[OpenOCD-devel] flyswatter2 vs artix 7

[Enrico W. m. IT c. <in...@me...>]

Hi folks,


I'd like to program a new bitfile to an artix-7 (xc7a50t) via
openocd + flyswatter2, but having trouble connecting to it:

(devuan)nekrad@orion:~/.usr/openocd/bin$ ./openocd -f 
~/.usr/openocd/share/openocd/scripts/interface/ftdi/flyswatter2.cfg -c 
"adapter_khz 6000" -c "transport select jtag" -f 
~/.usr/openocd/share/openocd/scripts/cpld/xilinx-xc7.cfg

adapter speed: 6000 kHz
jtag
xc7_program
Info : clock speed 6000 kHz
Error: JTAG scan chain interrogation failed: all ones
Error: Check JTAG interface, timings, target power, etc.
Error: Trying to use configured scan chain anyway...
Error: xc7.tap: IR capture error; saw 0x3f not 0x01
Warn : Bypassing JTAG setup events due to errors
Warn : gdb services need one or more targets defined

Do I need some additional configuration ?
