Hi,Any and all help is appreciated. Thanks in advance.Question 1 I tried using the sdk to build icestorm (a makefile project).  The sysroot for rpi3 sdk & rpi4 sdk are missing a ftdi.h header.  The target rpi4 builds icestorm okay.  see steps below.
Question 2 What is the procedure to update the meta-raspberrypi repo? An issue with core-image-sato for rpi3 required adding vidal@ws009:~/wkg/yocto-zeus-3.0/raspberrypi4/poky/meta-raspberrypi$ git diff diff --git a/conf/machine/raspberrypi3.conf b/conf/machine/raspberrypi3.conf index 581e47c..43a0a25 100644 --- a/conf/machine/raspberrypi3.conf +++ b/conf/machine/raspberrypi3.conf @@ -18,3 +18,4 @@ UBOOT_MACHINE = "rpi_3_32b_config" SERIAL_CONSOLES ?= "115200;ttyS0"  ARMSTUB ?= "armstub7.bin" +ENABLE_UART = "1"  For rpi4 build I made the same in raspberrypi4.conf  diff --git a/conf/machine/raspberrypi4.conf b/conf/machine/raspberrypi4.conf index 1bcf931..0b91515 100644 --- a/conf/machine/raspberrypi4.conf +++ b/conf/machine/raspberrypi4.conf @@ -18,3 +18,4 @@ SERIAL_CONSOLES ?= "115200;ttyS0"  VC4DTBO ?= "vc4-fkms-v3d" ARMSTUB ?= "armstub7.bin" +ENABLE_UART = "1"Question 3 Why is the header file ftdi.h missing in rpi4 sdk and not used in rpi3 sdk?
