The oscilloscope must have loader 0.8 to bypass the fpga fw version check. Then it is possible to flash the fpga. Connect the cable to the fpga, without power (then turn on the oscilloscope - it should start up normally). Now you can open Download in TD and try to flash the fpga.
P.S. Do not connect the power supply from the stm32, 1.3A is not possible anyway, so it will constantly reset.
And do not forget that you must have all the pins on the STM connected, it is not enough to use just one pin, for example, TCK you must have all 3 connected through a resistor as shown in the diagram.
I also find it strange that it is reported as version 0.1.
