Rev Pi Connect issue

Post by JoshuaP »

I have not been able to access my Rev Pi connect (PR100274) via its web interface or by USB boot. The lights on the front turn on (PWR, WD and REL all light up green and A1 is a faint red), but I don't see it when scanning the local network ranges 10.56.0.0/16 (company sub-net), 192.168.0.0/16 and 169.254.0.0/16. So I attempted to connect via USB. When running rpiboot from windows 10 I receive a warning that the device is not working and in the device manager it is listed with Unknown USB Device (Device Descriptor Request Failed), This happens on all USB ports and multiple cables.

From the rpiboot.exe console:
Waiting for BCM2835/6/7/2711...
Loading embedded: bootcode.bin
Sending bootcode.bin
Successful read 4 bytes
Waiting for BCM2835/6/7/2711...
Loading embedded: bootcode.bin

After this I attempted to use rpiboot from a second Pi (3b+) and received the same errors. When using verbose mode I receive the following:

$ sudo ./rpiboot -v
RPIBOOT: build-date Jan 14 2022 version 20220111~130126 97f618fc

Successful read 4 bytes
Waiting for BCM2835/6/7/2711...

The dmesg from this event is as follows:

I don't think this is a USB power issue (I assume the Rev Pi doesn't try to pull power via the micro usb on the front).

Any ideas about whats going on here orother things to try?

Dear JoshuaP, thank you very much for the inquiry and the detailed report. This is impressive and detailed. Problems can often be traced back to USB which are manifold. The following checklist can help you to fix the problems in a structured way:

Thanks for the reply Dirk. I was able to make an account and see that page without issue. I have still not been able to interact with the RevPi. I have switched to a short USB cable (that I have used for both power and program other devises so I know the wires are intact), I also tried using different USB ports on the Raspberry Pi (3b+) that I am using to flash the RevPi. The rpiboot software on the 3b+ is build new as of a few days ago so its not an old version.

The new information I have is that when I plug in a screen to the RevPi I don't get a signal (no prompt or anything). Also in contrast to this thread (viewtopic.php?f=4&t=3101&p=10999#p10999) my flashing process never gives me the "Second stage boot server" message, I don't know how relevant that is to my issue.

Hi JoshuaP,

thanks for testing this. The easiest way to see if the flashing works would be to flash another RevPi - or is it the only RevPi yopu have at hand?
Can you use a display and see if its booting up properly?

Unfortunately this is the only RevPi I have. I did try a screen but it did not show any display, and goes into sleep mode so I don't think there is any signal.
