Reboots from here and starts over…

Looks like something goes wrong before CPU gets hang, but need to enable more verbose log.

Please remove the “quiet” in extlinux.conf, reflash the board again and see if more log could be enabled.

Hi @WayneWWW

We found the bug, it was due to a camera driver error where the CAM1_PDWN pin was defined as:
#define CAM1_PWDN TEGRA_MAIN_GPIO(L,6)

It should have been defined as N, 2 for the TX2.

I’m wondering what pin L6 does since it could cause some of my jetson modules to endlessly reboot and others worked fine.

Can you shed some light on that?

Thanks
Lasse

Hi Lasse,

I just checked the pinmux spreadsheet and cannot find L06. Guess it is not configurable.

Could it be reserved for some internal functions? On some tx2s it does nothing and they boot just fine, on other it just hangs after “bootconsole [uart8250] enabled”, it was not fun to debug!

This log has nothing special and nothing to do with the issue here.

bootconsole [uart8250] enabled”

There are other logs but get hidden because the kernel log is disabled by the "quiet"setting in kernel cmdline as I mentioned. Only pr_err is printed out.

It looks like GPIO L.06 is shared with the GP_PWM6 Tegra IC ball and would normally be configured as a PWM signal on the Jetson TX2 SoM. The signal appears to remain on the module and does not come to any of the module external pins. The description from the pinmux sheet is “SOM: SOC_CLDVFS_PWM(PMIC)”. So perhaps it is used for some type of DVFS control in conjunction with the PMIC on the module. Maybe your driver/kernel is changing the pinmux mode of GP_PWM6 from PWM to GPIO and that is causing an issue on the module.
