From 3e70251d3615c8b76e80cd29afef852b721070e8 Mon Sep 17 00:00:00 2001 From: Sergey Matyukevich Date: Sun, 4 Jul 2021 18:45:14 +0300 Subject: [PATCH] board/stmicroelectronics/common/stm32mp157: fix U-Boot corruption on the first boot The stm32mp157 images successfully boot only once. Subsequent boot attempts fail to reach U-Boot. The root cause turns out to be in U-Boot corruption during the first boot. The stm32mp1 U-Boot stores its environment at the end of GPT partition named 'ssbl' since v2020.10-rc2. However Buildroot genimage template for stm32mp157 boards creates 'ssbl' partition w/o extra space for U-Boot primary and redundant environments. This patch explicitly specifies 'ssbl' partition size that should be enough for both u-boot.stm32 image (~1M) and both environments (16K).
