[Hardware] TX2 reset and discharge, power up/down

Hi all,

we are developing a TX2 carrier board and facing an issue with the reset/reboot:

Often, after a reset (via reset button) or power down (long press on power button) the module needs around two minutes before it can boot/start again.
The discharge circuit works and is implemented similarly to the eval board.

Any ideas?

Thanks in advance,
Bernhard

Hi, did you measure the power on/down sequence as that in OEM DG? This seems like some signal/voltage is held and discharge slowly.

Hi,

discharging of all voltages, except the TX2 supply (12V in our case), that are connected to the module works as expected.

Also, this error occurs somehow randomly and not with every reset or power off/on. Can this be software dependent?

best,
Bernhard
