    we thought about this together with our Yocto team. the preffered way (as we already doing with SOF is to have a separate branch)
    but having a tag i think can work for a while.
    do we plan to do this for each SOF release, right?
    zephyr development model looked a little bit different than SOF (I think they have some sort of LTS release every year and keep that for customers)

    I think we'll do this for a while now. one recommendation from Zephyr folks for us to branch a stable release and cherry-pick patches SOF needs. we could host this in SOF github project (we already have a copy of zephyr there)
    probably for all platforms, we'll need a pretty bleeding edge Zephyr in practise, so we'll probably need a few iterations before we can move to use a Zephyr LTS for SOF

    I think that would be a good choice. Initially, I suggested to fork zephyr internally. but i think doing that on SOF github is better.

    @kv2019i can you point me to the script you use the zephyr tagged version? I'm trying to integrate this internally now

    @kv2019i
    hey @dbaluta , sorry, late reply. the script is this one https://github.com/thesofproject/sof/blob/stable-v2.0/scripts/xtensa-build-zephyr.sh
    the 2.0 branch has this bit "# SOF2.0 release uses this commit, verified in 2021-12-03 daily test
    zephyr_fetch_and_switch origin fd089b361d8aebbcb49cca989444aaeb0b6fbb4d"

    Hello @dbaluta , the issue with https://github.com/thesofproject/sof/issues/5077#issuecomment-995533938。 boot with imx8mp-mek-sof-wm9860.dtb, and the kernel is hang on

    @dbaluta
    @lenghonglin yes. this is a known issue. because rootfs is not yet available.
    you have two options
    (1) compile firmware inside linux kernel
    (2) complile SOF as modules <M> and insmod them after kernel boots
    we use (2)

    Daniel Baluta
    @dbaluta
    @lenghonglin yes, that's OK! No you need to install the modules inside your rootfs.
    and then after bootings insmod them.
    I think you can find ho wto do this on google. otherwise, i can help you on Monday.

    @dbaluta Hello

    this is sof firmware in rootfs, but i wanna to build sof which add some logs. <br> i check out sof to cc5ba3393 and build imx8m.
    i replace new sof firmware which i built to /lib/firmware/imx/sof/, but hang on

    lenghonglin
    @lenghonglin
    this is default sof firmware info :
    Firmware info: version 1:5:0-cc5ba
    Firmware: ABI 3:16:0 Kernel ABI 3:11:0
    Linux OK8MP 5.4.70-2.3.0
    i only replace sof-imx8m.ri
    Daniel Baluta
    @dbaluta
    @lenghonglin you are still using linux kernel 5.4
    at least use linux kenrel 5.10
    if you want we can schedule a meeting for tommorrow
    I am on EEST time zone
    lenghonglin
    @lenghonglin
    update kernel 5.10 is a little difficult. The supplier made too many changes on the development board, I don't know which ones he changed exactly.
    i just want to build the same version which add some logs. the default sof firmware version is working fine, and i think check out the right commit(maybe).
    lenghonglin
    @lenghonglin
    I want to find the source code corresponding to the default sof firmware....

    @dbaluta
    @lenghonglin hi
    lenghonglin
    @lenghonglin
    hello~
    Daniel Baluta
    @dbaluta
    clone sof repo
    and to git reset --hard cc5ba33939e
    in this way you should have the same sof version as the one in the release
    Daniel Baluta
    @dbaluta
    hello everyone, we now have our channel #sof under Zephyr discord server
    i think we should stick to discord server when we fully switch to zephyr
