can't find firmware file in yocto build folder

rans — Wed, 20 Mar 2024 12:46:36 GMT

Hello,

I hope someone can help with the following.

I've build yocto image for ls1046ardb (I've bitbaked for both main and tiny images)

Yet, I don't find any firmware file (firmware_ls1046ardb_sdboot.img) , and also can't find any kernel file (
( boot_ls1043ardb_lts_6.1.tgz ),

Thanks,

rans

please share with me the steps you are following to try to generate the images, and also please share the log when you do bitbake.
I need to check if something was missing or if there something wrong.

@LFGP

Sure, the steps are as described in Rev. L6.1.36_2.1.0 — 9 November 2023 , chapter 3.7.7 (LS1046ARDB) and chapter 3.5.4 - bitbake commands i.e.

DISTRO=fsl-qoriq-distro MACHINE=ls1046ardb source distro-setup-env
$ bitbake ls-image-main
and

bitbake qoriq-composite-firmware

and then I would like prepare SD as mentioned in step 4

Writing image to SD card:

$ flex-installer -b tmp/deploy/image/<board> bootp_xxx.tgz -r tmp/deploy/image/<board>/ls-image-main-xxx.tar.gz -f tmp/ deploy/image/<board>/firmware_sdboot_secure.img -d /dev/ sdx

But though I have the firmware<> file and rootfs file ls-image-main<>.tar.gz, I still can't find any boot<>_file (not file starts with boot prefix)

Is it some other file maybe ? (see the original post with file list)
Is the tiny build should be used only for minimal boot and for programming other storage device ? If this is the case it means that flash qspi can't be used for booting customized linux, Right ?

Thanks!

@rans

regarding your questions:

Is it some other file maybe ? answ: no, the mentioned are the rights.

Is the tiny build should be used only for minimal boot and for programming other storage device ? answ: Yes, it is intended for that.
If this is the case it means that flash qspi can't be used for booting customized linux, Right ? answ: right.

Please share the output logs in order to analyze them and try to detect some missing, due from my side the images was generated as expected.

Hi @LFGP

After installing the build (as-is from sources) yocto and deploying it in SD card, I insert card, and starts boot, but then in login, I can't pass the login...

I tried login: root, but it then asks for password (?)

ls1046ardb login: root
Password:

I tried to enter in password: just enter/root/... but nothing passes.

see complete boot log from sd

Any idea ?

the user/password is: user/user

I am not sure why it is not written in documentation....

I also suggest to add the command " bitbake generate-boottgz" to table 7 (3.5.4), it may save others who struggled on the same stuff
