If you only has one device then there must only be one jtag_device entry
in the config file
#jtag scan chain
#format L IRC IRCM IDCODE (Length, IR Capture, IR Capture Mask, IDCODE)
jtag_device 8 0x1 0x1 0xfe
jtag_device 4 0x1 0xf 0xe
jtag_device 5 0x1 0x1 0x1e
should probably be
#jtag scan chain
#format L IRC IRCM IDCODE (Length, IR Capture, IR Capture Mask, IDCODE)
jtag_device 4 0x1 0xf 0xe
This is the standard entry for a STR710 / STR711 processor.
