Schematic Library Quickstart

So, I'm going through the Schematic Library Getting Started tutorial and I get this error when I get to the point of uploading the example sketch to the papilio via the ZAP IDE.

Before I did the schematic library getting started tutorial, I did the ZAP IDE quickstart, and I was able to compile and upload the same example sketch without issue.

 

Have I missed a crucial step somewhere in the Schematic Library Getting Started Tutorial?

 

Thanks.

Hello,

 

The most likely culprit here is that you might have written the generated bit file to the FPGA instead of SPI Flash. The ZPUino operates with a bootloader and requires that it be loaded into SPI Flash and restarted before it will work. If you are loading directly to the FPGA then the ZPUino soft processsor will not be operating and will not respond to the ZAP IDE.

 

Can you verify that you loaded your generated bit file to SPI Flash?

 

Thanks,
Jack.

Hey,

 

The SPI Flash should be erased and rewritten every time, can you verify that you are seeing multiple steps. It should erase, verify erase, program, and verify program. If you are not seeing all of those steps then change to expert mode in preferences and make sure all the steps are selected.

All right!  I put the papilio loader in expert mode and then closed the loader and reopened it in order to set the changes permanently.  I loaded the bit file and made sure that it was set to SPI Flash.  It seems to have worked!

 

Thanks a lot for the help, Jack.

 

One more question...I do have an Arduino and I already had the IDE installed.  Can I use the ZAP IDE with an Arduino like I normally use my Arduino IDE?  In other words, will the ZAP allow me to program my Arduino AND the ZPUino, or will it only work with the ZPUino?  I'm essentially looking to see if I can get rid of the Arduino IDE or if I need to keep it if I plan to continue to use my Arduino Mega.

 

Thanks again.
