Tool/software: Linux
I'm able to create a bootable SD card by my own with a custom image and I already flashed this custom image into the Beaglebone Black eMMC. So, when I apply power to the board, it boots just fine from the eMMC.
However, I've been struggling a lot with hardware accelaration and Weston support in this custom image. That's why I decided to take a look at TI SDK 05_02_00_10.
I created an SD card using the create-sd-card.sh script available at the TI SDK. The created SD card has a boot FAT-32 partition (containing MLO and uboot.img) and a rootfs EXT3/EXT4 partition (containing the filesystem). Currently, I don't have a FTDI cable to complete the setup.sh script, which generates an uEnv.txt for the Beaglebone Black or a minicom script for other boards.
Due to the abscence of the uEnv.txt, I'm not able to boot from the SD card (I'm pressing the S2 button when applying power, I have booted from SD cards before). If I don't press the S2 button when applying power, the boards keeps booting from the working custom image placed at the eMMC.
I'm really stuck right now and would appreciate it very much if someone could point me in the direction of building a working uEnv.txt. From what I understood, I need to place this file into the boot partition. I intend to boot from the SD card alone (no fancy TFTP or NFS stuff).
Thanks.
