JTAG chain not seen unless factory_load switch is set

Thanks Dave,

I will work on it as a second priority. Here is the URL http://www.altera.com/products/devkits/altera/kit-arria-v-starter.html which

will point you to a picture as well. As you say, the System Controller MAX® V 5M2210ZF256C4N device and I was not aware that it had internal FLASH.

The FLASH consista of 2 x 1Gb Intel FLASH components which share USER, Factory FPGA configurations, NIOS executable code and some other items.
