I built Linux RT for a custom board based upon Beagleboard xM exactly as in Robert C. Nelson's page https://eewiki.net/display/linuxonarm/BeagleBoard.
Here is what I get during boot, tried on a real Beagleboard xM and get the same behavior. The booting stops at a u-boot prompt. U-Boot SPL 2017.03-rc1-dirty (Feb 04 2017 - 12:10:18) Trying to boot from MMC1 SPL: Please implement spl_start_uboot() for your board SPL: Direct Linux boot not active! reading u-boot.img reading u-boot.img U-Boot 2017.03-rc1-dirty (Feb 04 2017 - 12:10:18 -0700) OMAP3630/3730-GP ES1.2, CPU-OPP2, L3-200MHz, Max CPU Clock 1 GHz OMAP3 Beagle board + LPDDR/NAND I2C: ready DRAM: 512 MiB NAND: 0 MiB MMC: OMAP SD/MMC: 0 *** Warning - readenv() failed, using default environment Beagle xM Rev C No EEPROM on expansion board No EEPROM on expansion board OMAP die ID: 101000229ff80000016830c319017022 Net: usb_ether Error: usb_ether address not set.
