  1. Try to use dtc to un-compile Linux_for_Tegra_tx2/bootloader/t186ref/tegra186-a02-bpmp-quill-p3310-1000-c01-00-te770d-ucm2.dtb by below command.

“dtc -I dtb -O dts -o tx2-bpmp.dtsi tegra186-a02-bpmp-quill-p3310-1000-c01-00-te770d-ucm2.dtb”

  1. add below to the tx2-bpmp.dtsi in the clocks scope

“dtc -I dts -O dtb -o tegra186-a02-bpmp-quill-p3310-1000-c01-00-te770d-ucm2.dtb tx2-bpmp.dtsi”

  1. replace the original tegra186-a02-bpmp-quill-p3310-1000-c01-00-te770d-ucm2.dtb tx2-bpmp.dtsi at …/Linux_for_Tegra_tx2/bootloader/t186ref

  2. sudo ./flash -r -k bpmp-fw-dtb jetson-tx2 mmcblk0p1

clock@plle {
                        clk-id = <0x200>;
                        pll_freq_table = <0x249f000 0x5f5e100 0x2 0x7d 0x18 0xffffffff 0xffffffff 0xffffffff 0xffffffff>;
                };
