Internal modchip - SAMD21 (Trinket M0, Gemma M0, ItsyBitsy M0 Express) Guide, Files & Support

Notice: I am not receiving notifications for this thread. I didn`t realise people were still posting in it.

Please please accept my apologies if I haven`t replied to tags etc... I have no idea what is happening. I`m subscribed to this thread but I am not receiving notifications. Please inbox me if possible. Or tag me in another thread.

Its amazing that people are still checking all of this out. I thank you for all of the help and support I have received in this thread over this year.

Cheers. Matty.


A video showing a modchip in action. Thank you once again to @metaljay for providing this. This is what you can achieve by fitting a chip!



Section 1. Gather your software.

Get your chip software from THIS THREAD.
Follow the flashing instructions there...




Section 2. Removing USB port and unneeded LEDs. (Adafruit chips only)
  • Next, we need to remove the USB port from the modchip. I recommend a heatgun or a rework station. Heat up until the USB port just lifts off the modchip.
  • Do the same for the LED just to the right of the USB port.
See picture:

You are now ready to fit your device. Proceed to Fitting section.





Section 3. Fitting modchip to your Switch.
New Universal Method. All SAMD-based internal chips. If your chip is not supported and you cannot work it out, PM me.

BUILD YOUR OWN FROM A QFP ATSAMD21E18. Trinket equivalent pins.
Flash Trinket bootloader using OpenOCD via serial pins SWDIO / SWDCLK. Fit a reset switch somewhere... Or going to power / wake (aka method 2). If building for external use, it is good practice to fit a third capacitor between 3V & GND. This is deliberately vague and ambigious, as this needs research and you need to know what you are doing.

Replacement Parts List

Ok... So you have damaged your switch soldering your chip in. Not to worry.

First things first, DO NOT BRIDGE THE CONTACTS HOPING TO REVIVE YOUR SWITCH. With resistors, you may possibly get away with this, but with the capacitors listed below, if you jump these points, you will make a nice short-circuit to the PMIC and / or the M92T36, killing them instantly. Don`t do it.

OK... I`ll list these parts with METHOD 2 & 3 TRINKET PIN NUMBERS and the values of the components they solder to.

TRINKET 3V (POWER SUPPLY) - 2.2uF 0402 size MLCC capacitor. Voltage unimportant as long as it is over 6.3v
TRINKET PIN 2 (POWER ON RESET - goes to pin 5 on M92T36)- 4.7uF 0402 size MLCC capacitor. Voltage unimportant as long as it is over 6.3v
TRINKET PIN 0 (VOL+) - 150R (150 ohms) 0201 Thick Film resistor. 50mW
TRINKET RESET (SWITCH POWER BUTTON) - 150R (150 ohms) 0201 Thick Film resistor. 50mW


I recommend RS components.

FAQ

Q - How do I boot the switch into APX (RCM) mode?

A - You need to short out pin 10 on the right joycon rail to GND with a jig or modded joycon or paperclip (not recommended... Buy a jig you cheap-ass gyppo). Once shorted out, hold down vol+ and power. The switch screen should be off... Plug into your PC and it should recognise a APX device. Well done. You are in RCM.

Q - What glue should I use?
A - Only glue if necessary! Ideally if your soldering is of sufficient quality and your wire is thin enough, you don`t need glue. I use a bit because I am OCD. Anyway, use Epoxy. It`s what I use. Gives you some working time, is solid. Superglue makes a mess DO NOT USE SUPERGLUE. The only thing super about it is how it melts things. Epoxy won`t stick to the shield long-term, so bear that in mind. Pure Acetone will remove epoxy. Acetone tends to remove / melt anything to be warned. CHECK YOUR GLUE WON`T GO CONDUCTIVE OVER TIME - LOOKING AT YOU SCAMSUNG! The combination of heat cycles and absorbing of moisture can turn adhesive into a high-impedance connection!

Q - What size wire should I use?
A - I use AWG40 magnet wire or AWG30 Kynar. AWG40 goes onto components easier... And if you snap it, chances are the wire will snap and not the trace / component.
A2 - You can also use AWG30. I recommend Kynar wrapping wire but any will do. Looks nice, good resistance to elements, tidy. Nothing thicker than AWG30. You are just causing yourself more headaches. Trust me.

Q - Is AWG40 thick enough?
A - Yes. AWG40 is good for around 90mA.

Q - which methods do you recommend?
A - Connect all the straps...

Q - how do you recommend to set it up?
A - Fusee Suite. Search for Fusee Suite or go to link at top of this OP.

Q - My switch is flat and won't turn on.
A - Have you got the charger connected? Disconnect it or your switch won't boot! Boot to a payload (SX loader/Hekate), reconnect charger and leave on the payload menu and charge. Leave for 15 minutes and switch will start normally. It will continue charging one booted.

Disclaimer:
You have only yourself to blame. This voids warranty. This may or may not get you banned from online services. If it does, you got yourself banned. I`m not responsible if you kill your switch / your first-born with any of this in this post. I`m not infalliable. I`m partly senile. Do your own research. Kids, get bill payers permission before you attempt even using a screwdriver.
NUTSHELL: Don`t come having a go at me because you fooked your £300 console up. I`ll do my best to help you though if you do, Just don`t blame me.

