Hello,
I have been trying to debug cx3 application by using j-link, but i face a problem as below.
i already checked Debug Configurations refer to EzUsbSute_UG.pdf
i need a idea to solve it.

Hi,
I have solved the problem, so I share the solution.
Initially, the data at 0x0 address was well read as 0x78ADE1C3, but for some reason it was set to 8000 kHz,
After that, all data read/program was found to be not normal.
The time point at which it changed to 8000 kHz seemed to be the initial reset and halt operation.
So, when I set the IDE Debug Configuration as below, it was successfully debugged.
- unchecked 'Initial Reset and Halt'
Thank you
Hi,
Thank you for reply.
I use our custom board. and JTAG interface is connected by hand jumper. Because we cannot put a connector for jtag on the board because of small space.
I have connected these pins to jtag interface.
USB_1V8_1 -> VTref (1)
USB_TCK1 -> TCK (9)
USB_TMS1 -> TMS (7)
USB_TRST#1 -> nTRST (3)
USB_TDO1 -> TDO (13)
USB_TDI1 -> TDI (5)
GND1 -> RTCK (11), GND (4,6,8, 10,12,14,16,18, 20)
RESET# -> RESET (15)
Jlink adapter version is 4.3, i think it is very old. and my CX3 on the board uses 1.8V.
Thank you in advance.
