access low 8 registers, it works ok. but it may access high address(0x8c) which serial.c not defined, then fail occur. + +Is there anyway to handle this, access address which device not defined, expect it no handle, but not cause system crash. like read is zero and write ignore. |
