<robogoat>
I, too, have an orange pi pc, and I would like to boot the thing over usb-otg via fel.
<robogoat>
There is no switch I can see to enter fel mode,
<robogoat>
but if no sd card is present, it automatically does, which is fine with me.
<robogoat>
If I extract the boot0.bin from a working image as described in http://linux-sunxi.org/FEL/USBBoot#Testing , I can re-insert the microsd card and use `fel spl boot0.bin` to boot the system.
<robogoat>
However, I would like to get to load u-boot as well with fel, but that doesn't seem to work. Does anybody have hints as to whether this is possible?

hello
<BorgCuba>
Why does "(cd /home/jan/devel/rk30xx/radxalt/buildroot-2014.05/output/build/glmark2-6b500e4fed2dd7f59edf6a68d907c3eb46356aac; ./waf configure [--enable-glesv2 --prefix=/usr --with-flavors=fb-glesv2 ] )" give "No function [--enable-glesv2 defined in /home/jan/devel/rk30xx/radxalt/buildroot-2014.05/output/build/glmark2-6b500e4fed2dd7f59edf6a68d907c3eb46356aac/wscript"?
<BorgCuba>
I think I have it
<plaes>
um.. wrong channel?
<BorgCuba>
plaes, I cloned this from a git owned by ssvb ...
<BorgCuba>
and I want to use this to test the sunxi-mali drivers
<BorgCuba>
but I found a solution, the [ ] braces were a problem
<plaes>
yeah, rk30xx is rockchip
<BorgCuba>
indeed :-)
<BorgCuba>
when I receive my 15$ boards I will get back to sunxi
<ssvb>
that's a rather low score from x11 drivers which don't implement zero-copy
<BorgCuba>
Yes, and what I get is even lower (39)
<ssvb>
the glmark2-es2 score on Allwinner-A10 with 800x600 window should be around 100-150 depending on the DRAM clock speed (see https://github.com/ssvb/xf86-video-fbturbo readme)
<BorgCuba>
btw, I modified wscript to recognize libpng 1.6, but I dont think that this should cause any speed problems
<ssvb>
it is probably a good idea to check mali clock speed and dram clock speed on your rockchip hardware
<BorgCuba>
ssvb, whats the clock speed on the A10? Is it SP/MP1
<BorgCuba>
actually I remember doing all this for a13 and it was way faster
<BorgCuba>
I will check
<ssvb>
Mali is clocked at 320MHz on Allwinner A10, and DRAM is clocked between 360MHz and 480MHz depending on the board type
<ssvb>
also the dram bus width is either 16-bit or 32-bit on Allwinner A10/A20 devices, 32-bit is naturally faster
<BorgCuba>
[ 3.144361] ddrfreq: change freq to 396 MHz when normal
<ssvb>
BorgCuba: it probably makes sense to check the mali clock setting code in the rockchip kernel and try to identify how many MHz do you actually get
<BorgCuba>
I think its 266? (int mali_gpu_clk = 266;)
<BorgCuba>
@ 1.05V
avph has joined #linux-sunxi
<BorgCuba>
and there is an overclock option 400MHz @ 1.275V
<BorgCuba>
there is a section with glmark2 output, it states a score of 108 (with 600MHz module)
<BorgCuba>
but I guess that for x11
<BorgCuba>
I think I could ask naobsd from linux-rockchip if he joins on #linux-rockchip
<BorgCuba>
a general question: On http://radxa.com/Rock/specifications it says DDR3@800MHz in the kernel log it says 396MHz. Is this (modulo a few MHz) equivalent due to the double data rate?

BorgCuba: yes, there is a bit of confusion about the DRAM clock speed, 400MHz is equivalent to 800MT/s for double data rate memory
IgorPecovnik has joined #linux-sunxi
<ssvb>
BorgCuba: and then you multiply this number by the bus width in order to get the peak theoretical memory bandwidth
<ssvb>
BorgCuba: I have also just ordered this 15$ orange pi board from aliexpress :)

ssvb, I ordered 2 over a month ago and they havent arrived yet

let me check again...

ssvb, whats the state of the H3 kernel?
