ARM processor
Console connection
- use a USB type-A to type-A cable to connect from CDM eSATA connector to computer USB connector.
- on linux, two /dev/ttyUSB ports will show up (FTDI USB-serial chip)
- use minicom (or other tool) to connect with these serial port settings:
Serial Device : /dev/ttyUSB2 Bps/Par/Bits : 115200 8N1 Hardware Flow Control : No Software Flow Control : No
- type "enter" several times to get the "#" root shell prompt
- on power cycle, observe the output from u-boot and from the linux kernel https://daqshare.triumf.ca/~olchansk/VME-CDM/cdm-boot.txt
