I've been to set up a new Zybo board but I'm stuck with a serial port issue. I built my design with the provided board files in Vivado 2017.4. I tried a simple "hello world" in SDK but only got a bunch of unprintable characters. I have Tera Term set up for 115200, 8-bit, 1 stop, no parity. I tried Putty as well and had the same results. I verified the Vivado project is using UART1 MIO48..49.
I intermittently can get the correct initialization message from the preloaded QSPI image, but most times it's unprintable characters.
I also tried the pre-built Linux from the 2017.4 Zybo Petalinux BSP with the same result. It's definitely booting, but the terminal output is unprintable characters.
Other things to note:
* I'm running off USB power. I'm plugged directly into my laptop
* Sometimes pressing the Reset button makes the PGOOD LED flicker until power cycled
