    hi dave. i came across this because i'm also interested in doing the same. (but fedeora server instead). any luck to get this to work? the asus engineers just came out with kernel 5.10 in Oct 2023.

  3. Posted

    I am referring to https://github.com/TinkerBoard-Linux where the newer kernel 5.10 is found.

    I want to build the uboot.img and trust.img and flash them onto an empty SD card. meaning, there's no partition on it yet.

    How should i do it?

    Note: I am familiar with how to build a kernel. but not sure how to flash it onto empty sd card also.

     

    I found the partition list here http://opensource.rock-chips.com/wiki_Partitions --> should i just sudo dd and write them into the respective locations and thats it?

    Yea I think it'll work. I copied the modules over. Will enable it and try. But I believe it'll work. Thanks!

    Also, can I please trouble you to help upload the kernel resources for 5.10 to git so that I can customize my kernel and the modules?

    seems like might be a driver issue? since lscpi is showing hardware results.

     

    Note: I used debian 11 v3.0.6 --> but I used debootstrap to install a variant of ubuntu instead. which probably didn't install the driver (i think?)

    I reinstalled debian onto the tinkeboard 2s, and added the below to /etc/network/interfaces

    # Add the following (for ethernet):
    auto lo eth0
    allow-hotplug eth0
    iface lo inet loopback
    iface eth0 inet dhcp

     

    However, when I did: 

    ifconfig

    It produced the below result:

    As you can see, wlan / wlp1s0 is not found in there. As such, I am unable to connect via wifi / bluetooth.

     

    Is there a driver / kernel / firmware that I can use to update the drivers so that the wifi and bluetooth modules are detectable?

    I was trying to enable config for bpf in tinker_def_config.

    # Bpf config
    CONFIG_BPF=y
    CONFIG_BPF_SYSCALL=y
    CONFIG_BPF_JIT=y
    CONFIG_NET_CLS_BPF=y
    CONFIG_NET_CLS_ACT=y
    CONFIG_NET_SCH_INGRESS=y
    CONFIG_CRYPTO_SHA1=y

    But came up with these errors:

    Hello, after 2 years of working with tinkerboard 2S, i am still unable to build a custom kernel and make adjustments to my use case.

    Please, could you share detailed documentations / guide on how we can create a custom kernel with uboot , and how we can install it into the tinkerboard?

    i'm a fan of asus product, and i use tinkerboard for IOT work. but there are very very limited resources on how to put our own customization in.

    please help..
