From 76594fb45d0de47ba1ea004d2eb1963f799e36c4 Mon Sep 17 00:00:00 2001 From: Otavio Salvador Date: Fri, 22 Mar 2019 09:25:35 -0300 Subject: [PATCH] pico-imx6ul, pico-imx7d: Explain how to use eMMC user partition The default U-Boot environment expects the use of eMMC user partition. To ensure we are using the proper eMMC partition for boot we need to run the `mmc partconf` command. This patch updates the README instructions to avoid users to follow misleading instructions.
