I'm trying to boot from SD-card and u-boot doesn't seem to find device tree. I have built my system with buildroot (bootlin st/2023.02.2) overriding the sources for tf-a, u-boot, op-tee and kernel, to be able to boot at least to u-boot (I did write a...

As the title says, when I add the (with or without "regulator-always-on") vdd: vdd { compatible = "regulator-fixed"; regulator-name = "vdd"; regulator-min-microvolt = <3300000>; regulator-max-microvolt = <3300000>; }; or vdd_ddr: vdd_ddr { ...

I'm using minimal device tree files to get a custom (MYIR MYC-YF135) board to boot. At the moment I'm stuck when OP-TEE should give the control to u-boot. The boot stops on error message: No serial driver found .... F/TC:0 0 _regulator_enable:150 v...

I went down the rabbit hole and managed to find, that the problem is clock, but I still don't know what is wrong:uclass_find_device_by_ofnode (uclass.c) tries to find device node for rcc@50000000. uclass_get will find it with the key 29 Driver ...

I have forgotten to write, that I'm using the bootlin buildroot release st/2023.02.10

I have tried to debug this by adding print statements to serial-uclass.c.In a function serial_check_stdout the chosen console is found serial0:115200n8, node 7780. Later the device uclass ID is UCLASS_SERIAL, but then the device_probe returns -ENODEV...
