Compute Module 3 not detected for re-flashing

Tue Sep 26, 2017 6:54 am

I'd been doing "re-formating" for my Compute Module 3 (with eMMC), I'm using a Raspberry Pi 3 B to perform the format according to the Official website Documentation.

But the

Code: Select all

sudo ./rpiboot
stops at Waiting for BCM2835/6/7 like forever

Any idea to perform a hardware reset?

:) i'm sorry i haven't a clue! ( or Compute Module 3 ;) )

fyi more rpiboot problems / solutions @ https://github.com/raspberrypi/usbboot/ ... 3Aissue%20 !
& historically
https://github.com/raspberrypi/tools/is ... %20usbboot

perhaps you might find some mention of `hardware reset` methods or more relevent info wrt Compute Module 3 @ usbboot/issues

Im curretly trying to use './rpiboot' with pi0 and piA and have seen abit of 'stops at Waiting for BCM2835/6/7 like forever'

after messing about abit with different cables , adapters
and
rpiboot -d [directory] : Boot the device using the boot files in 'directory'
+ firmware copyed from the fat pertitions of various images
at least in the case of pi0 and piA the firmware version used appears critical to success :!:

If you are using the Official CM3 Development Base Board did you set the Jumper in the correct position ???

Can you see the CM3 in device manger (on a windows PC)?

I seem to have manage to brick a CM3 by interrupting the download at about 10% - this is REALLY worrying as a we must offer OTA updates to our customers in the future!

When you say you reformatted the CM3 I wonder if you have effected something in the memory that needs to be there... but from what I understand this should not happen???
