2017-11-27 Thread Jean-Christophe DUBOIS
Hi, I am using Qemu to emulate a Leon3 based board. In the software I am running on top of Qemu, I am mapping devices to a virtual address using MMU table. Now I am experimenting some issues when I am trying to access some device (here the UART port at 0x8100) through the MMU mapping (wi
