However, avoiding the eMMC and using the uSD card is safer when +working with U-Boot. + +If you choose to hand format your own bootable uSD card, be +aware that it can be difficult. The following information +may be helpful, but remember that it is only sometimes +reliable, and partition options can cause issues. These +can potentially help: + +* https://git.ti.com/cgit/arago-project/tisdk-setup-scripts/tree/create-sdcard.sh +* https://elinux.org/Beagleboard:Expanding_File_System_Partition_On_A_microSD + +The simplest option is to start with a standard distribution +image like those in `BeagleBoard.org Distros Page +`_ and download a disk image for +BeaglePlay.

Remember to sync +and unmount (or Eject - depending on the Operating System) the uSD +card prior to physically removing from SD card reader. + +Also see following section on switch setting used for booting using +uSD card. + +.. note:: + Great news! If the board has not been damaged physically, there's no + need to worry about it being "bricked" on this platform. You only have + to flash an uSD card, plug it in, and reinstall the image on eMMC. This + means that even if you make a mistake, you can quickly fix it and rest + easy. + + If you are frequently working with uSD cards, you might find the + following useful: + + * `USB-SD-Mux `_ + * `SD-Wire `_ + +Flash to eMMC +------------- + +The eMMC layout selected is user-friendly for developers. The +boot hardware partition of the eMMC only contains the fixed-size +tiboot3.bin image. This is because the contents of the boot partitions +need to run from the SoC's internal SRAM, which remains a fixed size +constant. The other components of the boot sequence, such as tispl.bin +and u-boot.img, are located in the /BOOT partition in the User Defined +Area (UDA) hardware partition of the eMMC.
