Hi All,
I have been trying to set up, for some time now, a hardware configuration for the zedboard with a 16550 UART and petalinux. Unfortunately, when I try to boot such a system after building the petalinux kernel, it hangs during bootup. So I have two questions and one leads into the other:
1.) Has anyone been able to communicate via 16550 on a zedboard using petalinux?
2.) does anyone have any tips or ideas on why this is hanging?
the console output of the last few lines before the hang does not appear to be the cause of the issue, but I will put it here anyway:
