Mfgtools download failed for customized i.mx6dl board

[brucesun]

Hi,

We have a customized board based on MX6 Dual Lite SABRE AI CPU Card. When I tried to download image to SD card, Mfgtools reset repeatedly after "no device connected" message. Can anybody help me with this issue? I use Mfgtools-Rel-4.1.0_130816_MX6DL_UPDATER.

Hi Bruce

seems processor failed to enter to Serial Downloader

mode, one can check boot pins, Chapter 8 Avoiding Board Bring-up Problems

IMX6DQ6SDLHDG

or test USB module with i.MX 6Series Platform SDK : Bare-metal SDK

Best regards

igor

Hi Igor,

Thanks for your reply. I can run DDR Stress Tester(v2.00-RC1) so I think serial download mode is OK. But the test failed.

Is this result valid?

The DDR3 device type is MT41K256M16HA-125:E and I use the script MX6DL_ARD_DDR3_register_programming_aid_v0.2 without modification. The DDR density is set to 2G and 4G doesn't work for the tester.

Hi Bruce

had you rebuilt mfg tools firmware as described in attached

document sect.3.9 Building Manufacturing Firmware with

new ddr settings (from ddr tester) in uboot flash_header.S.

Hi Igor,

Our board is based on SABRE AI DulaLite card. For the DDR3 part of the board, we use the same components and keep the schematics and layout. So I just use the images for SABRE-AI DL board. I also tried to boot the board from SD card with images for Sabreauto-SD but no output from console port.

Hi Bruce

even you copied design from SABRE AI DulaLite card, you should

rebuild mfg tools firmware for that speciifc board.

Best regards

Hi Igor,

I tried the usb loader as specified in http://boundarydevices.com/unbricking-nitrogen6x-sabre-lite-i-mx6-board/ to download u-boot image to our board but failed. I tried the u-boot images from android_L5.0.0_1.0.0-ga_images_6qsabreauto, yocto build with bitbake u-boot-imx-mfgtool and bitbake core-image-minial but none of it worked.

I uses the same tool to try on the IMX6QSABREAUTO evaluation board and it worked fine.

Any idea for this board?

Regards

Bruce

Hi Bruce

suggest to run ddr test

https://community.freescale.com/docs/DOC-96412

and rebuild mfg tools firmware or uboot (dcd header with

new ddr settings obtained from ddr test) or whatever else

you are going to run, should be built with new ddr settings

obtained from ddr test for that speciifc board.

Best regards

Hi Igor,

For us the first thing is to run DDR stress test successfully on our board but we failed at this step. We checked the schematics, layout, components but still no progress. I'll open a new topic about DDR test. Thanks.

Regards,

Bruce
