Can't load 3.5.3 on pi b+ plus

The file piaware-config.txt exists only in Piaware SD card image. Raspbian image, with package install of piaware+dump1090-fa, does not have it. You have to use file /etc/piaware.conf . In package install, for editing dump1090-fa related parameters such as gain , you have to edit file /etc/default/dump1090-fa
