I've been trying to reproduce here but not having any luck so far. I'm using the 2.31 Davincii Serial Boot and flashing utilites [1], Mono 2.10 and the parent of commit f1d2b313c9eb6808d30c16a9eb5251240452a56c: '4fff329 nand_boot_fsl_nfc.c: make "nfc" a "static const" pointer' I build u-boot with 'make mrproper; make da850evm_config; make -j9 all'; I create an ais_output.bin with 'mono /media/unixdata/src/OMAP-L138_FlashAndBootUtils_2_31/OMAP-L138/GNU/AISUtils/HexAIS_OMAP-L138.exe' I erase the SPI flash with 'mono /media/unixdata/src/OMAP-L138_FlashAndBootUtils_2_31/OMAP-L138/GNU/sfh_OMAP-L138.exe -erase -p /dev/ttyS0' I write the SPI flash with 'mono /media/unixdata/src/OMAP-L138_FlashAndBootUtils_2_31/OMAP-L138/GNU/sfh_OMAP-L138.exe -flash_noubl ais_output.bin' and the contents of my OMAP-L138.ini are as yours: [General] busWidth=8 BootMode=SPIMASTER crcCheckType=NO_CRC [PLLANDCLOCKCONFIG] PLL0CFG0 = 0x00180001 PLL0CFG1 = 0x00000205 PERIPHCLKCFG = 0x0000000a [EMIF3DDR] PLL1CFG0 = 0x15010001 PLL1CFG1 = 0x00000002 DDRPHYC1R = 0x000000C4 SDCR = 0x0A034622 SDTIMR = 0x184929C8 SDTIMR2 = 0xB80FC700 SDRCR = 0x00000406 CLK2XSRC = 0x00000000 [INPUTFILE] FILENAME=u-boot.bin LOADADDRESS=0xC1080000 ENTRYPOINTADDRESS=0xC1080000 I would like to help you debug the operation of UBL-free boot with relocation -- can you give me more details on your setup to help me reproduce here?
