OK, can you please use something like https://source.denx.de/u-boot/u-boot-extras/-/blob/master/contrib/trini/u-b= oot-size-test.sh?ref_type=3Dheads for the whole board? > Change times let users immediately spot which files were modified most > recently (kernel images, device trees). >=20 > If a device stops booting, seeing a file=E2=80=99s change date helps dete= rmine > whether a recent change could be the cause. Yes, that is useful and more user friendly than hashing a file. But I do worry about global size growth. --=20 Tom --6yiov/VBg8GGtcD+ Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQTzzqh0PWDgGS+bTHor4qD1Cr/kCgUCagxr5QAKCRAr4qD1Cr/k CvOTAQDvzng/P1d539wOJvnf7WoIM+Lt/y+SFSuc7GiqtRGbDwEAjqkyjbWh6gxj FQKb6J9Iq46vS4YM40o0+NBfCeydcQI= =rC3d -----END PGP SIGNATURE----- --6yiov/VBg8GGtcD+--
