flashing the yocto images

[devilavanyaanda]

Yocto images are flashing in imx6slevk but not on custom board designed based on imx6slevk using mfgtool. In custom board, it is stopping at "Jumping to OS image". We are using sdcard to flash the images.

Error shown in mfgtool.log file:

ModuleID[2] LevelID[10]: ExecuteCommand--Boot[WndIndex:0], File is D:\yocto\linux\Mfg_Tools\yacto_tools-FSL\imx-3.10.17-1.0.2-mfg-tools\mfgtools\Profiles\Linux\OS Firmware\firmware\u-boot-imx6slevk_sd.imx

ModuleID[2] LevelID[1]: MxHidDevice::Write() Error writing to device 0x79.

ModuleID[2] LevelID[1]: Failed to initialize memory!

Is there any solution?

Thank you

Hi Devi

stopping at "Jumping to OS image" may indicate board ddr errors,

so recommended to run ddr test

i.MX6/7 DDR Stress Test Tool V2.52

add new ddr calibration settings to uboot/../*.cfg file and rebuild image.

Also mfg tools firmware should be rebuilt, the recipes used to build a

manufacturing tool image are linux-imx-mfgtool and u-boot-mfgtool.

To build a manufacturing image do the following -

$ bitbake fsl-image-mfgtool-initramfs

Hi igor

Thanks for the reply. In our custom board, android KK images are flashing without any errors but yocto images are not flashing. Still should i consider it is an board ddr issue?

Thank you
