Semihosting works perfectly using Ozone and my test results are written to the terminal window. But since we are evaluating ways to perform automated software test I need to be able to run the tests in a batch mode such as using JRun. Trying JRun, no terminal messages are shown and it appears to hang indefinitely. Is it possible to use semihosting with JRun instead of Ozone? Or perhaps J-Link? jrun -device "MK66FN2M0XXX18" --semihost mytest.elf J-Run compiled Sep 14 2021 16:09:55 (c) 2018-2021 S…

I've been using Ozone with J-Link for trace. I had trouble several months ago but the latest versions seem to work well. But we are interested in using the profiling features of J-Trace. It sounds like the answer is, we can't because Atmel/Microchip didn't plumb the required signals to the pins. Thanks for the replies.

We are considering purchasing a J-Trace for profiling features not available on our J-Link devices. Using IAR. I'm trying to find which pins need to be routed to a connector and what connector that is. Also, if the J-Trace is compatible with our device. We use an SAMA5D27 Arm processor. We have a JTAG connector but presumably ETM requires more pins and another connector(?). Will the J-Trace work with our processor (support profiling features)? What connector is needed and what is the pinout rega…

Thanks. So the "caching" is in Ozone memory on the PC rather than the J-Link, so there no problem with a MB or two of code?
-
Thanks, that was very helpful! The trace is working now. Since I don't fully understand what the ReadIntoTraceCache command is doing, can you provide details? Is there a limitation to the number of bytes cached? For example, I have a fairly large app loaded into DDRAM and would like to be able to trace all of it. It's well over a MB.

The instruction trace shows mostly ?'s.

I'm using Ozone for instruction trace with a ATSAMA5D27. Initially a bootloader is run from SRAM and trace and breakpoints work well at that point. But as soon as execution is started in DRAM the instruction trace listing is mostly 0xFFs. Using J-Link Ultra+ with Trace Buffer setting. Perhaps there are settings related to memory access that need to be tweaked when executing in DRAM. Thanks

Trying to run the example in Embedded Studio (release 4.18) results in an error message: Failed to download application. Generic error. Please check J-Link and target connection. Ozone is V2.62f. When I select "Start Debugging" "Download and Reset Program" I get the following in the console window. (Thanks.) (BTW I used jlink.exe to connect to the XPlained board and it seems to be OK.) Debug.Stop(); J-Link: disconnected from target device Debug.SetConnectMode (CM_DOWNLOAD_RESET); Debug.Start(); …

I downloaded 6.34g, updated the firmware, but no help. The connector I use is an Atmel part.

If I open J7, J-Link can see the SOM1 through the USB connection. I can program the board but debugging is limited, and I'd prefer to get the JTAG ICE working. With J7 closed, the emulator connected to JTAG can't see the board, as shown above. Should I try another J-Link emulator, as perhaps this one is faulty? (I received a new SOM1 eval board, and it behaves identically.) Any help would be appreciated.

Thank you for your response. SEGGER J-Link Commander V6.32f (Compiled Jun 12 2018 14:47:13) DLL version V6.32f, compiled Jun 12 2018 14:46:40 When I press the reset button, I see RomBOOT on the serial port, so I think J-Link OB (USB J10) works. Yes, I have a jumper closing J7. I have ordered another board, perhaps this one is defective. What is pin 15 (RESET)?

Having trouble with J-Link communicating with the SAMA5D27 on the eval board, ATSAMA5D27-SOM1-EK1.

Using IAR IDE and a J-Link Base ICE with SAMA5D2 on XPlained eval board. Stepping through the code, the IDE locks up. When I break, the code is execting the Undefined Insruction exception handler. Looking at the LR, the instruction at that address disassembles, so I presume it is not the problem. Stack pointer looks good. Any suggestion how to diagnose this condition?
