- Subject: [PATCH] ARM: dts: stm32: fix stm32mp157c-odyssey card detect pin
- MIME-Version: 1.0
- Content-Type: text/plain; charset=UTF-8
- Content-Transfer-Encoding: 8bit
- The microSD card detect pin is physically connected to the MPU pin PI3.
- The Device Tree configuration of the card detect pin was wrong—it was
- set to pin PB7 instead. If such configuration was used, the kernel would
- hang on “Waiting for root device” when booting from a microSD card.
