Cannot get in Duet 3 web server after upgrade

@jdumoulin said in Cannot get in Duet 3 web server after upgrade:

I tried three different cables.

try adding a -d in the commandline for bossac - it won't help the flashing succeed but it might give some insight as to why it fails.

and three cables may seem like one should work, but its not been the first time someone on this forum have found the fourth to work. although testing the cable with another device and checking to see if it provides both power and (high speed) data should suffice to rule out bad cabling.

[jdumoulin]

@bearer So all three cables worked because the 4th do anything. I did add -d with one of the other cables. I didnt copy the entire result ...I left out a few hundred identical "readWord(addr=0x400e0c08)=0"

thats not how troubleshooting works

Well the 4th cable didnt make a connection at all. It could not find the device.

This is worth a try:

• Fit the Erase jumper
• Power up the Duet
• Press the Reset button
• Without powering down, remove the Erase jumper
• Try to flash the firmware using Bossa

I did that this morning. Bossa com port did show up. No progress for over an hour now

@jdumoulin From the wiki https://duet3d.dozuki.com/Wiki/Installing_and_Updating_Firmware#Section_Fallback_procedure_Num_3.................

If using Bossa:

Check boxes Erase all, Lock, and Boot from Flash

You screen shot shows no check marks on the erase all or lock (boot from flash is hidden).

Still no love from the Duet

Does it just sit there doing nothing, or does it eventually give an error message?

It just sits there. No error message

[dc42]

I'm sorry, I think there is a problem with the processor on that board. Please ask your supplier to replace the Duet 3.

As bossac on the pi connects, and identifies the cpu could it be worth while trying to lower the baud rate? Seems its fixed at 921600 but code does allow for baud rates down to 1200. But does the SAM7x support lower baud rates? (or does the usb thing make it a moot point?)

[dc42]

I've just found another tool for programming flash memory on a SAME70 at https://github.com/atmelcorp/micro-sam-ba. Unfortunately there is no executable file provided. I'll try building it later today, unless someone else beats me to it.

[A Former User]

Needs to be built for cygwin if to be used on windows; for the pi its just git clone and make, no dependencies to deal with and the default image has the build tools it seems.

Not sure if the last command is needed to get the processor out of boot from ROM mode, can't test it. (and I just realized this was the wrong thread, but if OP has a PI...)

git clone https://github.com/atmelcorp/micro-sam-ba.git
cd micro-sam-ba/
make
./usamba /dev/ttyACM0 erase-all
./usamba /dev/ttyACM0 write /opt/dsf/sd/sys/Duet3Firmware_MB6HC.bin 0x400000
#./usamba /dev/ttyACM0 gpnvm set 1
