I encountered the following issue while working on RVfpgaSOC Lab5 when I ran the command make -f tensorflow/lite/micro/tools/make/Makefile TARGET=zephyr_swervolf BUILD_TYPE=debug hello_world_bin as instructed in the guide:
Build flags:
make VERBOSE=1 [targets] verbose build
cmake -DW=n Enable extra gcc checks, n=1,2,3 where
1: warnings which may be relevant and do not occur too often
2: warnings which occur quite often but may still be relevant
3: more obscure warnings, can most likely be ignored
Multiple levels can be combined with W=12 or W=123

My environment variables are set correctly.Could someone help me identify what went wrong here?
Hi,
Did you check out the exact versions specified in the document?
For everything, swervolf, zephyr SDK, tensorflow etc
I have now resolved the above issue, mainly because SweRVolf has been renamed to VeeRwolf, which affected Lab 3, 4, and 5 in the RVfpgaSoC series. This means that in Lab 3, the command fusesoc library add swervolf https://github.com/chipsalliance/Cores-SweRVolf used to add the repository should now reflect the file swervolf.core in the $WORKSPACE/fusesoc_libraries/swervolf path being renamed to veerwolf.core. To run simulation builds using fusesoc, the command in the experiment guide fusesoc run --target=sim swervolf should be changed to fusesoc run --target=sim veerwolf. Similarly, in experiment 5, the board target swervolf_nexys specified in the Makefile.inc file should be changed to veerwolf_nexys. This resolves the issues mentioned above.
Following this, when I run the command make -f tensorflow/lite/micro/tools/make/Makefile TARGET=zephyr_swervolf BUILD_TYPE=debug hello_world_bin -j 16, I encounter an error indicating that the veerwolf_nexys board target requires Zephyr SDK version 0.13.1 or above, whereas the experiment guide provides Zephyr SDK version 0.12.4, which is a mismatch. The renaming of SweRVolf to VeeRwolf renders the RVfpgaSoC experiment guide completely outdated.
After downloading Zephyr SDK 0.13.1 myself, the above issues were essentially resolved. However, I encountered a new problem:
(venv-zephyr) plc330@ubuntu:~/RVfpgaSoC/Labs/LabProjects/SweRVolf/tensorflow$ make -f tensorflow/lite/micro/tools/make/Makefile TARGET=zephyr_swervolf BUILD_TYPE=debug hello_world_bin -j 16

[Further build messages...]
I already updated the contents of CMakeLists.txt in the path tensorflow/tensorflow/lite/micro/tools/make/gen/zephyr_swervolf_x86_64_debug/prj/hello_world/cmake/ from:
target_include_directories(app PRIVATE . third_party/gemmlowp third_party/flatbuffers/include third_party/ruy third_party/kissfft /home/plc330/RVfpgaSoC/Labs/LabProjects/SweRVolf/tensorflow /riscv64-zephyr-elf/riscv64-zephyr-elf/include/c++/9.2.0 /riscv64-zephyr-elf/riscv64-zephyr-elf/include /riscv64-zephyr-elf/riscv64-zephyr-elf/include/c++/9.2.0/riscv64-zephyr-elf/rv32i/ilp32 )
to reflect the changes in the new Zephyr SDK 0.13.1:
target_include_directories(app PRIVATE . third_party/gemmlowp third_party/flatbuffers/include third_party/ruy third_party/kissfft /home/plc330/RVfpgaSoC/Labs/LabProjects/SweRVolf/tensorflow /riscv64-zephyr-elf/riscv64-zephyr-elf/include/c++/10.3.0 /riscv64-zephyr-elf/riscv64-zephyr-elf/include /riscv64-zephyr-elf/riscv64-zephyr-elf/include/c++/10.3.0/riscv64-zephyr-elf/rv32im/ilp32 )
But the above error is still encountered.
After downloading Zephyr SDK 0.13.1 myself, the above issues were essentially resolved. However, I encountered a new problem:
Hi @samuelgebsons,
Can you provide more information about the new problem? Something like screenshots, the output of your terminal, etc.
Thanks
Best regards
Dani
