Description Christoph Biedl 2015-11-05 07:41:39 UTC

The summary basically says it all: On two different Allwinner A20
based models (Cubietruck and BananaPi), loading the new "security
system" fail. According to http://sunxi.montjoie.ovh/, these systems
are supposed to be supported.

dmesg log:

| sun4i-ss 1c15000.crypto-engine: no reset control found
| sun4i-ss 1c15000.crypto-engine: Die ID 0
| sun4i-ss 1c15000.crypto-engine: Fail to register md5
| sun4i-ss: probe of 1c15000.crypto-engine failed with error -22

This happened both to me and a friend who uses completely different
kernel options. Therefore I suspect there's either still a bug in the
code, or it relies on a certain kernel configuration variable without
enforcing it.

Sorry if this is a bit vague, I don't know better for myself.
