Failure in generating xczu7ev.bba #68

Open burntfalafel opened 1 year ago

burntfalafel commented 1 year ago

Hi, I am using the latest xilinx-upstream branch to run the ZCU104 blinky.sh example. I generate the Makefile successfully and make runs correctly generating me the 4 "binaries" (rapidwright_json2dcp, rapidwright_bbaexport, bbasm, nextpnr-xilinx).

However when I run: java -jar rapidwright_bbaexport.jar xczu7ev-ffvc1156-2-e xilinx/constids.inc xilinx/xczu7ev.bba, I get the following error: 

Exception in thread "main" java.lang.NoClassDefFoundError: com/xilinx/rapidwright/device/IOBankType

If I were to see what was generated by the CMake/Make the error is correctly raised (i.e. No IOBankType generated): image But RapidWright has generated IOBankType class in it's build folder / jar file: image

I have attached the command and the logfile I used below. But it's the exact same to what is in the README.

export RAPIDWRIGHT_PATH=<path-to-RW>
cmake -DARCH=xilinx -DRAPIDWRIGHT_PATH=<path-to-RW> -DGSON_PATH=./gson-2.8.5.jar .
make

CMake.log Make.log

(PS - I understand it's a work in progress, but this will help me greatly if you know what's going on...Thanks :))
