imx_builder is a set of Makefile for build u-boot, Linux kernel, atf, scfw, imx-mkimage.  You can call it standalone build.

here is the step to try it. 

You can use  -n for make to get the detail build steps.

ex:  make atf -n 

       make linux.Image -n

L4.14.78_ga as example:

1. Untar  imx_builder_02282019.tgz

2. Read the  Standalone_Build_Preparation.pdf inside to prepare the bsp.

3. Prepare the toolchains(populate_sdk from yocto, get from linaro, get from buildroot, etc.)

4. Prepare scfw toolchains following the SCFW Porting Kit. 

5. Follow the Standalone_Build_Preparation.pdf to check if the Build Structure is correct.

8. Build Structure

L4.14.78_1.0.0_ga as example.

Prepare rel_imx_4.14.78_1.0.0_ga in REL

Make symbol link to REL/rel_imx_4.14.78_1.0.0_ga

Make symbol link to build_i.MX8X

Hi,

Is there any modification need to be done to enable secure boot of imx8qxp?

[CurtisWald]

imx_builder_03122020.tgz, and building the i.MX 8MM, the Makefile has target defined for rootfs.tar, however missing ${FS_TAR_SCRIPT} defined in SETTINGS.MK:

FS_DIR=${PWD}/fs
FS_TAR_DIR=${FS_DIR}/tar
FS_TAR_SCRIPT=${FS_TAR_DIR}/rootfs.tar.gz.sh

Can the full FS_DIR and scripts for all sub directories be provided in imx_builder?

Missing:

fs/tar

fs/ubi

fs/cpio

[BiyongSUN]

At the very initial version of imx_builder, I just add a very small rootfs for test purpose. 

And I decide not to support rootfs any more. But I didn't remove the rules.

Acuatully, I made the small test rootfs by buildroot.

rootfs:rootfs.tar
#       $(RM)  $(ROOTFS_DIR)/dev/null $(OUT_ROOTFS)
#       fakeroot -- sh -c 'mknod -m a=rw $$0/dev/null c 1 3 && cd $$0 && tar jfvc $$1 *' ${ROOTFS_DIR} ${OUT_ROOTFS}
#       $(RM)  $(OUT_ROOTFS_TAR) $(OUT_ROOTFS_UBI)
#       fakeroot -- ${FS_TAR_SCRIPT}  ${ROOTFS_DIR} ${OUT_ROOTFS_TAR}
#       fakeroot -- ${FS_UBI_SCRIPT}  ${ROOTFS_DIR} ${OUT_ROOTFS_UBIFS} ${OUT_ROOTFS_UBI} ${FS_UBI_DIR}

rootfs.tar:
        $(RM)  $(OUT_ROOTFS_TAR)
        fakeroot -- ${FS_TAR_SCRIPT}  ${ROOTFS_DIR} ${OUT_ROOTFS_TAR}

rootfs.cpio:
        $(RM)  $(OUT_ROOTFS_CPIO)
        fakeroot -- ${FS_CPIO_SCRIPT}  ${ROOTFS_DIR} ${OUT_ROOTFS_CPIO}

Hi BiyongSUN‌, thanks for the update.  

Here is script (getSw.sh) to populate the bsp directory.  Using release rel_imx_5.4.24_2.1.0, for firmware-imx, the i.MX_Linux_Release_Notes.pdf had the version (8.8) for this release.  To use other Linux releases, update the TAG and FWR variable for the versions needed.

#!/bin/bash

TAG="rel_imx_5.4.24_2.1.0"
FWR="8.8"

CAF="https://source.codeaurora.org/external/imx"
MAD="wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO"

wget ${MAD}/firmware-imx-${FWR}.bin

for repo in linux-imx uboot-imx imx-atf imx-mkimage; do
    git clone ${CAF}/${repo} -b ${TAG};
done
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Thanks a lot for your script. 

I have a similar one, which remove the .git in linunx-imx, uboot-imx to make the bsp small. 

I think it not part of the imx_builder so far. 

And my initial thought is for customers to understand the standalone build. and easy to see the single steps, which is a little bit hard to read in Yocto.

The imx_builder is for a professional user like you. You can add any new feature like preparing bsp.  

Thanks a lot for your interesting in my imx_builder.
