i.Mx6ULL MFG tool flashing failed

[Geetharajammal]

Hi,

Currently we are trying to flash our new customized i.Mx6ULL board, we are facing the issue in MFG Tool flashing, flashing is hanged during "Jump to OS Image"

and if we check in MFG Tool log we found below errors "Error writing to device 0x79", "Failed to initialize the Memory".

We checked in some community and found that this error can be due to DDR error.

So we tried DDR Stress test and found Stress test is passing, and performed DDR calibration and tried flashing the u-boot.imx with DCD calibrated value, still the above errors are occuring.

Please help us to resolve this issue at highest priority.

Regards,

Geetha

Hi Geetha

except running ddr tool, new calibration coefficients should be put

in uboot/../mx6ullevk/imximage.cfg and mfg tools firmware should be rebuilt

using sect.6.2 Manufacturing Tool, MFGTool attached Yocto Guide.
