> **openocd 0.10.0 log**
0.10.0 is very old and there have been significant development changes to its
implementation since then.
You should probably consider using a more recent build of OpenOCD either from
your distro's software repositories or manually built from the latest OpenOCD
0.12.0+ sources.
If you do this then you may need to make some small changes to your OpenOCD
script(s).

**[tickets:#429] How to Select Daisy Chain Chip Devices**
**Status:** new
**Milestone:** 0.10.0
**Labels:** FTDI USB FPGA Daisy Chain
**Created:** Thu Apr 11, 2024 06:38 AM UTC by KooLee

I'm having problems programming FPGAs with FT2232H+OpenOCD, I don't know how to
solve it, I hope enthusiastic people in the community can help me out.
According to Xilinx UG470 manual, FPGA supports JTAG daisy chaining.

Please tell me how to select the specified FPGA device in openocd.
The programmer device I am using is FT2232H.
