We have used NVIDIA Jetson Orin Nx module for our ongoing project, we need to use Sys_reset signal of Orin Nx along with other SOM module reset, But Sys_reset of Orin Nx is 1.8V signalling nature but other SOM works in 3.3V signalling environment. For this we have used a voltage level translator at Sys_reset for converting 1.8V to 3.3V. But this is causing orin NX sys_reset go low which in turn avoiding the Orin to boot up.
So, how to use Sys_reset within a system, are there any recommendations or reference. Please revert ASAP.
We are testing on custom board where we have used a voltage level translator for level shifting Sys_reset from 1.8V to 3.3V. But, the issue is when the sys_rest is connected to the level translator, the Sys_reset is going low and GPU module is not powering ON. when i non mounted the voltage translator IC, The GPU module sys_reset is going high and booting up successfully.
The implementation block diagram of sys_reset is attached for your reference
SYS_RST should not be pulled low by carrier board during boot. It is your level shift issue. You may need to use another one which won’t pull SYS_RST low.
