environnement variable for u-boot android

Hello

I am trying to put Android on my SabreLite board, i am almost done, but there is still a problem.

I made a sd card of android with the document named "Android User's Guide" and now, i want to boot it on my board, but i have a problem:

Wich u-boot should i use? I want to send it to the RAM with imx-usb-loader (https://github.com/boundarydevices/imx_usb_loader) but when i send it, nothing happen on minicom. Can someone tell me which u-boot i should use and the environnement variable, because the variable setting on the document doesn't work.

Regards

Alexandre

Are you using the sabre lite from boundary devices? (quad core)

I haven't personally used the boundary devices board, but you can try with this u-boot: u-boot-6q.bin

Have you tried using MFGTool?, it makes things a lot easier.

Hi Alexandre,

To use our (the Boundary Devices) Android, the SD card creation process uses device/boundary/mksdcard.sh, not the steps described in the Freescale docs.

Also, the U-Boot build is completely independent thing and U-Boot doesn't live on SD card. Instead, it resides in SPI-NOR.

SergioSolis, our boards don't use u-boot-6q.bin. We use main-line U-Boot, so the output of a build is in u-boot.imx.

More details are available in this page:

http://boundarydevices.com/u-boot-on-i-mx6/

The latest U-Boot binaries are in this page (U-Boot 2014.04) and they don't support MFG tool:

The file u-boot.nitrogen6q is the one for use on SABRE Lite (it does auto-detection of SABRE Lite/Nitrogen6x) and you can update it using the "upgradeu" command by extracting the tar-ball in the release page to a single-partition SD card like so:

U-Boot > bootfile=u-boot.nitrogen6q ; run upgradeu
