Subject: [U-Boot] [PATCH v2 12/12] am65x: README: Add eMMC layout and flash instructions
Date: Tue, 4 Jun 2019 17:55:55 -0500 [thread overview]
Message-ID: <20190604225555.12186-13-dannenberg@ti.com> (raw)
In-Reply-To: <20190604225555.12186-1-dannenberg@ti.com>
From: Faiz Abbas <faiz_abbas@ti.com>
Add instructions for flashing boot images to the eMMC with a
layout of the address where each image needs to be flashed.
Also add instructions to flash filesystem partition in user
partition and boot kernel from the rootfs.

+ROM supports booting from eMMC from boot0 partition offset 0x0
+
+Flashing images to eMMC:
+
+The following commands can be used to download tiboot3.bin, tispl.bin,
+u-boot.img, and sysfw.itb from an SD card and write them to the eMMC boot0
+partition at respective addresses.
+
+=> mmc dev 0 1
+=> fatload mmc 1 ${loadaddr} tiboot3.bin
+=> mmc write ${loadaddr} 0x0 0x400
+=> fatload mmc 1 ${loadaddr} tispl.bin
+=> mmc write ${loadaddr} 0x400 0x1000
+=> fatload mmc 1 ${loadaddr} u-boot.img
+=> mmc write ${loadaddr} 0x1400 0x2000
+=> fatload mmc 1 ${loadaddr} sysfw.itb
+=> mmc write ${loadaddr} 0x3600 0x800
+
+To give the ROM access to the boot partition, the following commands must be
+used for the first time:
+=> mmc partconf 0 1 1 1
+=> mmc bootbus 0 1 0 0
+
+To create a software partition for the rootfs, the following command can be
+used:
+=> gpt write mmc 0 ${partitions}
+

+Kernel image and DT are expected to be present in the /boot folder of rootfs.
