I'll use tar and/or resize2fs
<naobsd>
if I have to make 1000 copies, I'll prepare some automate system
<naobsd>
probably few simple script will be enough

if someone decided to use open/free software for his project, he need to find out solution himself. consulting service is not included in free/open software. many cases necessary tools/technologies are already available and open.
<naobsd>
sometimes it may not be easy
<naobsd>
but if you decided not to hire consultant and/or engineer, you have responsibility...
<naobsd>
many many many people expect too much from open/free project

Is there a way to get the bootloader version from Android for standard users?
<naobsd>
"I'm waiting when it's ready"
<naobsd>
"from Android for standard users" ?
<cnxsoft>
I'm checking Linuxium procedure, about SD card boot, and he says to check the version is 'RK3288Loader_uboot_V2.17.02.bin'.
<cnxsoft>
I can do that with a serial console, but it's not so conenient
<naobsd>
if "standard users" have firmware image for their device and can flash it with flashing tool, tool will show version
<cnxsoft>
so I wonder if there's another way. maybe not in Android directly.
<cnxsoft>
Yes that's true. but if you don't have th firmware, will these tool read the bootloader version?
<cnxsoft>
I can't find option for that
<naobsd>
I'm not sure all tool show version, but some tools show version when you opened firmware file
<naobsd>
like file path, time stamp, and version
<cnxsoft>
OK., I'll just say to load the fimrware in AndroidTool to check the version...
<naobsd>
but it's not "currently running" firmware version
<naobsd>
if it's not same firmware on device, you have to flash it
<naobsd>
alternatively,
<naobsd>
dmesg from running device will have bootloader version in kernel command line
<naobsd>
I don't know everyone can do it
<naobsd>
and
<naobsd>
there is a command to get bootloader version from device via OTG in loader mode
<naobsd>
I think rkflashtool support it
<cnxsoft>
Thanks.
<naobsd>
but
<naobsd>
if you just want to know "flashed loader support SD boot or not"
<naobsd>
there is very easy way
<naobsd>
just try it
<cnxsoft>
:)
<naobsd>
flash tool which supports only individual image may not show version
FreezingCold has joined #linux-rockchip
<naobsd>
because it's possible to flash individual images except bootloader...
<cnxsoft>
Ah yes, like RKFlashKit

cnxsoft, other way to get version of loader is /proc/cmdline.
<Tony__>
cnxsoft, you can run "cat /proc/cmdline".
<naobsd>

ah I (mis)understood usb2uart function... it can be used only if uart2 tx/rx is connected to otg dp/dm :(
<rperier>
mmind00: it would be interesting to use the devicetree overlay for some of our boards once it will get merged. Typically for the radxa rock pro, which will be share 90% of its hardware components with the radxa rock. (we might use a cloned dts at the beginning and switch to a devicetree overlay once it is ready)
<naobsd>
devicetree overlay? interesting :)
<naobsd>
I'm thinking to make 2 or 3 dts for each board ;)
<rperier>
yes, the devicetree maintainer are working on a dynamic devicetree. devicetree resolver has been merged in 3.18 for example. The idea is to be able to modify a property on the fly while the kernel is running or to add a devicetree component on the top of a another one while the kernel is running
<karlp>
overlay is still pretty much in flux isn't it?
<rperier>
it would be very interesting for boards which dynamic hw topology or with boards with different extensions boards or which share hw components
<rperier>
s/which dynamic/with dynamic/
<mmind00>
rperier: hmm, personally I'd limit overlays to actual user-defined things (like which function ends up on the pin headers) ... the board itself should have its own real dts ... like we did with rk3288-evb* for example
<mmind00>
rperier: correct, for the dynamic stuff on the pin headers this will be ideal
<karlp>
beagleboard capes need the same sort of thing.
<rperier>
what I just mean, is that's good to share things when it is possible
<karlp>
will be nice when the overlay stuff settles down I'm sure
<karlp>
heard some horror stories of trying to get it to work on BBB at present though :)
<rperier>
karlp: this is exactly what a kernel developer said at the last kernel submit when it talked about devicetree overlays, he talked about BBB as an example
<rperier>
:)
<rperier>
(if I remember correctly)
RayFlower has joined #linux-rockchip
<naobsd>
for now, should I make multiple dts for each variant?
<naobsd>
2 for rayeager (1GB/2GB RAM), 3 for firefly (beta, production 1GB/2GB RAM)
<karlp>
rperier: yeah, BBB is probably the most common place where you'll see modular hardware that isn't usb/pci(e) expansions
<karlp>
naobsd: for the firefly and rayeager, should be able to make .dtsi for the underlying hardware.
<naobsd>
(firefly beta should be very few, it may be omitted)
<naobsd>
ah, I'll make .dtsi for common part
<naobsd>
+2(3) dts
<naobsd>
cnxsoft: thank you for good article :)
<naobsd>
I think that tool will work on Linux on RK
<rperier>
I should receive my firefly soon btw
<naobsd>
by recompiling Tools/*

so I will be able to help (for mainline)

at first, git.linux-rockchip.org is our community mirror, more specifically, it's my mirror
<naobsd>
I never made any hardware product with rk3188/rk3288. if someone says "it must be provided!", my answer is "ask your vendor"
<linuxium>
naobsd: you are recommending PopMetal dev board?
<naobsd>
Radxa and Firefly releases their SDK by some ways. git.linux-rockchip.org is not only single way to get it. and, again, it's my mirror. I never guarantee it' always working.
<naobsd>
if someone says "I can wait maintenance, but it should be finished soon", it must be wrong. anything in linux-rockchip community is done by someone's free time.
<naobsd>
I have to use some money and time to keep that mirrors.
