Quote from: exxos on February 05, 2014, 04:30:46 pmHi There,I have looked into detail the boot loading via UART for this kernel (Patwood A20 3.4.75+) and I have noticed some points:This note could be rephrased?<5>Linux version 3.4.75-sun7i+ (email@example.com) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) #37 SMP PREEMPT Tue Dec 31 00:22:38 EST 2013

QuoteQuestion ? Does the pwm_sunxi need to be loaded as module or is it embedded to this kernel?[info] Loading kernel module pwm_sunxi.modprobe: FATAL: Module pwm_sunxi not found.
# zgrep PWM /proc/config# CONFIG_ATMEL_PWM is not set# CONFIG_SUNXI_PWM is not set

QuoteOtherwise, this kernel configuration seems to be fine. So, I would thank Patwood very much for his great job. It saved me lot's of time! Thant you, thank you!Cheers,exxos.

HW video decode is working, and libhybris is integrated: http://linux-sunxi.org/CedarX/libve. This solves issues with weighted P-frame prediction in files like the Sintel movie trailer described here: http://linux-sunxi.org/CedarXVideoRenderingChart.http://dl.cubieforums.com/patwood/Cubiuntu0.6.5b-a20.img.xzsize: 901406416, md5: 994133991092ca09a1d0e9e44ed31353As before passwords are root/root linaro/linaro.No, xbmc isn't in this version.
