Problem when emulating on nexys #323

Open Clay-Cui opened 9 months ago

Clay-Cui commented 9 months ago

Hi, I followed the readme file and try to use make nexys-emul to generate the bitfile for the nexys board. However, I keep getting this error ERROR: Setup failed : Cannot find emulation/core-v-mcu-nexys/rtl/core_v_mcu_nexys.v in . cp ./build/openhwgroup.org_systems_core-v-mcu_0/nexys-a7-100t-vivado/openhwgroup.org_systems_core-v-mcu_0.runs/impl_1/core_v_mcu_nexys.bit emulation/core_v_mcu_nexys.bit cp: cannot stat './build/openhwgroup.org_systems_core-v-mcu_0/nexys-a7-100t-vivado/openhwgroup.org_systems_core-v-mcu_0.runs/impl_1/core_v_mcu_nexys.bit': No such file or directory Makefile:122: recipe for target 'nexys-emul' failed

I looked into ./build/openhwgroup.org_systems_core-v-mcu_0/nexys-a7-100t-vivado/ there is only a subfolder called src, no folder is called run. How should I fix this? And in the readme file, I don't quite get how to install latest board-parts with the core_v_nexys_200122.bit?

Thank you in advance for any help!

I see an oversight on the Makefile when building the nexys target, It creates the top level file with an incorrect name "emulation/core-v-mcu-nexys/rtl/core_v_mcu_util.v" instead of "emulation/core-v-mcu-nexys/rtl/core_v_mcu_nexys.v" A quick solution would be to cp emulation/core-v-mcu-nexys/rtl/core_v_mcu_util.v emulation/core-v-mcu-nexys/rtl/core_v_mcu_nexys.v make nexys-emul

Thank you very much for your reply. I copied the file and found another error. Traceback (most recent call last): assert loader is not None, "A loader was not found for the package." AssertionError: A loader was not found for the package.

Seems like an error regarding to the jinja2? I didn't change anything in the source code... Or does my environment is wrongly configured?

Thank you very much!

Edit: I think I found out the problem. It's the jinja version. I'm using Ubuntu18.04 which comes with python 3.6. Jinja2 droped python 3.6 support since jinja2 3.1. So I the latest i can get is install jinja2 3.0.3. And it gave me such error. If i use python version greater than 3.6, install the latest jinja2, the error is gone. And I'm waiting for the vivado to finish. Thank you for your help!
