TDO Mismatch
I'm using a NodeMCU (ESP8266) to program a Xilink XC2C128, but it always gives me the error "line 0: TDO mismatch.". Am I doing something wrong or is this a bug or unsupported device?
HI
I have never tried it (or get it working) on XILINX. However it all started from libxsvf which worked for some XILINX. Also I haven't long time tried ESP8266, currently I use only ESP32 and Lattice ECP5
The reasons of not working may be many and you are on your own to fix it.
First thing of course is to split svf file into commands that ESP can cache, that's around few KB per svf command.
and then test with something else (openocd etc) does such svf with split commands work.
When I tried to split xilinx svf file on spartan-6 I had no success.
openocd could not start the svf split bitstream (although I didn't get TDO mismatch, but just split svf bitstream didnt work from openocd).
If it doesn't work from openocd I guess it's a verly small chance for it to work for anything else like libxsvf-esp...
