Hi, I’m using devkit board to test but the nano boot always stuck in the same stage, and here is the boot log.
nanolog.txt (24.3 KB)
It’s very strange that this module works fine in our custom board. And after I reflash it, it still boot stuck.
I used another devkit board it comes same result.
But months ago, these devkit board just works fine
Okay, I just found it maybe the power supply issue.
I use usb-hub to micro-usb to power the board, and when I change the connection by using micro-usb to a usb port, the board can boot normally.
But in dmesg, it shows a lot of printf like this
soctherm: OC ALARM 0X00000001
I wonder if this shows the micro usb power supply is not stable
Hi 854053437,
What’s the Jetpack version in use?
Could you share the result of cat /etc/nv_tegra_release on the devkit?
It seems you hit OC event issue.
Is your board in high temperature or heavy loading?
What’s your power supply in use?
the version is R32(release), revision:7.3
no, I just boot it up, and this information is come out
I use micro-usb to power it up
Is the issue happening after you switch the new power supply?
If so, could you share the detail of your power supply before and after you hit the issue.
Is your micro-USB conneted on 5V/2A or 5V/4A adapter?
Yes
No,it connected on a PC usb, it may be 5V/1A. I used our custom board to powerup there is no problem
Could you share the detail of your power supply before and after?
What do you mean about using “custom board to power up”?
Do you mean using the USB power from your custom board to power up the devkit?
Before，I used micro-usb to a usb-hub to power up the devkit board and it will shutdown halfway. After I used micro-usb to a PC usb port and it can power up normally but with OC ALARM
No, I mean if the module set on our custom board to boot up. there is no OC ALARM
Hi, 5V/2A is the least requirement for USB port power supply. Please use the power source with 2A capability. And also please measure the power voltage level on carrier board to make sure it is correct 5V on board.
okay, thanks!
