Zybo Z7 Pcam 5C Demo - AP transaction error

[Vijay_sr05]

Hello,

I am executing the Zybo Z7 Pcam 5C Demo example program using Vivado 2016.4 and I'm getting an - AP transaction error. 

Error while launching program:  Memory write error at 0x100000. AP transaction timeout

Below is the demo program. Kindly help!

Hi @Vijay_sr05,

I was able to generate a bitstream without and issue in Vivado 2016.4. I then export the hardware incluting the bitstream and launch sdk from Vivado. Once SDK is loaded I import the applications from the SDK folder. I then program the fpga. Next I right click on pcam_vdma_hdmi and run as->launch on Hardware(system debugger). It loaded onto my Zybo-Z7-20 without an issue. I have included some screen shots. The applications are greyed out from my import screen shot since I had already imported the applications to my project.

cheers,

Jon

Hello @jpeyron

Thank for the reply. I am following the exact same steps. When I run as "Launch on hardware (system debugger)", it executes for 99% and then fails. Please see the attached images.

Thanks.

Hi @Vijay_sr05,

 I would exit SDK and delete the pcam-5c.sdk file in the proj folder. Then I would go to the vivado project again and re-export the hardware including the bitstream and launch the sdk from vivado. Then re-import the applications and see if this solves the issue. You are also programming the fpga before running the application as shown in the screen shot below.

thank you,

Jon

Hello @jpeyron

Below is the SDK log, after exporting the sdk and reading the files, I did "launch on h/w" and then programmed the FPGA. This doesn't seem to be right to me, but there is no error. Below is the SDK log. Also I assume this demo program will turn the camera on and display on a HDMI monitor and this doesn't seem to work. I assume once I run, launch on hardware, the camera should turn on and I should see the display on the hdmi monitor? Appreciate any help!

Hi @Vijay_sr05,

To clarify, you are first programming the FPGA and then running the application(run as->launch on hardware(system debugger))?

thank you,

Jon

[Vijay_sr05]

Hi @jpeyron

Yes. That's correct. I'm following the step 5.3 and 5.4 of SDK and the link is below.

Hi @Vijay_sr05,

Is the mode jumper JP5 on the Zybo-Z7-20 set to JTAG? Did you change anything in the zynq processor in the block design in the Vivado 2016.4 project? Are there any errors when you generated a bitstream in vivado? Any errors in the sdk under problem tab? If so can you attach screen shots? Are you able to make a project using the preset board files for the Zybo-Z7-20 in vivado 2016.4?

thank you,

Jon

[Vijay_sr05]

Hi @jpeyron

Thank you so much for your inputs! I was able to fire up the camera. This board is pretty cool. 

There were 2 issues the mode jumper JP5 on the Zybo-Z7-20 was not set to JTAG and second was the project files were open in Vivado 2017 (the IP's were changed by mistake I believe) and then later I got a new copy of the demo and re-ran the whole thing. Appreciate your help. 

Vijay
