@Alex-Kushleyev

Could you verify that this issue is due to missing sensor at U18 port

[Alex Kushleyev]

@Jetson-Nano , the boot issue is not related to the missing U18 (which is a secondary barometer, which was removed from the revised VOXL2 design a while ago (in M0154 revision of the VOXL2 board). The sensor was not used. https://docs.modalai.com/voxl2-onboard-sensors/#barometers

I will double check with the team how to proceed in your case.

Alex

[Jetson Nano]

@Alex-Kushleyev Thank you for your reply. I have a old voxl2 as well as new revised voxl 2, the one not booting is the new one, When I compared it to the old design I didn't find the barometer, but I also had noticed that the new design do not have them, i asked just in case whether it would be the cause. Thank you for clearing the query.

Please discuss with your team and let me know how can I proceed, If you need anymore data from me I can provide it.

Hi @Jetson-Nano,

You have an option to send the board back to use for diagnostics for a fee (if you would like to do that, please fill out the RMA form : www.modalai.com/rma). However, the likelihood for a positive result is not very high because the board and the SoC is so complex and finding micro fractures can be very difficult.

Also, let me clarify why you are able to flash the board in EDL mode, but not boot. When in EDL mode, the majority of VOXL2 SoC is not actually running. You basically have direct USB to FLASH storage access in order to write the low-level partitions. So it might look like the board flashes fine, but when you try to boot into the OS, some issue may prevent the board from booting completely.

There is a way to perform some more diagnostics on your own as well. VOXL2 has a debug console UART port, which is accessible via J3 : https://docs.modalai.com/voxl2-connectors/#j3---legacy-board-to-board-connector-b2b (pins 27, 29, which are unprotected, 1.8V levels).

Even though normally we use a perf kernel which disables prints to the console, when the VOXL2 boots, there are debug messages printed to console before the kernel starts. See example below. It also possible to enable the Kernel messages to console witih a debug kernel, which we could provide if needed (or you could also build it yourself, i can tell you how).

Do you have any add-on boards (like M0130, which has an unpopulated connector with console debug 4-pin J6, which is level shifted to 3.3V). I will see if we have any other options to tap into the debug console.

• https://docs.modalai.com/lte-io-breakout-usb-hub-datasheet/#connector-callouts (look for J6 in the diagram, but it's not populated on the actual board)
• the pinout of J6 on M0130, starting witih pin1 is (3.3V, DBG_RX (in), DBG_TX (out), GND)

We also used to make M0017 but it's EOL. https://docs.modalai.com/m0017/

Here is an example of debug console output on a VOXL2 (M0154) with perf kernel (no prints from kernel itself). You should see what debug prints you get on your damaged board, perhaps it will actually tell you what the issue is.

[Jetson Nano]

@Alex-Kushleyev thank you for reverting back, I will check what you suggested. Try to run diagnostics by myself. I will have to check whether I have M0130, and M0017. I have M0151, will that work.

[Alex Kushleyev]

@Jetson-Nano , no, sorry M0151 does not have the console UART connection at all.

Alex

[Jetson Nano]

@Alex-Kushleyev will the microhard add-on board support it?

[Alex Kushleyev]

@Jetson-Nano , yes M0048 has a serial console port that is labeled in the docs (see diagram: https://docs.modalai.com/microhard-usb-carrier/) . It should work. When in doubt (if you dont see any debug prints), you can test it on a working voxl2 as well.

Alex

[Jetson Nano]

@Alex-Kushleyev sure , i will test it out , thank you for your support. I will get back to you with the result once I test it out.
