We have our in-house hardware design using the ATSAM4LC8C processor
JLINK is failing to detect the processor via JTAG
In Jlink commander at the 'i' command I get the response:
J-Link>i
Info: TotalIRLen = 0, IRPrint = 0x00
Info: TotalIRLen = 0, IRPrint = 0x00
Info: TotalIRLen = 0, IRPrint = 0x00
****** Error: AT91SAM4L (connect): Failed. Could not identify device.
JTAG Id: 0x00000000: INVALID
J-Link>
We have checked the physical connections of TCK, TDI, TMS, TDO, RESET and we can see activity on these lines on an oscilloscope.
We have not connected TRST.
Also using the JTAG-Hardware commands in JLINK we have toggled these lines to verify connection of TCK, TMS, TDI, RESET
Any suggestions why Jlink is failing to detect the processor?
Thanks
