Is there anybody debug Kinetis with J-LINK?
I got a problem.J-Link Commander print as below:
SEGGER J-Link Commander V4.40a ('?' for help)Compiled Dec 16 2011 20:52:58DLL version V4.40a, compiled Dec 16 2011 20:52:42Firmware: J-Link ARM V8 compiled Dec 6 2011 18:57:44Hardware: V8.00S/N: 20100214Feature(s): RDI,FlashDL,FlashBP,JFlash,GDBFullVTarget = 3.287VInfo: TotalIRLen = 4, IRPrint = 0x01Info: ARM AP[0]: 0x24770011, AHB-APInfo: ARM AP[1]: 0x001C0000, JTAG-AP****** Error: No APB-AP found.No devices found on JTAG chain.

I have tried the command "unlock kinetis", but does not work.
J-Link>unlock kinetisFound SWD-DP with ID 0x2BA01477Unlocking device...Timeout while unlocking device.J-Link>unlock kinetisFound SWD-DP with ID 0x2BA01477Unlocking device...Timeout while unlocking device.
I am wondering if my board is OK. Any suggestion for Me?
Did you find a solution?
When use SWD interface, cause there is no reset signal to JLINK
Solution:
Open jlink. Exe command tool, when hint as follows, must pull low CPU reset pin
Pull low reset pin, click "yes", will be prompted to find Cortex-the M4, Run command "unlock kinetis" then unlock successful!
i have the same problem,and i try "unlock kinetis","erase_all_pin.jlk",but it still can't be solved.why?
Is there anybody can help me ?
Or just give me some suggestion ... Thx
