    Hello,

    I'm using Torpedo wireless SOM. So I make bootable SD card to boot from NAND. In the U-boot, I run script makeyaffsboot, and after that my device will boot from NAND. Basically I need UART serial connection to run this script, so my question is how I can change this script or u-boot to automatically start this script if there is no image in NAND. I don't want to have UART connection at all.  For the first boot of system, I want to place SD card with NAND image, device will recognize that there is no image in nand, run this script, write image to NAND and boot, start the kernel. After that, kernel will be started from NAND every next boot.

    I know that I can ask LogicPD to program NAND for me, but this is better solution when I have small serie.

    Regards

    Please see section 6.3 in the AN542 DM3730 - AM3703 SOM Programming for End-Product Manufacturing application note[1] describing the steps to program your Linux OS from a SD Card automatically.
