02:16 <naobsd> ah, pull req for 4.1 was out...

06:29 <Tony_> ah

06:36 <rperier> hi all

06:54 <Tony_> rperier, hi.

15:12 <rperier> mmind00: with kgdb, do you use jtag sometimes on rockchip ? I mean, when you port a new SoC for example... if you get a crash before kgdb is initialized.. it is horrible to debug without a jtag, no ?

15:13 <mmind00> rperier: I haven't used kgdb a lot at all ... and also haven't used jtag on Rockchip boards yet

15:14 <mmind00> rperier: in the beginning I was working with a tablet device of course (without jtag etc) ... but also didn't experience issues which would require it

15:15 <rperier> really ? how to you proceed when you get critical bugs like kernel freezes or hangs during SoC inializations ? (except bisect I mean)

15:15 <rperier> initializations*

15:17 <rperier> that's just for personnal use, nothing more I try to improve myself on this part :)

15:17 <mmind00> rperier: never had any of those ... the biggest unknown was the mmu-thing on the rk3288, but otherwise I didn't have any early freezes or so ... every other early problem came with a nice printout what was wrong ;-)

15:17 <rperier> most of the time, I use kernel backtrace with addr2line or gdb , kgdb is useful but boring to use... there are a tons of technics apparently...

15:18 <rperier> so you was lucky :)

15:18 <mmind00> generally the rockchip loaders bring up most of everything, so you can only shoot yourself in the foot by turning stuff off prematurely :-)

15:19 <rperier> I see

20:41 <cheetahw26> I have a rikomagic 802IV and I was curious if there is anyway to backup the current firmware?

23:21 <cheetahw26> Looks like I can boot from sd card first, then run like a disk image?
