TE0790 Identification

TE0790 will be delivered in 2 different Variant, which differs only in FTDI EEPROM configuration.

TE0790-xx FTDI is programmed with Digilent License key to be usable with AMD Tool(Vivado, Vitis, Petalinux)
TE0790-xx-L FTDI has default configuration

*xx means PCB Revision

TE0790 DIP configuration for stand alone power up

Programmer Power supply setting depends on connected carrier on J2 Pinheader. To check Programmer without connected FPGA Hardware set following dip settings before connecting USB

S2 DIP	Position	Description
1	ON	Normal mode
2	OFF	Must be in OFF state always.
3	OFF	Power VIO from pin header J2(CPLD Bank voltage)
4	ON	Power 3.3V from USB (Use USB supply stand alone or in case TE0790 J2-5 Pin is not supplied by carrier)

Identification Methods

Label

TE0790 with green dot sticker are factory programmed with Digilent/AMD License

TE0790-xx	TE0790-xx-L

Reliability of identification: Uncertain, in case sticker was removed.

Device Manager

FT2232H on TE0790 has two configurable ports which are default show as COM port.

TE0790 with Digilent/AMD License shows normally only one COM Port TE0790 without License key show two ports.

TE0790-xx	TE0790-xx-L

Reliability of identification: Uncertain, in case FTDI was reprogrammed manually.

USB Viewer

Part of the EEPROM content is visible with Microsoft USB viewer.
