Hi Daniel, What I am assuming from your question is that you want to use the TI SDK u-boot and put it onto a BBB SD card with a debian file system. Note that I haven't tried this exact thing but I hope to give you pointers to get started.
The TI SDK assumes a boot partition where it puts the MLO and u-boot.img files (created as part of the script bin/create-sdcard.sh). The BBB Debian image does not create a partition but writes the MLO and u-boot.img files to known locations at the start of the SD card. So stages would be: In TI SDK: $make u-boot This will create the first and second level u-boot executables: *board-support/u-boot-XXXX-YYYY/MLO* and *board-support/u-boot-XXXX-YYYY/u-boot.img* Information on the BBB Debian image can be found at ( https://www.digikey.com/eewiki/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-SetupmicroSDcard). You should be able to take these two commands to update the u-boot on an existing card with your TI SDK versions. A couple of notes: - See earlier comments in that page for how to set DISK. In my case I set DISK=/dev/sdc as the drive the SD card is mounted to. - I assume here that the mounted SD card already contains a Debian BBB image sudo dd if=./board-support/u-boot-XXXX-YYYY/MLO of=${DISK} count=1 seek=1 bs=128k sudo dd if=./board-support/u-boot-XXXX-YYYY/u-boot.img of=${DISK} count=2 seek=1 bs=384k Iain On Sunday, May 17, 2020 at 7:31:23 AM UTC+1, Daniel Cheng wrote: > > Hi all > > I am newer for BBB. > > I read the document: > > https://www.digikey.com/eewiki/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-Bootloader:U-Boot > But the source code is not from TI SDK. > > I want to build u-boot from TI SDK and flash u-boot into BBB. > > Could anyone help me? > > Thanks > > Daniel > -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
