Awesome Work guys, Thanks @hyphop was waiting for this for quite some time now

3

@Spikerguy, maybe your beloved distro can now take also advantage of this uboot !?

4

Only if it can work without the need of cleaning vendor uboot from the emmc.

So will have to try it first.

5

i fear that mainline uboot will not be for you because there will only be one uboot on the emmc : either vendor or mainline

6

this mainline uboot edition have special boot sequence

SPI => USB => SD => NVME => MMC => PXE => DHCP

if u write this u boot to emmc == u can start many OS and distros ( excluded android ) from any external and internal storages by boot sequence prio! without additional manipulation

same u can write this uboot to SD card with your distro
and start system fully from sd (without emmc clean )
by TST mode (tripple press F_KEY) / mask rom mode

  • VIM1 VIM2 Edge - OK
  • this method not work for VIM3 VIM3L (full boot from from sd only if emmc uboot was removed - )

PS: NVME support for mainline uboot not ready for amlogic but for rockhip will be soon (still testing )

7

another feature is easy custom boot logo

uboot LOGO / SPLASH

uboot LOGO, displayed after uboot activate display

LOGO PATHS

+ MMC|SD /splash.bmp                    (1st partition)
+ MMC|SD /usr/share/fenix/logo/logo.bmp (2nd partition)

INFO

file splash.*
splash.bmp       PC bitmap, Windows 3.x format, 32 bit per pixel (bgra - pixel_format)
splash.bmp.gz    gzip compressed data, was "splash.bmp"

raw bmp and gzipped bmp must have same name splash.bmp or logo.bmp
and same .bmp extension (without .gz)

PACK

gzip -9c splash.raw.bmp > splash.bmp

UNPACK

file splash.bmp | grep gzip \
gzip -dc splash.bmp > splash.raw.bmp

CUSTOMIZE

very easy customize boot LOGO, logo-file is simple BMP file (or gzipped BMP)

@hyphop how do I Implement this in my Ubuntu OS build, I did the 3 commands you listed what to do after that ?

9

if it mainline ubuntu builded by fenix (this uboot series already integrated to fenix) its very easy

just create /boot/splash.bmp (1st partition)
or edit /usr/share/fenix/logo/logo.bmp (2nd partition )

10

No no, you got me Wrong i am talking about how to implement mainline uboot in the ubuntu OS what are the steps to implement mainline uboot in my build?

11

all info was provided in 1st topic :wink:

source , binaries, links , docs , manuals …
plz clarify what are u need … ?

12

I am trying to build a Ubuntu bionic server image for my VIM3, please tell me the steps I need to execute to build this OS, I have built a few OSes using fenix before, and i have already done the first three steps you have given,

13

what should be my next step ?
do I run, source env/setenv.sh
and set the same Environment and then run the “make” command ?

14

no need to make some special in fenix (this uboot already integrated)

just download or upgrade your fenix (sync with our repo before use it)

make configuration like this for example

#KHADAS_BOARD=VIM3
#VENDOR=Amlogic
#CHIP=A311D
#LINUX=mainline
#UBOOT=mainline
#DISTRIBUTION=Ubuntu
#DISTRIB_RELEASE=bionic
#DISTRIB_TYPE=server
#DISTRIB_ARCH=arm64
#INSTALL_TYPE=SD-USB

and start make or make uboot

15

Ok @hyphop thanks so much, what do I do to sync the Repo?

16

now to sync fenix pero

cd fenix
git pull
17

Thanks @hyphop will definitely do it and tell you my results :smile:

18

I can give this a try next weekend.
Thanks

I’ve tried to install the VIMx.UBOOT.mainline.emmc.kresq image but it failed according to the screenshot attached. I’ve checked the downloaded image using the Krescue option.
Using VIM3/PRO.
Thanks
Marco
