PMU FW from commit 649a2ab sometimes loses samples and sends some samples twice. The bug is related to faulty buffer handling when using asynchronous USB transfers. Updated: Not present in any released version.

When distributing code of a hardware function amongst multiple source files, in order to preserve clarity of the project source, the sds++ needs to knwo about these files by adding them with -files flag. In the project.sdx file these files are mentioned in <hls_files> tag.

The analysis tool should have an export feature for measurements.

Currently there is no information on the interfaces at the input variables of the SdSoC Project. Hence building a standard mult and add design and running autoDPR throws an error. It will be very helpful if a standard SdSoC design can also be uploaded on which this tool works.
Thanks!

When the Zynq ultrascale boots, the JTAG chain is not configured and the ARM DAP is not available. The PMU does not correctly handle this and requires the JTAG chain to be already set up. The analysis tool uses the XSCT tool to setup the JTAG chain and is therefore not affected by the bug.

Hi,

I am trying to install the tool on UBUNTU 18.04. Running make gives me a few warnings as:

Should I get worried about the warnings? Any suggestion?

Hi, I am having issues building the analysis tool for Ubuntu 16.04. I'm not sure what the issue is I followed the instructions for building it manually.

When trying to make bin for a project in which the hw fucntion is distributed over mutliple src files following error occurs:

Hi,

Does STHEM work with Xilinx SDx IDE 2018.03? I am asking this because when running 'analysis_tool', it gives me 'SDSoC not found, or unsupported version'.

Thanks

The PMU will sometimes incorrectly assert JTAG TRST pin, which may result in faulty JTAG communication with the target board.

This bug applies to PMU PCBs V2.0 V2.1 and V2.2, when connected to a target board that has the JTAG TRST pin connected. The TULIPP EMC2DP board is not affected.

To fix this bug, resistor R42 must be removed from the board, and the FPGA flash must be updated with a bitfile that inculdes the fix in git commit 4da98e2. V1.5 and up works.

When using analysis utility via console on a system without an x-server, QT is complaining about a missing desktop and denies execution.

qt.qpa.screen: QXcbConnection: Could not connect to display :0
Could not connect to any X display.

Open STHEM, close project if one is open, open Settings, close Settings will result in a crash.

If the program being profiled is very short, so that it exits before the PMU has done a single sample, the PMU hangs.

The PMU does not enter sample mode when profiling Zynq chips. The reason is due to unimplemented coreHalted() function in release V1.0.

Click and drag the mouse cursor in the profile graph over the y-axis makes the analysis tool unresponsive (completely freezing). Force quit (kill) is required.

In tab profile graph, make a single short click anywhere on the graph. This shifts the whole graph with a zero width to the right side of the screen.

It is not possible to recover from this state without a restart of sthem.

When using Qt 5.12. the profiler crashes when using the sql database.
Error: QSqlQuery::exec: database not open

Reproduce:

1. Build and execute with Qt5.12.
2. Run profiler.
