Hi DaneLLL,
I am using TX2 with custom carry board.
I try to use ODMDATA = 0x07090000; ,for my custom carry board has three USB3 and no PCIe.
But it seem the ODMDATA dont modify anything.
After i modify ODMDATA = 0x07090000; and the readout lane0…4 belong to as follow:
nvidia@tegra-ubuntu:~$ sudo devmem2 0x02520284 b

I change ODMDATA to 0x06090000 or 0x07090000 in p2771-0000.conf.common file
process_board_version()
{
local board_id="${1}";
local board_version="${2}";
local bdv=${board_version^^};
local bid=${board_id^^};
local uboot_build=500;
local fromfab="-a00";
local tofab="-c03"; # default = C03
local pmicfab="-c00"; # default = C00
local bpfdtbfab="-c00"; # default = C00
local tbcdtbfab="-c03"; # default = C03
local kerndtbfab="-c03"; # default = C03
ODMDATA=0x6090000; # default = C0X
#
# Board version is Alpah-Numeric value.
#
then flash kernel as
sudo ./flash.sh -r -k kernel jetson-tx2 mmcblk0p1
i have modify a00-base.dtsi as
