Hi Ákos,

did you do it? I am working with the s3board[0] (by digilent inc) and I 
using openocd with the OOCDlink-s[1] interface. The s3board has a 
FPGA(xc3s200) and PROM(xcf02s) that they are in jtag chain (JTAG[TDI] --> 
FPGA --> PROM --> JTAG[TDO]).I have a problem with autoprobing mode. The 
openocd found a one device (PROM), it not found the FPGA[2].

Can you give me any information about it? Thanks very much in advance.

Regards,

Luis
