![]() The comments on the QSPI pad assignments erronously swapped the qspi1_d0 and qspi1_d1 functionality and could cause confusion. QSPI1_D[0] is in fact muxed on pad U1 (gpmc_a16), and QSPI1_D[1] - on pad P3 (gpmc_a17). Fixing comments. Signed-off-by: Lubomir Popov <l-popov@ti.com> Reviewed-by: Tom Rini <trini@ti.com> |

Summary ======= This document covers various features of the 'dra7xx_evm' build and some related uses. eMMC boot partition use ======================= It is possible, depending on SYSBOOT configuration to boot from the eMMC boot partitions using (name depending on documentation referenced) Alternative Boot operation mode or Boot Sequence Option 1/2. In this example we load MLO and u-boot.img from the build into DDR and then use 'mmc bootbus' to set the required rate (see TRM) and 'mmc partconfig' to set boot0 as the boot device.
