buildroot kernel get stuck using imx_v7_mfg_defconfig

christsang — Mon, 30 Apr 2018 06:35:48 GMT

Hi everyone,

I am using the Buildroot 2018.02 for my development on IMX7Dual Sabre Board. Recently I want to enable mfgtools package to update the FW using the mfgtools.

In mfgtool readme, there are following option which have to be set and so I just follow that.
#################################################################
Make sure to enable the following Buildroot options:

BR2_PACKAGE_FREESCALE_IMX=y
BR2_PACKAGE_IMX_UUC=y
BR2_TARGET_ROOTFS_CPIO=y
BR2_TARGET_ROOTFS_CPIO_GZIP=y
BR2_TARGET_ROOTFS_CPIO_UIMAGE=y

Also modify your kernel configuration to have:

CONFIG_USB_GADGET=y
CONFIG_USB_MASS_STORAGE=y
CONFIG_FSL_UTP=y
CONFIG_MMC_BLOCK_MINORS=16
#################################################################

For the kernel defconfig, I chose imx_v7_mfg_defconfig. And the kernel version is rel_imx_4.9.x_1.0.0_ga.

I can really successfully build the uboot, kernel and rootfs, as well as the sdcard.img. And then I test the sdcard.img using dd command to my board. However the kernel get stuck everytime at similar position and I will show the log later.

Well I also try to use mfgtool to update the same FW. Sending and burning processes uboot, kernel, rootfs, device tree can all pass without any error. After the mfgtool process is done, the kernel still get stuck get that position every time during boot up.

Here is the log and please advice. Thanks all!

Hello,

mfgtool doesn't need any changes to perform the software update, you only need to update the folder with the new image that you are willing to use and use the GUI as usual.

Best Regards,

Diego.

Hi Diego,

The mfgtool is fine. But I have to use the mfg defconfig for the kernel right? Otherwise I cannot use the mfgtool properly.

Hi,

Please follow below steps to update the FW for i.MX7D SABRESD board.

Method - 1 Using dd command

Choose freescale_imx7dsabresd_defconfig for the kernel defconfig.
Build the images using make command.
Flash sdcard.img image file using below command.
- sudo dd if=sdcard.img of=/dev/sdx bs=1M && sync

Method - 2 Using MFGTool

Replace the u-boot, zImage (kernel image) , device tree file (dtb file) and rootfs in MFGTool /Profiles/Linux/OS Firmware/files folder.
Rename the file with respective names used by MFGTool.
Use mfgtool2-yocto-mx-sabresd-sdcard-sd1.vbs script file to flash the images using MFGTool.
Change the following coomand in ucl2.xml file to flash the rootfs as rootfs extension generated by buildroot is .tar while in ucl2.xml it is .tar.bz2.
- <CMD state="Updater" type="push" body="pipe tar -xv -C /mnt/mmcblk%mmc%p2" file="files/rootfs_nogpu.tar" ifdev="MX6UL MX7D MX6ULL">Sending and writting rootfs</CMD>

Hope this will be helpful to you.

Regards,

Shivani.

Hi Shivani Patel,

It works. But I still wonder why I cant use the imx_v7_mfg_defconfig for the kernel build. Anyway thanks a lot for your help.

shivanipatel — Wed, 09 May 2018 13:08:06 GMT

Hi Chris Tsang,

The images built using imx_v7_mfg_defconfig should be kept in MFGTool \Profiles\Linux\OS Firmware\firmware\ folder as these images are the manufacturing tool images and the images built using freescale_imx7dsabresd_defconfig defconfig which internally used imx_v7_defconfig defconfig are default images and they should be placed in MFGTool /Profiles/Linux/OS Firmware/files folder.

Hope this will be useful.

Regards,

Shivani.
