yes it is. Can you try building for MACHINE = "raspberrypi0-2w-64" and see if it works ? if it does, then perhaps we need to add RPI_KERNEL_DEVICETREE = "broadcom/bcm2710-rpi-zero-2.dtb" in raspberrypi0-2w.conf and see if that helps with 32bit mode. > > Can anyone claim that they have a working Yocto image from the more recent > repos booting on a Raspberry Pi Zero W 2 board? > > Cheers!! > > >
