Hi, I remember that there has been an issue, only seen on Cortex-A7/A15, like the Allwinner A20.
The fix for that issue is somewhere here[0]. Try this[1] kernel and have a look if it has the same issue or not. I do not have an A20, so I can’t test it, sorry. But I’ll probably buy this[2][3] one once it’s available. \Patrick [0] https://github.com/bitrig/bitrig/commit/f1932308435a4b2c3daf0e880dc0adc829f5803d [1] https://www.blueri.se/bitrig/armv7/20140925/bsd.rd.SUNXI.umg [2] http://www.allnet.de/at/allnet-brand/produkte/neuheiten/p/banana-pi-router-board/ [3] http://www.sinovoip.com.cn/ecp_view.asp?id=554 > Am 02.10.2014 um 20:56 schrieb SASANO Takayoshi <u...@mx5.nisiq.net>: > > Hello, > > I tried bsd.rd.SUNXI.umg snapshot on Banana Pi, cheap Allwinner A20 > board like Raspberry Pi (see http://www.lemaker.org/). > > It booted but something wrong.
