STM32H745i-disco uboot support or device tree

Hi,

I'm curently working on a STM32H745i-disco and need to implement a uboot on it. It doesn't seem to be natively supported. I would like to know if there is a port on going or at least if you have somewhere the linux/uboot device tree for this board. Found it for Zephyr but not Linux / uboot.

Thanks in advance.

After further investigation. Nothing has been done for this board.
It is nonetheless similar to the stm32h743 I'll give a try to port it, an see what's happening.

Probably not, this isn't really a suitable Linux target, perhaps look at what ucLinux is doing, or pick a board from the MPU series, ie STM32MP

    Hi thanks for the fast reply.
    I said Linux because the format of the device tree is the same than u-boot. But I mostly focus on u-boot.

    And I supposed that maybe ST would have a stm32h745.dtsi , a stm32h745i-disco.dts and in my biggest dreams a stm32h745i-disco-u-boot.dtsi maybe available somewhere. It has been done for the stm32h743i-disco yet.

    Thanks
