Hi, I have a problem with production Nano module. It programs and works fine on a development board from an Auvidea company, but won’t boot on our carrier board. There are similar topics to this, but my case is different in that there is no output on the console at all.
The carrier board was designed according to the design guide and available schematics. I am attaching the power sequence. SYS_RST signal looks fine (goes high about 40ms after POWER_EN), but that’s it. The module doesn’t wake up, the power LED (GPIO4) doesn’t light up, there is nothing on the HDMI output, and nothing on the UART2 (TX is low all the time). The module’s power consumption is initially zero, then spikes at ~1A when raising POWER_EN, and then it settles at 0,4A half a second later, and doesn’t change any more. Nothing changes if I pull POWER_EN down afterwards.
On the screenshot there is PWR_BTN pulse visible, but I also tried without it, and there is no difference.
The 5V supply is stable (10A capability), and all the required caps are mounted near the module. I have measured the supply stability, and there is only a 60mV dip when the POWER_EN goes high (measured directly at the module edge connector pads).
I desoldered almost everything that is connected to the module, and might interfere, and I am out of ideas.
Can anyone tell what could be the reason the module behaves like that?
Does the module require some specific signals or connected peripherals to boot properly?
Turns out the FORCE_RECOVERY input must be left floating without any pulls. I had a pullup resistor to 1,8V, and it started booting after I have removed it. But I have a second piece of the board, which still does not boot after removing the resistor (with the same module).
The power signals are the same as before. This time the console TX goes high, but still no data appears on it.
I’m still open to ideas what might be the reason for the board not boot at all.
The Force_Recovery is a strapping pin and latched during PMIC_RESET raising, Xavier will boot up into recovery mode for testing or firmware update through USB0 port, The system power is about 0.4A during recovery mode, and you could see a NVIDIA USB device when connect USB0 to host PC, Xavier is acted as USB device.
Would you please check if it boot into recovery mode by checking USB device present on host PC?
I cannot test the USB device, because I have an error in the the USB hardware design on the board. Is there any other way to test if the board is in recovery?
I measured the FORCE_RECOVERY pin on the board without the module inserted, and it’s not connected to anything, so the module should not be in the recovery mode. Are there other strap pins, that I should be careful about?
So, You have 2 carrier boards with same design, One can work after remove the pull up on Force_recovery, Another one have problem? is there pin damage on the board to board connector? Is the power consumption like the data in recovery mode? No other strapping pin on module.
Essentialy yes. The were some differences in the number of level converters soldered for UARTs and I2C, but I just made them identical, and the result is still the same.
One interesting thing though. I had one unprogrammed Nano module, and when have I powered up the board with it inserted, it seemed to have worked as expected - MOD_SLEEP went high after POWER_EN has been driven high. After the module has been programmed in a third-party carrier board, MOD_SLEEP never goes high now on the faulty board.
All 3 modules I have work fine on the working board.
I also noticed the 5V supply on the module drops by ~100mV when POWER_EN goes high. Can that prevent proper booting? (It’s the same on the board that works, so I think it shouldn’t).
The VDD_IN operation range is 4.75v~5.25v.
MOD_SLEEP is a GPIO pin to enable HDMI 3.3V power. It should doesn’t matter.
Please capture Force_Recovery, SYS_RST* and SDMMC4_CLK/R40(on module) during power on.
Checking if anything pull Force_Recovery to low during SYS_RST* rising.
SDMMC4_CLK is emmc clock, Tegra will send out this earliest signal when it boot up after SYS_RST*(PMIC_RST*)
There is no low pulse on the FORCE_RECOVERY.
There is nothing on the SDMMC4_CLK, if I’m measuring it correctly. If not please tell me which point should I measure the signal on.
I managed to fix the USB hardware, and the APX USB device shows up in the system if the FORCE_RECOVERY is shorted to ground during power on.
But if the FR is left floating during power on, the device does not show up in the Device Manager, thus the module is not in the recovery mode. I suppose it hangs somewhere. How can I find out where and why?
There is nothing on the UART. The line just goes to 1.8V and stays there. Flashing starts, but an error occurs right at the beginning. Here is the log:

The way of flash.sh was too complicated in my setup, so I went for desoldering components from the board. It came out that the I2C2 level shifter was faulty or badly mounted, and it was forcing 2,7V on the I2C rails.
Thanks for the help.
