     I have a problem about mfgtool,our evn is :

     linux 3.10.53 ,imx6q sabresd mfgtool is imx-3.10.53_1.1.0_ga-mfg-tools

(1)  we use 2GB DDR (64bit) for our system,and mfgtool can success to run.

(2)  we take down 2 DDR chip (for 32 bit 1GB DDR),and we change the DDR parameter,and ddr stress test is OK,but we fail to run mfgtool,the mfgtool stop run after starting UTP,the log is as follow:


wm8962-supply: disabling

regulator-dummy: disabling

imx mcc test is registered.

Freeing unused kernel memory: 324K (80bf6000 - 80c47000)

Starting UTP

uuc 0.5 [built Jan  5 2015 14:47:13]

UTP: Waiting for device to appear

UTP: file/device node /dev/utp already exists

cpu_id is 0

(stop here)



(3)  we use the same uboot,kernel,dtb,fs (for mfgtool) in 2GB DDR,and the mfgtool is OK,so I think the filesystem for mfgtool (fsl-image-mfgtool-initramfs-imx6qdlsolo.cpio.gz.u-boot) must match 2GB DDR.


how can I use the mfgtool in 32bit 1GB DDR (in imx6q sabresd)?

or how can I compile the yocto for 32bit 1GB ddr for mfgtool?

can you give me a filesystem for mfgtool in 32 bit DDR (in imx6q sabresd)?


Is everyone can help me?

Best wishes!
