I tried to run the PSoC 4 CAN Basic Example Project on my CY8CKIT-046 PSoC 4 L-Series Pioneer Kit.
I can build and download this project but when I run it, nothing expected happen (no signals on the CAN tx output pin, and no communication over the serial port.
Then I started the debugger and now I got the Error: dbg.M0015:
Debugger exited unexpectedly during run. Encountered error (Target disconnected See output window for more information.)
When I activate under Tools, Options, Program/Debug, On Run/Reset, run to: Reset Vector, I can get a bit more informations:
Now the debugger starts without a failure, it stands on void Reset(void) with Step I can get into the function Start_c()
where the memory seems to be initialzed correct.The error dbg.M0015 happen when __libc_init_array(); is called. main() would be the next call after __libc_init_array() but it seems that main() is never reached. I tried all the things which I found on the net like:
.cydwr Programming\Debugging, Debug select to SWD (serial wire debug) and the
Flash security all to Unprotected
I work with PSoC creator Software 220.127.116.111.
The same behavior happen with Windows 10 and Windows Vista.
When I create a short project which write some Informations to the serial port all work fine (serial port writings and debugging).
Has someone make the same experiance with the CAN example?
How can I find a solution for this problem?
Thank you very much for your help.
fortunately I could find the problem.
The CAN Basic example expect an external clock source on P0.
Unfortunately such a clock source isn't available on the board, and P0 is also connected to the CapSense Gesture Pad on the daughter board.
I changed the Direct_Sel from EXTCLK (24MHz) to IMO (24MHz).
Now the example program run and I can debug it.
