Hello everyone,
I’ve taken over someone’s project in which a Jetson TX2 is used in conjunction with a custom carrier board. On this carrier board some i2c components are present, with which the problems begin.
Among the I2C devices is a GPIO expander (TCA9539) which is very similar to the one on the dev board.
This is where the problems begin. I need the TCA to toggle a output during boot which in turn allows other i2c devices to start up.
To do this, the previous person working on this has made patch files to update the dtb.
However during boot a couple of issues arrive, possibly due to hardware problems on the custom board, see dmesg below:

To prevent issues like timeouts (on i2c busses that I am not currently interested in) I tried decompiling the dtb to dts and removing problematic i2c related things like the 3160000.i2c entry at 0x77. This however does not prevent the issue from popping up.
When scanning the 3160000 bus its terribly slow.
The bus that’s connected to the TCA9539 doesn’t give problems, however the TCA is not showing up when i2cdetect is called.
All i2c timeout issues are solved by plugging the device into the dev board.
So, question 1: Am I investigating the right things or am I missing the point with the direction i’m working?
Question 2: Why are my alterations on the dts files not showing up in the boot sequence after flashing the device?
