Hi, seems like this fixes it (at least i get over the faulty point see now the DTEX lines): pip3 install jsonschema==4.17.0 seems my previous version was 4.6.0 Requirement already satisfied: jsonschema in /home/frank/.local/lib/python3.10/site-packages (4.6.0) first tried upgrade of this, but this results in 4.19 which is not compatible with dtschema ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts. dtschema 2023.7 requires jsonschema<4.18,>=4.1.2, but you have jsonschema 4.19.0 which is incompatible. so i set the last version told to be compatible regards Frank > On 03/09/2023 13:08, Frank Wunderlich wrote: > > Hi, > > > > i tried to check a binding-file with 6.5 kernelsource and get this error > > > > GNU nano 6.2 dt.log > > LINT Documentation/devicetree/bindings > > CHKDT Documentation/devicetree/bindings/processed-schema.json > > SCHEMA Documentation/devicetree/bindings/processed-schema.json > > Traceback (most recent call last): > > File "/home/frank/.local/bin/dt-mk-schema", line 38, in <module> > > schemas = dtschema.DTValidator(args.schemas).schemas > > File "/home/frank/.local/lib/python3.10/site-packages/dtschema/validator.py", line 354, in __init__ > > self.schemas = process_schemas(schema_files) > > File "/home/frank/.local/lib/python3.10/site-packages/dtschema/validator.py", line 271, in process_schemas > > sch = process_schema(os.path.abspath(filename)) > > File "/home/frank/.local/lib/python3.10/site-packages/dtschema/validator.py", line 248, in process_schema > > dtsch.is_valid() > > File "/home/frank/.local/lib/python3.10/site-packages/dtschema/schema.py", line 145, in is_valid > > for error in self.DtValidator(self.DtValidator.META_SCHEMA).iter_errors(self): > > File "/home/frank/.local/lib/python3.10/site-packages/jsonschema/validators.py", line 242, in iter_errors > > for error in errors: > > File "/home/frank/.local/lib/python3.10/site-packages/jsonschema/_validators.py", line 362, in allOf > > yield from validator.descend(instance, subschema, schema_path=index) > > File "/home/frank/.local/lib/python3.10/site-packages/jsonschema/validators.py", line 258, in descend > > for error in self.evolve(schema=schema).iter_errors(instance): > > > > block from line 242-258 repeats many times (~2000 lines in log) > > > > File "/home/frank/.local/lib/python3.10/site-packages/jsonschema/validators.py", line 242, in iter_errors > > for error in errors: > > File "/home/frank/.local/lib/python3.10/site-packages/jsonschema/_legacy_validators.py", line 216, in recursiveRef > > lookup_url, next_target = validator.resolver.resolve(each) > > File "/home/frank/.local/lib/python3.10/site-packages/jsonschema/validators.py", line 835, in resolve > > url = self._urljoin_cache(self.resolution_scope, ref).rstrip("/") > > RecursionError: maximum recursion depth exceeded in comparison > > > > make[2]: *** [Documentation/devicetree/bindings/Makefile:68: Documentation/devicetree/bindings/processed-schema.json] Error 1 > > make[2]: *** Deleting file 'Documentation/devicetree/bindings/processed-schema.json' > > make[1]: *** [/media/data_nvme/git/kernel/BPI-R2-4.14/Makefile:1516: dt_binding_check] Error 2 > > make: *** [Makefile:234: __sub-make] Error 2 > > > > my command is (after importing defconfig, also tried a clean before): > > > > ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make dt_binding_check > > > > already did an update of dtschema with "pip3 install dtschema --upgrade" and also an uninstall/install of this python-package > > > > $ pip3 show dtschema > > Name: dtschema > > Version: 2023.7 > > Summary: DeviceTree validation schema and tools > > Home-page: https://github.com/devicetree-org/dt-schema > > Author: Rob Herring > > Author-email: robh@xxxxxxxxxx > > License: BSD > > Location: /home/frank/.local/lib/python3.10/site-packages > > Requires: jsonschema, pylibfdt, rfc3987, ruamel.yaml > > Required-by:
