12:24 <npl> hello, I got some problems running a firefly rk3288 with mainline u-boot. Or rather, u-boot works but can start any linux kernel, it just hangs at "Starting kernel ..."

12:26 <npl> Tried current u-boot with CONFIG_EFI_LOADER disabled, and an older one (2016.1). Tried a self-compiled kernel, and one extracted from Firefly`s Ubuntu Image

12:27 <npl> Don`t find much info around the net for using Rockhip without the "rockchipped" u-boot

12:27 <npl> some known to work configurations would be nice, don`t have an JTag Adapter to dig deeper

15:18 <npl> One step further: "Uncompressing Linux... done, booting the kernel."

15:34 <mmind00> npl: try enabling the debug uart + earlyprintk output, as this will hopefully show you more early boot output and maybe even what fails

15:36 <mmind00> npl: these options: http://pastebin.com/mHaskQXg

15:51 <npl> sorry, been running with that for a while. Doesnt do alot, normally I would have alot more output before the ramdisk gets started?

15:52 <npl> But to be honest, I tried so much stuff in-between, I dont exactly know why it now atleast decompresses. (maybe this fix helped: http://lists.denx.de/pipermail/u-boot/2016-July/261663.html)

15:54 <npl> If you`d start now, what sources would you recommend, there are multiple branches for u-boot (eg. with net), and an almost infinite amount of kernels?

15:56 <npl> I am currently on denx`master branch for u-boot and kernerl 4.8rc1 with this config as base: https://bitbucket.org/T-Firefly/firefly-rk3288-kernel/src/e5d1ccebdd1f414c691589afa61197e9757702be/arch/arm/configs/firefly-rk3288_defconfig?at=master

16:51 <mmind00> npl: I'm a bad advisor in this regard, as I'm not having any specific project of my own and just try to improve the whole experience, so I'm just running mainline rc kernel for all my stuff

16:52 <mmind00> as for uboot, I've actually not tried the mainline uboot on my rk3288 boards, but could run mainline uboot on a rk3036 board just fine

17:01 <npl> So, in other words mainline 4.8rc should support rk3288 mostly. Can you give me some hint to where you can get the missing defconfigs, or are you configuring everything by hand?

17:02 <npl> Finding information about these boards and piecing everything together is painfull

17:03 <npl> Either you dont find anything or multiple sources, completely out of sync with everything else =)

18:12 <npl> crap crap crap. Dont use ccache for compiling the kernel. Saving half an hour compiling > searching weird stuff for 2 days

18:14 <mmind00> npl: :-) is your kernel working now?

18:14 <npl> not working, but failing *with text* =)

18:15 <npl> ends with those lines:

18:15 <npl> [ 1.945001] hctosys: unable to open rtc device (rtc0) [ 1.965453] dovdd_1v8: disabling [ 1.968979] vcc_sd: disabling [ 1.972170] vcc_flash: disabling

20:31 <npl> hmm, cant get this to run. No idea why

20:51 <gllima> Anyone can help me with questions about Firefly RK3288 Reload development?

20:59 <npl> I likely cant, but just ask and wait
