how to build fmc tool for arm64

[__OTL__]

Hi

I want to use fmc on my ls1046a board which running a tiny yocto on it.

I tried to build fmc with this:

flex-builder -c fmc -a arm64 -r yocto:tiny

the log is like 

flex-builder -c fmc -a arm64 -r yocto:tiny
COMPONENT: fmc
DISTRO TYPE: yocto
DISTRO SCALE: tiny
make: Entering directory '/home/LSDK'
make[1]: Entering directory '/home/LSDK/packages/apps'
make[1]: Leaving directory '/home/LSDK/packages/apps'
make: Leaving directory '/home/LSDK'

and I found nothing got built.

Am I doing right?

I am using LSDK21.048

Hi Team

Could you please check this?

Thanks!

Please add "fmc" in IMAGE_INSTALL_append in configs/yocto/local_arm64_tiny.conf

$ flex-builder  -i clean-rfs -r yocto:tiny 

$ flex-builder  -i mkrfs -r yocto:tiny

Thanks, but I have tried this.

It seems there is not dependency for fmc yocto build. Could you try this in your environment ? I'm using LSDK21.04

fmc tool has already been included in yocto:tiny filesystem, please refer to the following.

root@TinyLinux:~# fmc
ERR : PCD file is required

In my case if I add fmc to local_arm64_tiny.conf, I can not build rfs.

Can you build with that?

I used command you wrote above and here is my log.

[yipingwang]

fmc is in yocto:tiny, you can use it directly.

Here's what I got on my yocto:tiny

root@TinyLinux:~# fmc
-sh: fmc: command not found

Please try the pre-built image

$ wget https://www.nxp.com/lgfiles/sdk/lsdk2108/lsdk2108_yocto_tiny_LS_arm64.itb

Yes The prebuild image works well.
But I need to build image for my own board.

I confirmed again fmc won't be built in the yocot:tiny. 
Here's what I have done:

1. clone flexbuild_lsdk2108 repo
2. build one time to fetch the resource

   flex-builder -m ls1046ardb -b sd

3. clean the rfs and rebuild the rfs and itb
   

   flex-builder -i clean-rfs -r yocto:tiny 
   flex-builder -i mkrfs -r yocto:tiny
   flex-builder -i mkitb -r yocto:tiny
   

4. load the image and boot as ls1046ardb
   

   tftp $load_addr lsdk2108_yocto_tiny_LS_arm64_240412.itb
   bootm $load_addr#ls1046ardb

5. there is no fmc tool

   NXP LSDK tiny 2108 (based on Yocto) 
   TinyLinux login: root
   root@TinyLinux:~# fmc 
   -sh: fmc: command not found 

If I add fmc to IMAGE_INSTALL_append of local_arm64_tiny.conf

build rfs will get an error :

Could you try to build it once?

[yipingwang · Accepted solution]

bld -i clean-rfs -r yocto:tiny
bld -i mkrfs -r yocto:devel (FMC, restool are compiled in this step)
bld -i mkrfs -r yocto:tiny  (FMC, restool are copied to tiny rootfs in this step)

I tried your commands, but it failed the same as before.

If I add fmc to IMAGE_INSTALL_append of local_arm64_tiny.conf

it failed with : 

ERROR: Nothing RPROVIDES 'fmc' (but /home/yu/flexbuild_lsdk2108_github/components/rfs/yocto-poky/meta/recipes-core/images/core-image-minimal.bb RDEPENDS on or otherwise requires it)

even after yocto:devel rfs built up.

Do I need some change in the yocto:devel config? 

[yipingwang]

Please don't add fmc in local_arm64_tiny.conf, just use the default local_arm64_tiny.conf provided in LSDK 21.08.

Thanks, it works.
