| Explore the Kernel make install secret |

I have used Linux for quite some years but SBC is new to me.
I have an Atheros AR9271 network card which is plug-n-play on RPi. On rock64, lsusb recognize it out of the box. Google says I need the following in my kernel to make it works.
Quote:CONFIG_ATH_COMMON=m
CONFIG_ATH9K_HW=m
CONFIG_ATH9K_COMMON=m
CONFIG_ATH9K_HTC=m
I use ayufan's stretch-minimal-rock64-0.5.15-136-arm64.img
I use sdcard (instead of emmc)
I use serial console
To take advantage of the 4G ram, I compile the kernel on board instead of using CC.
A brief summary of steps I take, after apt update upgrade
Quote:$ sudo apt-get install python2.7-minimal
$ sudo ln -s python2.7 python ... at /usr/bin
$ sudo apt-get install libncurses5-dev bc
$ git clone --depth 1 --single-branch -b release-4.4 https://github.com/ayufan-rock64/linux-kernel
$ cd linux-kernel
$ make rockchip_linux_defconfig
$ make menuconfig ... to config ATH9K
$ make -j 5
then ...
I had tried a couple of combinations of
Quote:sudo cp ./arch/arm/boot/*(u)*(z)Image ./arch/arm/boot/dts/*.dtb <boot-partition>
sudo make modules_install
sudo make firmware_install
from https://github.com/umiddelb/armhf/wiki/H...ARM-device (a copy from ODROID Magazine)
No luck. But it took almost 3 hours every time I dd back the pre-make-install image onto my 32G sdcard.
I read
http://opensource.rock-chips.com/images/...170711.pdf
referred by Port Arch Linux to Rock64
https://me.m01.eu/blog/2017/12/rock64-arch-linux/
On which, after kernel compilation, it is rootfs compilation. Not apply on my case, but directs me to think that my problem is very rock64 specific.
I enter the freshly learned u-boot shell, run printenv
I trace bootcmd -> distro_bootcmd -> list of boot_targets (mmc0 mmc1 usb0 pxe dhcp) and some how I noted from somewhere that sdcard is mmc1 -> setenv devnum (what is it relevant to?) 1 -> mmc_boot ... ... where should I refer to in order to understand what they are? Should it be from u-boot or rock64? Must I learn it all in order to do a "make install"?
Luke had responsed to a similar question on https://forum.pine64.org/showthread.php?...9#pid35059
For the IRC Log
I searched "make install" in #Rock64 channel, it appears 10 times only.
The only one that is about kernel installation is in a conversation between ayufan and xalius.
ayufan asked xalius how he install the kernel, xalius answered "copy". Of course, why should they detail the details in their conservation. Good to know "copy" works.
For the link to "all you need to know"
which is in fact https://github.com/ayufan-rock64/linux-build
docker? okay, why not give it a try if it works, I can learn something new too. I set up a Ubuntu 17.10 vm, installed docker-ce and binfmt support, tested work.
the _Next_ step is "make shell". What I get is >> make: *** No rule to make target 'shell'. Stop.
I should expect this because rock64 is for developer. What is broken is my knowledge, not the document.
By the end of the day, I only need to know how to put/link correctly Image, initrd, dtb in rock64 way, am I? Must I get familiar with those developer's stuffs before I can work back those basic/simples?
Rock64 mounts mmcblk1p6 to /boot/efi instead of /boot; with similar set of files named differently at both locations. This is not a secret. But rock64 uses which set to boot; and which is the correct original file to copy?
Any advice on how should I proceed?
Thanks in advance for your help after 10 days of reading in vain.
Hope my experience won't scare away much potential rock64 customers who search and read.

| JTAG on Rock64 |

I see that the rk3328 offers the TCK and TMS pins for JTAG (at the expense of using the SD card). But I don't see any pins for TDI or TDO. On the other hand, the rk3328 development board apparently supports JTAG. Does someone have a schematic for hooking up JTAG to the Rock64?
Thanks,
Tom

Hi,
I have an RK3328 Android TV BOX (Alfawise Z28 Pro) and the Android GUI is limited to 720P.
Does the ROCK64 board run with 1080P resolution for the GUI ?
I think this is because the GPU in the SOC is to weak to drive 1080P.
Thanks
Vasant

I am new to using SOC for development and plan on using RK3399 based android platform for my development. I have few queries as below, it would be really helpful if people on this forum can help with my queries.
a) Does the RockPro64 comes with pre-installed with Android or not? If not what is latest version that is available and supported for this platform? Is the android version pre-rooted?
b) Does this RockPro64 has on board storage available for installing android apps and storing files, if yes then how much?
c) My android app uses native libraries for some performing image processing. Would it help to buy the RockPro64AI instead. If yes, then how much performance gain is expected, when compared to regular RockPro64?
d) Can I use dual camera (5 MP each) on this board? What is the field of view (angle) for the each supported 5MP camera?
e) Can I use the wifi module with this board? Does this wifi module support "Monitor" mode and be used programmatically through Android?
I know it is a lot of queries? But if you can answer even few of them, it would be really helpful.

Its already several days of testing ROCK64 and I'm still getting so much disappointing. I've installed Android 7.1 - could not get neither bluetooth, nor wifi USB dongles working. Installed Linux UBUNTU, managed to get bluetooth and one of the Wifi dongles working, but perfomance of whole system is on level of pentium 1 1980year of manufactury - even can not play youtube video at 1080P smooth.
What is your experience with this SBC? What is the best distributive/OS to run on this board kindly presented through pine installer?
P.S. I bought this board in maximum options (4GB RAM) to build CarPC, however my feelings at the moment - I wasted another 100USD

| Upgrading to pre-release failure |

Hi,
I just upgraded from 0.6.15 to 0.6.22 of xenial minimal install. Now i can't ssh to it. When I edit the sources file and ran a apt-get update and apt-get upgrade it said 2 had been held back, which were the new pre-release sources. So I ran an apt-get install instead which seemed to work, but when i did a restart, i can't access it but can ping the IP. Can anyone give some help...
I also have found it impossible with my near limited linux experience to set a static ip address using standard tips from ubuntu forums. Not sure where i'm going wrong...
EDIT
Sorry, my bad, it had changed IP address on me. Now working fine. Not sure why the sudo apt-get upgrade didn't work though.
