I have a JTAG-chain consisting of a VF6XX_A5 MCU and a Igloo nano FPGA. I am using J_Link PlUS, and I know that I can not expect to program the FPGA out of the box, but shouldn't I be able to program the MCU, even though there are a FPGA on the chain?
The chain is configured as following:
TDI --> VF6XX_A5 (IRlen 4) --> Igloo nano (IRlen 8) -->
TDO <--------------------------------------------------------
I am using J_link Commander to try to connect to the MCU.
The setting I am using is
Device: VF6XX_A5,
TIF: JTAG,
JTAGConf: -1,-1 (I have tried 0,0 which should be the correct according my setup)
Speed 4000 KHz
But the respons i get is:
Device "VF6XX_A5" selected.
TotalIRLen = 12, IRPrint = 0x019D
TotalIRLen = 12, IRPrint = 0x019D
TotalIRLen = 12, IRPrint = 0x019D
TotalIRLen = 12, IRPrint = 0x019D
****** Error: CPU-TAP not found in JTAG chain
TotalIRLen = 12, IRPrint = 0x019D
TotalIRLen = 12, IRPrint = 0x019D
TotalIRLen = 12, IRPrint = 0x019D
TotalIRLen = 12, IRPrint = 0x019D
****** Error: CPU-TAP not found in JTAG chain
Can not connect to target.
Can anyone help me? I am out if ideas..
