If it fails, it falls back to booting u-boot.img. MLO falls back to checking if the uImage exists in a FAT There is a valid uImage present at a defined offset. When falcon mode isĮnabled in U-Boot build (usually enabled by default), MLO checks if Keeping ‘c’ key on the serial terminal pressed. Optionally, in order to enter into U-Boot, reset the board while In this boot mode SPL (first stage bootloader) directly boots the Linux Note:: must be at least the hex size of the file size.īooting from SD/eMMC from SPL (Single stage or Falcon mode) Setenv init_usb 'usb start run args_all args_usb' U-Boot # mmc write $ setenv filesize run set_rd_spec' If using ISC dhcpd an example host entry would look like this: BoardĭM814x ROM (PG1.0) or AM335x ROM (PG2.0 and later) Spl/u-boot-spl.bin and u-boot.img files to boot.
