mx6q quard preassembled uboot flashing

LLlypukag3e2010 — Wed, 09 Sep 2020 07:14:28 GMT

Hi everyone!

Can smb help?

i have a braded unit with ubuntu 13.04 onboard and EOL support from manufacter.

BoardID: MX6Q/SDL-SabreSD. 2GB Ram onboard,

inside is old 2013 uboot without "stop load" function. it flashed to spi separately. partition with uboot mount in system with rw support.

I'm going to flash it by this manual https://boundarydevices.com/programming-emmc-on-i-mx-platforms/ and try pre-compilied ubuntu 18.04

I found uart and connected to console

so here is question:

Is it possible to use pre-assembled uboot for this platform https://boundarydevices.com/wiki/bd-sl-imx6/ (from wiki boundarydevices) instead of original? i think there are ohther boardid but hardware is identic

Hi LLlypukag3e2010

one can try, however this manual is for https://boundarydevices.com/wiki/bd-sl-imx6/

board, not NXP "SabreSD", so in general there is chance that it will not work.

Best regards

Hello, Igor. can you try to explain differences between that platforms?

as i see from description - they are almost similiar. main diference -2gb ram in my "SABRESD" instead 1gb in "boundarydevice". oh, one more thing - it's call "SABRE Lite" formerly.

https://boundarydevices.com/sabre-lite-name-change-bd-sl-i-mx6-built-to-freescale-sabre-lite-design/

main reason of question - i couldn't found jtag pins on my board, so in case wrong u-boot device just will be brick. and recover will be possible only with tl866...(

anyway, i'll share result of my experiment.

one can look at NXP i.MX6Q Sabre SD documentation

provided links were given to make decision: what actual board in hands - Sabre SD or Sabre Lite

(as uboot logs may be misleading). Based on that you can proceed with flashing proper image.
