Someone know what the meaning of this line in the SVF file?
SDR 32 TDI(00000000) TDO(00019020) SMASK(FFFFFFFF) MASK(FFFFFFFF)
I tried to program "GOWIN" FPGA with lattice JTAG programmer and I don't succeed.
As I know, the JTAG programmer should be generic.
The programmer is successfully scan the device but fail in line 43 in the SVF file:
SDR 32 TDI(00000000) TDO(00019020) SMASK(FFFFFFFF) MASK(FFFFFFFF);

The meaning of the line can be found in SVF file format specification. It's expecting the data in TDO during a 32 bit data transfer and apparently seeing something different. It may be the first line checking for a specific answer, respectively a simple explanation may be that you get not response at all, e.g. due to incorrect connected JTAG adapter.
You need to decode the complete .svf file to understand what the is specifically intended by this line.

Hi,
i didn't ask about device (chip) but about FPGA board. Why you didn't program it by "Gowin Programer" ?
Gowin devices might have different chip ID from Lattice FPGA chips.
