Jetpack5.0.2+jetson xavier NX 烧录系统后不开机

你好,
jetpack5.0.2+jetson xavier NX+ 我们自己的开发的底板(无eeprom),目的是将NX模块作为EP模式,然后只修改ODMDATA的值为:0xB8191000,sudo ./flash jetson-xavier-nx-devkit-emmc mmcblk0p1 后,烧录过程没有异常,提示烧录完毕后,但是设备没有看到NVIDIA的开机桌面,设备重新上电,也是不能进入系统。在不修改ODMATA的值时烧录系统是设备是可以进入到桌面的。

Hi,

Please upgrade to jp5.1.2 first. Too many patches are not there on jp5.0.2.

你好,
已经升级到JP5.1.2,但是刷入EP模式后还是不能开机,开机日志如下:
teraterm.log (46.6 KB)
谢谢!

Hi,

Which PCIe are you trying to enable as EP?

你好,
x4和x1
谢谢

No, I mean the hardware pin…

Also, as the design guide mentioned, only C5 could be EP mode…

你好,
我们把PCIEx4这一组作为EP模式,已经设置为C5:

谢谢!

請你把tegra194-p3668-p3509-overlay.dtbo用dtc tool編回dts檔

然後把裡面的fragment@7的內容

odm-data = “enable-pcie-c5-endpoint\0enable-nvhs-uphy-pcie-c5”;

改成

odm-data = “pcie-c5-endpoint-enable”

整機重燒之後看看能不能開


Please modify the dtbo overlay from the original odmdata value to the following one and do full flash.

非常感谢!可以了
