Fusee Suite not starting

TL:DR: Trinket starts switch in RCM but won't inject the payload

Hey, I had my trinket working without any problems for over a year. But because of some random issues with my joycons I did a fresh switch setup. I also updated my trinket. But now it only lights up the red power led when starting the switch. The multicolour LED stays off all the time. My switch ends up in RCM mode but the payload isnt pushed (I dont see the SD card missing/ Fusee_Suite bootscreen). I also reflashed the trinket multiple times by pressing the reset button when the switch is booted. I can upload both the first and the second uf2 without any issues. Yet I am unable to get the trinket working. Am I missing something? Or might it be that my trinket has gone defective?

Would appreciate any help or pointers what to try

Hello!

Right... I'm guessing you flashed the new part 1?

Sounds like you only flashed part 1 to me. Do this:

Either hold reset button in(push back cover in on switch) or let it trigger RCM mode, then push a payload and let the console boot normally...

Once booted, let screen go off and you should see a "FUSEE" drive pop up. It's this we are aiming for. You might need to double press the back cover(to enter uf2 mode).

Once you have done this, drag and drop part 2.

Let me know how you get on

I must add that if you are flashing a new part 1, you need to flash a new part 2 as the flash is overwritten.

You can however flash a new part 2 without flashing part 1 again.

Cheers Matty

Thank you for your fast response. Unfortunately I did flash part 1 first and after the drive reappeared I flashed part 2. INFO_UF2 inside the "FUSEE" drive also matches the part 1 UF2 Bootloader c40fc1c SFHWRO Model: Trinket M0 Board-ID: SAMD21E18A-Trinket-v0 But still only the power LED briefly flashes and the switch ends up in RCM.

Should I try a specific old version? Unfortunately I am unaware which Version I previously used

[mattytrog]

You have the Fusee drive. Brilliant. Now you need to choose a part 2.

If you have already drag and dropped a part 2, all you need to do is power the switch down.

The Fusee drive opens up out of courtesy in case you want to flash a "settings.uf2" file, upon a successful part 2 flash.

Kind regards Matty

Also... You have unplugged from pc usb haven't you?

It cannot push a payload while connected to pc, as the pc "kidnaps" the port. Disconnect and try booting

[mattytrog]

Also also... Have a read on the main page about FailsafeRCM. If you have USB strap fitted, that is.

[ghost]

Yeah I did flash part 2 and disconnected the Switch before rebooting. But I just realized that I didnt resolder the optional USB Disconnect strap. Will connect it and report back

[mattytrog]

It isn't mandatory to have it fitted.

Your checklist should thus be:

• All required straps connected(should be as it was working) - OK
• Part 1 flashed, turning Trinket from SWITCHBOOT to FUSEE - OK
• Part 2 flashed - Will open up FUSEE on first boot in case you want a SETTINGS.UF2 on there. If not just power down.
• Unplug from USB, try booting.
• If no boot, eject SD card and try booting again. Does it take you to Fusee main page?
• Also, you dont need to keep VOL+ held. Just hold until it tells you to let go, if you want the menu, or press momentarily if CFW booting.

[ghost]

I flashed part 1 Drive reopened and I flashed part 2 Drive reopened and I disconnected Turned off the switch Powered on and ended up in RCM. I dont see the Fusee main page. Even if I remove the SD Card. And the multicolour LED stays off all the time.

(I then connect it to my pc and inject the payload via TegraRCM to exit RCM and start my switch)

[mattytrog]

OK... If you boot into the Switch console, you double-press the back cover, does it go into UF2(Fusee) mode?

Or hold VOL+ down for about 20 seconds... Any LEDS flashing after 4 seconds or so?

[mattytrog]

The only time I have seen something like this, is when there has been an issue with the USB D+ and D- wires (connected wrong way round). Though Fusee opened - so this cannot be the case.

Part 1 is working, because you are entering RCM. If part 1 wasn't working, RCM wouldnt activate. You don't have autoRCM installed do you from Hekate? This isn't required.

[mattytrog]

If you can boot your Switch (by however means - push payload or whatever) and you can access Fusee drive, I'd just drag and drop part 2 again.

[ghost]

Yes when i double press it see the fusee drive. I just held down volume up. After around 5 seconds it starts a few short flashes followed by a longer flash (All in green). I held it for a few seconds and the pattern repeated itself. But afterwards the power LED stayed on.

After a reboot it isnt still working, but I just realized that both the Power LED and the multiclour LED do a short red flash.

Auto RCM is not activated. I also checked and the switch wont go into RCM when the trinket is disconnected. Also after powering down the switch it is not in RCM. Only once i press the power button it enters RCM

[ghost]

I also tried just reuploading part 2 but the issue persists. And ive redone the soldering at least one time so I am quite sure its not a connection issue (especially because all the Straps for RCM work. And as I can access the FUSEE drive the Data straps should also work

[mattytrog]

Goes into RCM... Brilliant.

A short red flash. Brilliant.

Green flashes... Brilliant.

That means part 2 is successfully flashed. The only problem remaining is why the Switch is not getting the payload. The RED little flash signals "push failure". Its green if successful

If you are in RCM, are disconnected from PC, are seeing the red flash... And seeing green if you hold VOL, your Trinket is working normally.

