Dear everybody,

I'm trying to use fsl-image-mfgtool-initramfs to run small application on RAM by MFGTool but I don't know how to press Ctrl-C and login to linux initramfs to run my application manually.

In the attachment file is script for mfgtool to flash linux-mfgtool-initramfs to my imx6dl-sabresd board.

Could you please give me a suggestion for this problerm? thanks !

Hi linh dong,

I think you may need to flash rootfs to login to the linux.

All the best

Hi Kane Jiang,

Thanks for your reply. As your suggestion, we can flash rootfs.tar.bz into ramfs and run it directly, right?

I just want to test on ram without flash to eMMC. I have edited and changed to flash rootfs but it can't boot.

old : <CMD state="BootStrap" type="load" file="fsl-image-mfgtool-initramfs-imx6dl.cpio.gz.u-boot" address="0x12C00000"
loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" >Loading Initramfs.</CMD>

new:

<CMD state="BootStrap" type="load" file="rootfs.tar.bz2" address="0x12C00000"
loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" >Loading Initramfs.</CMD>

I don't know how to build rootfs.cpio.gz.u-boot.

Hi linh dong,

I am sorry for misunderstanding your question, it may be correct for file="fsl-image-mfgtool-initramfs-imx6dl.cpio.gz.u-boot".

The following link has some useful information , but I understand that you may still having problems.

IMX6 - booting to a roofts on ramdisk (Boundary Sabre-lite)?
