Re: RE: OpenELEC Testbuilds for RaspberryPi (Kodi 15.0) - Milhouse - 2015-02-05 (2015-02-04, 19:22)PeaceMkr Wrote: @ Milhouse could you please have a look at this and maybe add these overlays to your next testbuilds? As far as I'm aware, my builds already contain the overlays - let me know if not. OpenELEC 5.0.1 is missing the overlays (should be fixed in their next official release). RE: OpenELEC Testbuilds for RaspberryPi (Kodi 15.0) - Milhouse - 2015-02-05 New OpenELEC I****** build #0204: RPi / RPi2 (Supercedes previous build) Code: # uname -a Based on tip of OpenELEC master (dc87b242, changelog) and tip of XBMC master (3817f094, changelog) with the following modifications:

P.s Some notes about the experimental splash video. It doesn't work fine for me: during boot up there is a cut in the final part of animation - you remember? Ok, I've found that the problem is related to core overclocking. Take a look at these scenarios: 1 - arm_freq=950 over_voltage=6 force_turbo = 0 # core_freq at default Splash animation works fine. 2 - arm_freq=950 core_freq=275 over_voltage=6 force_turbo = 0 The splash animation is not completed. This behavior only occurs at boot time: if I do `systemctl stop kodi; systemctl start kodi` all works fine. No differences with 'force_turbo=1' and lowering the 'arm_freq'. So, the problem is: i can't touch core_freq. Note that my model B runs stable at 950/500 - no crash, hangs, etc. This is my `cat /proc/cmdline`: Code: root=/dev/ram0 rdinit=/init BOOT_IMAGE=/kernel.img usbcore.autosuspend=-1 dma.dmachans=0x7f35 bcm2708_fb.fbwidth=1824 bcm2708_fb.fbheight=984 bcm2708.boardrev=0x100000e bcm2708.serial=0xabbce687 smsc95xx.macaddr=B8:27:EB:BC:E6:87 bcm2708_fb.fbswap=1 sdhci-bcm2708.emmc_clock_freq=250000000 vc_mem.mem_base=0x1ec00000 vc_mem.mem_size=0x20000000 boot=LABEL=SYSTEM disk=LABEL=Storage bcm2708.bcm2835_mmc=1 quiet ssh smsc95xx.turbo_mode=N That's all. Thanks for watching and, again, sorry for my bad 'gøøgled' English .

Once the upgrade is complete, the system will reboot to a rainbow boot screen (as you're now booting the ARMv7 kernel). Shutdown (pull the power) and transfer the SD card into your Pi2, which will boot normally. Thank you for posting that, as I've no joy with the (correct, 501) Pi2 image so far, not getting beyond the 4 colour screen. However, I suggest if anyone finds this update method doesn't progress beyond the initial rainbow, check the existing overclock settings in config.txt, & edit or remove them, otherwise the result may be ARM register dumps for one or more cores, & frame pointer errors, etc. (I edited cmdline.txt to remove "quiet" so I could see boot progress) It's working fine now thanks.

What about core_freq=500, as 275 is a bit of an unusual core overclock (I believe it prefers to work in multiples of some value). Also, don't forget you may need to bump over_voltage_sdram when overclocking, particularly when increasing core frequency which may end up driving the SDRAM a bit harder (at least on the Pi1, possibly not so much on the Pi2).

Thanks, yes, it's worth noting that a Pi1 overclock isn't guaranteed to work on a Pi2 (and vice versa). I'll mention that in the first post where I've added a migration section.

Quote:What about core_freq=500, as 275 is a bit of an unusual core overclock (I believe it prefers to work in multiples of some value). Any suggestions about the initial value for core_freq? For example, there is no difference at 280.

I was a bit worried actually about any consequences of the rather higher overvolt settings for core & sdram, than those suggested for Pi2! However, Raspbian stills boots & appears to work fine, as well as Kodi. It's reassuring, because, for example, as a Raspbian SD image (made for Pi2) works fine in B, B+, & of course, Pi2, it's easy to inadvertently insert a SD card with inappropriate overvolt settings into any RPi. If kodi eventually has dual Arch kernels, the same scenario would apply. I see you've already updated Post 1; a very comprehensive post, thanks.

For example, there is no difference at 280. Not sure what you mean by "initial" value - the default value is 250. For Pi1, these are the recommended overclocks: Code: None: 700MHz ARM, 250MHz core, 400MHz SDRAM, 0 overvolt This thread is probably more appropriate for this kind of discussion.