That leaves the USB D+ and D- wires or pads. Nothing else it can be. Are they good solder joints? Can you get back into Fusee drive if booted to Switch lock screen(then putting screen to sleep?)

[ghost]

Yes I can get back into Fusee drive if booted to the lockscreen and putting the screen to sleep. This worked every time without any issue (Did at least 10 reflashes)

Solder joints also looked fine to me. Data Straps are approx 2 cm long. I already resoldered them before but I can give it another shot. (Still I am confused why they would work when the Switch is booted but dont work when the trinket is trying to inject the payload)

[mattytrog]

Ok... Ill investigate this further. In meantime flash an old part 2 if you like. See if any boot. They should all work

I'm going to commit a possible fix. I think it might be injecting too fast for certain units. I'll be home in next half hour and will do a testing trinket build this evening.

I just flashed the Part_1_TRINKET_PERMA_CFW_Latest.uf2 followed by TRINKET.UF2 in your MODCHIP_LATEST Repo. Now I get the LED flashing when trying to boot that I was used to. But I still end up in RCM. Because even these old files arent working with my switch it seems to me that it is indeed a problem with my switch/soldering and not the code. (I also tried it without a SD Card)

On another note, with this old version if I press vol up after my switch gets stuck in RCM the multiclolour LED blinks red. Am I right to assume that the trinket is trying to reinject the payload but keeps failing? That would mean that it isnt a timing issue either

[mattytrog]

Yes. Red = failure. The failure is either finding RCM(99.999999% likely) or actually pushing the payload. I have changed the RCM seek time to 1 second in this build. Can you try this please? TRINKET.zip

[ghost]

Which part1 should I use? Just the latest one ?

[mattytrog]

yes please

[ghost]

Unfortunately no luck. Still end up in RCM. But now the multicolour LED didnt flash red (just the power LED)

[mattytrog]

OK... Power the unit off and try once more, unless you have tried this. Can you try another version for me?

[ghost]

Already tried it twice but I can try it another time. Also happy to test any other files Edit: Tried it two more times. Same behaviour. Now only the Power LED blinks once

[mattytrog]

Thank-you. I cannot replicate the problem you see... OK Test number 2 [TRINKET_TEST2.zip] << Broken

[ghost]

I dont know if its relevant but after I flashed the UF2 from Trinket.zip the FUSEE drive didnt show up again autmatically. Gonna try the new file now

[mattytrog]

Hang on... I discovered problem... Test 3 coming. Oops.. TRINKET_TEST3.zip .

[ghost]

Okay v2 was the same as v1(from my perspective) With v3 at least the multicolour LED is flashing again. Flashing at the same time as the power LED. But I still end up in RCM (Tested twice)

[mattytrog]

Is it going green at all when you first boot up?

[ghost]

When I press the power button? Then it is just flashing red at the same time as the power LED. Or should I retry holding vol up with the switch booted?

[mattytrog]

Yes please. Also, if you can push a payload via PC (tegraRCMsmash or whatever)... Can you push this and tell me if it works? testpayload.zip

[ghost]

I tried holding vol up 2 times. The first time it did the fast green flashes followed by a single longer green flash. There also was a short red flash after. The second time I tried it I got the same green flashes followed by the same pattern in red

[ghost]

And now it just booted into the stock fw. Did I just disable Chip_RCM?

[mattytrog]

Yes. Thats what the green hold vol+ flashes do

[mattytrog]

just hold vol+ again until the first flash, let go, to trigger ChipRCM

[mattytrog]

Are you able to push the payload I uploaded(testpayload) above?

[mattytrog]

When you disabled ChipRCM, you put your console into dual-boot mode. Its a toggle

[ghost]

I am unable to enable chiprcm When I stop holding vol up whilst it is flashing green it still flashes red afterwards. When I keep holding it it will just continue its green pattern, followed by the red pattern whenever i let go

[ghost]

But whatever gonna try to inject the payload first

[ghost]

Injecting the payload worked. Saw the red Fusee_Suite screen and ended up in hekate

[mattytrog]

OK... In OFW mode, you should be able to get into the FUSEE drive... If you can, flash this... This will re-enable ChipRCM SETTINGS_B_JVU_B1_2_LP.zip

[mattytrog]

And stand by. I'm building another test. I've never ever seen a problem like this before...

[ghost]

ChipRcm is now reenabled. Actually I am just highly confused why it isnt working. Tbh I doubt it is a software bug as it worked before. But I am also confused why rcm, power and file transfer works but the trinket cant push the payload. I just cant wrap my head around it

[mattytrog]

Me neither. Try this. I have removed the vendor ID check in case it has a different vendor ID

TEST_4_TRINKET.zip

[mattytrog]

You are getting the Fusee drive... RCM is being triggered... The switch is unpatched. The LED is blinking red (one blink) - that means it isn't seeing RCM from the Trinket.

[ghost]

Still the same :( I guess I am just out of luck

[mattytrog]

OK... Nuclear option. I'm going to try a build without the RCM check... Stand by...

[mattytrog]

Try this... TEST_5_TRINKET.zip

[ghost]

Still no difference
