Hi! I'm working with a STM32MP157c-eval board. I found out that in the Starter Package image the etnaviv module is blacklisted. Isn't it the GPU driver? Why is the galcore module loaded as out-of-tree module instead?
Moreover, when I play the demo video, core usage reaches up to 70%, so is the GPU really working? The blacklist file:root@stm32mp1:~# cat /etc/modprobe.d/blacklist.conf blacklist etnavivDmesg:root@stm32mp1:~# dmesg | grep galcore [ 19.326759] galc...
Resolved! Where should I write pinctrl bindings in device tree for STM32mp1 board with RGB interface : in panel node or in ltdc node ?
CubeMX generates pinctrl bindings inside ltdc node, while here : https://wiki.st.com/stm32mpu/wiki/LTDC_device_tree_configuration pinctrl bindings reside inside panel node
Resolved! What is the Ethernet topology among the Cortex-M and Cortex-A on the STM32MP1
I'm shopping for MCU / MPU hybrid processors like the STM32MP1, targeting applications that need Ethernet connectivity to both the MCU and the MPU. Simultaneous connectivity would be easiest to plan for, but selectable connectivity might also work.I ...

Why some GPIOs are enabled (with status "okay") in stm32mp15xxac-pinctrl.dtsi ? Are they obligatory for proper functioning of SoC STM32MP1 ?
1) Where can I get information on these GPIOs ?2) Can I safely reassign, say GPIOz ?https://github.com/MYiR-Dev/myir-st-linux/blob/develop/arch/arm/boot/dts/stm32mp15xxac-pinctrl.dtsi
