Hello all,
I am using a Fujistu MB9DF126 evaluation board (see mcu.emea.fujitsu.com/mcu_tool/…SK-MB9EF120-002-JLINK.htm) together with a Segger J-Link (JTAG SWD + SWO) debugger.
I am able to flash my project by means of Fujitsu SOC Wizard but I have problems when I debug with Keil uVision v4.23.
I manage to connect with uVision but when I start to step through the code I get the following J-Link error: "Could not stop Cortex-M device! Please check the JTAG cable.".
The error message sounds kind of confusing because my device is a Cortex-R4F and I hope is configured correctly (please see the attached .zip file).
Trying to isolate the problem I saw that some basic commands under J-Link commander are reporting issues:
1) "reset" reports: "WARNING: CPU not halted after Reset, halting using Halt request".
2) "go" reports: "****** Error: CPU is not halted".
Thus I guess I should not blame uVision as the basic J-Link communication is not working properly. I tried to adjust the communication speed but I was not successful.
I don't know where exactly shall I check deeper...has anyone an idea what could it be? Any suggestion is welcome.
Thanks,
Mihai
