openocd that comes with buildenv as a conda package fails to flash image on the FPGA flash, it looks like it has some kind of communication issue because the flash ID is detected as 0x00ffffff

Using the openocd version provided by system works correctly:

[pbinkowski@arch litex-buildenv]$ sudo openocd -f board/numato_opsis.cfg -c 'init; xc6s_print_dna xc6s.tap; jtagspi_init 0 /home/pbinkowski/projects/fx2/litex-buildenv/build/conda/lib/python3.7/site-packages/hdmi2usb/firmware/spartan6/opsis/bscan_spi_xc6slx45t.bit; jtagspi_program /home/pbinkowski/projects/fx2/litex-buildenv/build/opsis_hdmi2usb_vexriscv/image-gateware+bios+firmware.bin 0x0; exit'
