| **WARNING** : Early march 2023, a kernel change introduced a regression, causing mtd detection to fail. Hence the device stops after a couple of seconds. This affects several branches: 21.02 snapshot (unidentified release), 22.03 snapshot since r20071 (kernel 5.10.168+), master snapshot since r22302 (kernel 5.15.93+). | [[http://example.com|External Link]] |
