Hello List,
I am trying to install current snapshot on a Raspberry 3 B. I have problems
setting up the serial communication needed to access the installer. I connected
the serial pins (6,8,10) to the serial port of my PC and set parameters to
115200/8N1. But I only see garbage on the screen. While googling for a solution
I found some hints about the Raspi using bizarre baud rates depending on the
system clock.
Following is my boot/config.txt with the core_freq line added by me:
arm_control=0x200
enable_uart=1
core_freq=250
device_tree_address=0x100
kernel=u-boot.bin
Of course I tried different baud rates, but to no avail. I am using minicom on
a intel PC running Mac OS.
Is this still a known issue? I found no hints about this in the OpenBSD install
documents for ARM.
Can someone please help?

115200 8N1 works for me. Do you have the a 3.3V serial adapter? That is vital.
See e.g. https://elinux.org/RPi_Serial_Connection#Console_serial_parameters

So... the obvious (to me) question is what happens if you delete the
core_freq=250 line from your config.txt and reboot?
are you then able to communicate with the Rpi?
