LS1012ARDB LSDK1903, how to build linux-source

ohara — Wed, 07 Apr 2021 07:59:06 GMT

How to build and install linux-headers and lib-modules on flex-builder?

I tried following procedure and installed imagefiles to SD-card on X86-PC.
On LS1012ARDB, linux boot successfully, however, there are no linux-source
and linux-lib-modules.

I also tried latest LSDK2012, however, it fails on step (2-f).

Sorry, I think this should be posted to "QorIQ" - "Layerscale", not to "iMX"

Use the "flex-builder -i mkbootpartition -a arm32" command instead of the "flex-builder -i mkbootpartition -b sd -a arm32 -m ls1012ardb".

I tried "flex-builder -i mkbootpartition -a arm32", but it fails as follow,

----

Building UEFI ...

I also found there are no headers and lib-modules in ./build/image/rootfs_XXXX.tgz

So I give-up to use LSDK1903, and try latest LSDK2012

I tried these procedure (2-a)~(2-f) on LSDK2012, need to modify as
(2-f) $> flex-builder -i mkbootpartition -a arm32

This result shows successfully building linux header and lib-modules.
However, by not specifying machine type(-m ls1012ardb) on step (2-f),
bootpartition_xxxx.tgz has only ls1021 related files(*dtb and *scr), instead of "ls1012ardb"

Show me the procedure
(a) how to build "fsl_ls1012a-rdb.dtb" and "ls1012ardb_boot.scr"
and
('b) how to merge these files into bootpartition_xxxx.tgz file

Is there problem for using the "flex-builder -i mkbootpartition -a arm32" command?

> Is there problem for using the "flex-builder -i mkbootpartition -a arm32" command?

As desctibed on last Thursday, there are no *ls1012ardb_boot.scr" on /boot directory, so can not boot.

Pavel — Mon, 12 Apr 2021 17:04:53 GMT

Use the following command sequence:

1. flex-builder -c linux -a arm32

2. flex-builder -i mkbootpartition -a arm32

> 2. flex-builder -i mkbootpartition -a arm32

As describe on last Thursday,
this command creates the profiles(*dtb, *.scr) only for "ls1021a(-qds, -twr)".

There is the following information in LSDK2012 User Guide about LSDK 1906:

No formal support of 32-bit kernel space on 64-bit devices

It looks like this information is correct also for LSDK 2012.

On LSDK1903, I can create ls1012_ardb_boot.scr and fsl_ls1012a-rdb.dtb files,
but can not create linux source by "-c linux".
On the other hand, on LSDK2012, I can not create above *.scr and *.dtb files,

but can create linux source by "-c linux".

In Summary,
LSDK

1903 2012
---------------------------------------------------------- + ---- + ----
$> flex-builder -c linux -a arm32 No Yes
$> flex-builder -i mkbootpartition -a arm32 -m ls1012ardb Yes Fail
$> flex-builder -i mkbootpartition -a arm32 No*1 No*1
*1: create only for ls1021

No longer, does flex-builder support "-m XXXX" machine-type option for "-i mkbootpartirion" command?
