TE0820: UBOOT_MACHINE for Yocto Project

[martin]

Currently I try to set up the TE0820 board with Yocto.
In the first step I used the predefined configurationof the ZCU102 Board (UBOOT_MACHINE = "xilinx_zynqmp_zcu102_revB_defconfig").
But now I want to switch to a own TE0820 configuration.

If I do that the u-boot-xlnx recipe give me weirded errors like "arch/arm/dts/zynqmp-ep108.dtb' failed"

Have you a predefined default configuration?

Thanks,
Martin

The reason for the dtb failed is fixed. It was because the subfolder arch/arm/dts was a file instead of a folder.
The reason for that was the line in the u-boot-xlnx_%.bbappend file

wrong:

Code: [Select]

WORK_SHAREDIR = "${TMPDIR}/work-shared/${MACHINE}/kernel-source/arch/arm64/boot/dts/${MACHINE}"
DTB_SHAREDIR = "${WORK_SHAREDIR}/${DEVICE_TREE}"

do_configure_prepend() {
    ...
    install -Dm 0644 ${DTB_SHAREDIR} ${DTB_BUILDFOLDER}
    ...

correct:

Code: [Select]

WORK_SHAREDIR = "${TMPDIR}/work-shared/${MACHINE}/kernel-source/arch/arm64/boot/dts/${MACHINE}"
DTB_SHAREDIR = "${WORK_SHAREDIR}/${DEVICE_TREE}"

do_configure_prepend() {
    ...
    install -Dm 0644 ${DTB_SHAREDIR} ${DTB_BUILDFOLDER}/${DEVICE_TREE}
    ...

Anyway, it would be nice to get a predefined default configuration as the "xilinx_zynqmp_zcu102_revB_defconfig" for the ZCU102 evaluation board.
