I've upgraded from 5.10 to 5.15 and can't make GPIO work anymoreI've tried thisgpio_keys {
compatible = "gpio-keys";
input-name = "gpio-keys";
status = "okay";
halt {
label = "Halt";
linux,code = <KEY_POWER>; // Key event to match wit...
I've just made the switch for V4.0.0 (A-TF 2.6, Linux 5.15 but with Barebox instead of U-Boot) using Buildroot as before.I had trouble to bring the system up because of what has been changed in regard to SCMI.The DT node's compatible name was changed...
I'm having trouble resetting the board from linux.Not using a PMIC but discrete power supplies.I followed the app notes and errata, connecting the NRST and CORE_NRST pins with a cap then later a 0R resistor.I'm using a single 100nF cap on NRST.I can ...
EDIT: Found the solution, read for implementationI'm trying to get the MPU to exit from standby. PWR_ON goes to 0 as expected on shutdown, so far so good.I'm using PA2 (WKUP2) but it's not working at all...Is there anything special to setup in the de...
Hi,I'm trying to make a custom board boot, using buildroot with all the official ST releases (tf-a, u-boot, kernel) but it's getting blocked at some point.[ 0.911310] stm32mp1_rcc 50000000.rcc: deferred probe timeout, ignoring dependency

Hi,For the upgrade since I use buildroot I just backported all my changes to the latest ST releases. (TF-A, Kernel)CubeMX 6.6.1 (or any version) doesn't export anything in the DTS for wake-up or even gpio pins.Everything works fine with a 5.10 kernel...
I found the issue, it's caused by a circuit on my board: I use VBUS to control a transistor that pulls down some boot pins in order to upload firmware when plugged as a usb device.There is a capacitor on VBUS that prevents this transistor to turn off...
