Yeah, we basically discovered thru, as long as you never update MLO/u-boot. It likes to find MLO within a certain window on the disk itself, almost as if it still in a simple raw mode… FAT is simple enough, that you could read a file like this. the I2C protocol on the BBB and create a simple Beaglebone Black I2C application. BeagleBone Black, am335xevmdefconfig, am335xevmdefconfig. While the bootrom supports FAT, it does seem to be a very basic implementation. This document covers the general use of Linux Core Release of U-Boot on following platforms. Theory: (this also applies to the omap3 beagle, which only supports FAT mode…) Make sure the boot flag is enabled (which your does show…)Ĭopy the MLO file first, then call ‘sync’… Then copy u-boot*.bin over… I have compiled u-boot, booted the board via UART and loaded u-boot via xmodem.

For the sake of learning I want to put u-boot on the flash myself and build linux from scratch. While TI doc’s say FAT32, i disagree, FAT16 was a ton more reliable, so use the “-F 16” option with mkfs.vfat… I got a beaglebone black which comes with u-boot linux preinstalled on the emmc. After doing some reading, it looks as though it. Usually it will find something in the onboard eMMC and boot from there. In default mode (S2 not pressed) it tries to boot from MMC1 (onboard eMMC), MMC0 (microSD), UART0, USB0. What did you use to partition the drive? For, sfdisk was always the most reliable. Im having some trouble understanding the location where U-Boot saves its environment for BeagleBone Black. The BeagleBone Black provides by alternative boot sequences which are selectable by the boot switch (S2). Hi, while looking over your post a few things come to mind…įirst this randomness is exactly the reason we switched to raw mode…Īre you using virtualization (VMware/VirtualBox/etc?) This always seems to get in the way between writing data and the usb media…
