naobsd, thanks, then I just need to make sure it works on gstreamer
04:32
<
ayaka >
naobsd, I don't care whether the kernel or u-boot is mainline or not, current goal is not here
04:33
<
ayaka >
but I wish I would use a version of kernel and u-boot is closed to the mainline
04:33
<
ayaka >
I could sumbit my patches into mainline easily

<

ayaka: then mainline u-boot/linux will be better, but
07:23
<
naobsd >
I'm not sure
_reload_ ver. works or it needs some work
07:37
<
ayaka >
naobsd, maybe I just need to modify some part of dts
07:37
<
ayaka >
naobsd, by the way, how to erase the bootloader in emmc?
07:39
<
naobsd >
you can try sd boot by "rkflashtool b 3" before erasing emmc
07:41
<
naobsd >
about erasing, run "dd if=/dev/zero of=/dev/mmcblk0 bs=1M count=1" on firefly will work
07:42
<
ayaka >
so I should boot into emmc first and erase the first 1MBytes of emmc
07:42
<
ayaka >
then try boot from sdcard
07:42
<
naobsd >
it might be possible to erase emmc by PC tool, but sometimes it might not work well
07:42
<
ayaka >
I will have review about the dts first
07:43
<
naobsd >
you can try sd boot before erasing emmc
07:43
<
ayaka >
I am a little a afraid of using usb otg, I broken hardware the last time I use samsung board
07:44
<
naobsd >
ah, well, bs=4M count=1 might be better to erase everything for boot
07:45
<
naobsd >
ah, it will erase serialno too
07:46
<
naobsd >
there is a way to write everything include serialno, but it might be better to make backup of 1st 4MB
07:48
<
naobsd >
anyway, you can try sd boot, 1. enter loader mode, 2. run rkflashtool b 3,
07:49
<
naobsd >
sorry, I'm walking now, later
07:59
<
naobsd >
ah sorry, 4MB might be minimum
07:59
<
naobsd >
1MB may not be enough
07:59
<
naobsd >
I can't calculate for now ;)
08:04
<
ayaka >
anyway I could boot the u-boot from sdcard now
08:05
<
ayaka >
I can't care about size this time, I just erase the first 1MB is enough to make 1st bootloader ignore the emmc right?
08:15
<
naobsd >
probably no, 4MB should be right size
08:16
<
naobsd >
well, I can explain more later, but not now
08:19
<
ayaka >
yes I tried, 1MBytes won't work but 4MBytes would, I am always waiting here

if u-boot binary for original works, you can try mainline linux
08:29
<
naobsd >
u-boot uses very common/core units only, difference between original and reload might be ignored
08:30
<
naobsd >
ayaka: can you access sd card on mainline u-boot?
08:31
<
naobsd >
fat and/or ext fs should be supported in that binary
08:31
<
ayaka >
naobsd, yes, but not using the exactly mainline u-boot, just the forked version
08:32
<
ayaka >
well, I am not plan to write kernel into a filesystem
08:32
<
ayaka >
I just want to write it to raw or it would be loaded slowly
08:32
<
naobsd >
you want tftp?
08:32
<
ayaka >
not just write it to sdcard with some offset
08:33
<
ayaka >
I am not newbie in embeded, but just newbie to rockchip
08:34
<
naobsd >
personally I don't feel fs is so slow
08:35
<
ayaka >
it would be interested to add net supported in u-boot
08:35
<
ayaka >
I tried put the kernel in sdcard in an ext2 partition in exynos4412
08:35
<
naobsd >
hehe, sometimes experienced developer wants too much from u-boot
08:35
<
ayaka >
it would cost me more than 2 seconds to load it into memory then boot it
08:36
<
ayaka >
but if just raw way, it would be done in less 1 second
08:36
<
naobsd >
well, there is patch for network support... it might be in HEAD?
08:37
<
ayaka >
let me have check, I won't just it would difficult, it is just GMAC PHY driver
08:38
<
naobsd >
it's dwc gmac
08:38
<
naobsd >
I don't know about phy on reload
08:38
<
ayaka >
that would be better, dwc IP core have been widely supported in u-boot
08:39
<
ayaka >
samsung also use it in emmc
08:39
<
naobsd >
emmc/sd is dwc too
08:39
<
naobsd >
usb is dwc2
08:43
<
ayaka >
ok, u-boot seems support the dwc gmac
08:45
<
naobsd >
RK platform support is in mainline now?
08:48
<
ayaka >
why not, the dts file is in the mainline for a long time
08:48
<
ayaka >
I choose the firefly just because I saw it in the kernel and u-boot
08:49
<
ayaka >
and the other two board are not sold in taobao
08:50
<
naobsd >
dts in u-boot is from kernel
08:50
<
naobsd >
code is not from kernel
08:51
<
naobsd >
I'm talking about network support
08:52
<
ayaka >
naobsd, I think the support for designware is in u-boot
08:52
<
ayaka >
drivers/net/designware.c the log shows that it is merged in 2015
08:52
<
ayaka >
but I think I need a phy driver
08:53
<
naobsd >
I'm talking about RK platform support
08:53
<
naobsd >
I'm very sure that patch is available long time
08:54
<
naobsd >
but it was not merged at March at least
08:55
<
ayaka >
then I am not sure now
08:56
<
ayaka >
anyway if it is not, I could submit a patch
09:13
<
ayaka >
naobsd, ok, the net is not supported by u-boot
09:16
<
ayaka >
the better news is the phy chip rtl8211 is supported in u-boot, then I only need to add a driver for it

15:35

mmind00, oh, I though you are the author

actually it need some work to work on currently u-boot, fix some compiling error
