The first thing I tried with this was according to the user documentation: ./bareboxtlv-generator.py --input-data data-example.yaml schema-example.yaml tlv.bin And fed that into the barebox tlv command. I ended up with an empty node because the magic doesn't match. Can we change the magic to TLV_MAGIC_BAREBOX_V1 in the example and only add things here that are supposed to be generic? That would make the example more useful as a starting point. > + > +tags: > + factory-timestamp: > + tag: 0x0003 > + format: "decimal" > + length: 8 > + example: 1636451762 > + > + modification: > + tag: 0x0005 > + format: decimal > + length: 1 > + example: 42 > + purpose: "0: Device unmodified; 1: Device has undocumented modifications" 0 is unmodified, 1 is modified and 42 is what? ;) Sascha -- Pengutronix e.K. | | Steuerwalder Str. 21 | http://www.pengutronix.de/ | 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 |