IF YOU REQUIRE SUPPORT, IF YOUR CONSOLE ISN`T WORKING CORRECTLY... PLEASE POST A HIGH RESOLUTION PICTURE OF YOUR INSTALL. You might think it isn`t your soldering, but in all cases with the new methods, it is bad soldering. So, please post a picture.


A BRIEF WARNING - PLEASE READ
THIS MOD IS NOT FOR THE FEINT OF HEART. WE ARE SOLDERING TO TRACES AND COMPONENTS ON THE FRONT SIDE OF THE BOARD TO SAVE HAVING TO REMOVE THE BOARD AND SOLDER TO TESTPOINTS. IF YOU ARE STRUGGLING, OR THINK YOU ARE GOING TO STRUGGLE, PLEASE PLEASE SOLDER TO THE TEST POINTS NOTED IN THIS AND OTHER THREADS (YOU WILL NEED TO REMOVE THE MOTHERBOARD). DOUBLE - TRIPLE CHECK EVERYTHING. YOU HAVE BEEN WARNED!!!
Good soldering skills are needed!
A magnifying glass is needed!
Good soldering iron needed - ideally with a 0.3 conical tip. No more than 30w!
SECURE YOUR WIRES PRIOR TO SOLDERING. Stick them down with double-sided tape.
Only use glue if you need to and glue wires after soldering. Don`t glue the solder to the component!
Put the tiniest amount of glue on the PCB mask only. Never on components. Use a cocktail stick for more glue control!!!
Take a look at alternative solder points to get you out of the sh*t if you do rip something off the board
If you aren`t the best at soldering, then think very carefully about connecting to pin 6 capacitor (the one in these new methods). If you rip this pad, you WILL NEED TO REMOVE YOUR BOARD and run from a testpoint.

Quick question, how do we get the files on the TrinketM0? My Trinket only shows up as having 44kb of space on it.

try ejecting it maybe and try again cuz tbh I just reflashed mine to the newest hekate he posted when u press the button do the leds change colour cuz if u press it right it should launch straight to the trinketboot that u just override with the uf2 folder file

weird I got mine like a week ago maybe 2 can`t remember atm moment, I had the same problem when I first tried but then once I pressed the button properly it opened the menu so not sure maybe its broken but I don`t think it would so u the contents of the current file cuz I was reading adafruit the trinket pages and didn't even noticed till I saw the part about reflashing

u still on the discord just wondering cuz don't really want to clutter his forum post

but I have a mistake you to help me because I do not know too much about raspberry
she connects well etelnet he does not see the chip
he says I have a problem on the line14

I asked you if you had a picture of the microsd of your raspberry

Can you post your openocd.cfg? Image of my backup uploading now. This is for pi2 btw. If you want to change, you need to change in openOCD.cfg

Cant seem to get it to go into the boot. Just the normal file system.

do you get 2 red leds when you double press the reset button.

when your in boatload mode the middle led turns green when hook up to pc.

install the drivers again

Hi Guys,

I am new on the NSW scene and hope someone can shed some light on the problem that I am having after installing the trinket accoring to the Method 1 guide in this thread using the SX OS payload.

Basically the battery will not charge anymore and I already read though the complete thread, but couldn't find anyone with the same issue.

So initially I thought the operation was succesfull, although I did have some trouble with the new 3V point. Since it was so small i bridged the bottom and top resistors, but I managed to remove the solder and it seemed all OK after.

However, I did forget to test whether the battery would charge. Each time I managed to coldboot and restart the device into SXOS, but the NSW started to hang at the Nintendo Switch (Horizon) logo after 5 reboots or so and I just couldnt get pass the screen anymore. The battery was somewhere at 10%, so when I put the NSW in the docking station, the power led on the docking station just started blinking fast. Tried it on other charges, but no luck.

Then after removing the back cover and connecting the charger to USB port, the trinket started flashing red.

Checked all the solder points, but they seemed fine. This was the moment when I went into panik mode, thinking I bricked the thing. Decided to unsolder the trinket and cleansed all points with alcohol. It boots into OFW horizon as schould, but it still wont charge the battery. I really hope I haven't bricked the NSW :(

All suggestions are welcome...

I'll start how we normally start

Can you post a pic of your install? As high resolution as possible?

Sounds to me that if you shorted, bridged a connection aka the 3.3v that goes to the Power Ic m92t36
And or resistor,
you may of ruined the charging circuit or Power ic chip,or resistor.
And seen as you have removed the modchip /trinket and removed all connections im guessing im right, you have blown a component, or you have a missing connection to wear you joined your mod chip..

I havent read my outputs with a multi meter, But maybe someone on here can provide you with the information of the components to check and what the readings should be ,

At may also be the bq24193 battery IC,

Like any install or uninstall soldering etc, always check your solder point and or connections..
Have another look at your main board for any missing components, bad solder points bits of solder bridging connections etc..

sound like you have either damage the cap you solder to or the diode near the usb port is pop it's clogs.

check the diode for 5v bottom and 3.2v top

charger_issue_volts.jpg


does the led just blink when it's placed in the dock, that would most likely be the cap you solder to that's the issue.

if I recall correctly I had one with the cap missing and it wouldn't charge or work via the dock, that was the bottom cap 4.7uf if I remember correctly.

Hi Matty, currently there is no install because i removed the trinked, but here are the images:
20180825_182132.jpg


Check this cap here in red, use a multimeter for continuity connect to the bottom of cap towards usb connector, and the pin on the ic connected to the trace under the cap

Looking at that picture tho it looks like you used a tool to cut and you may of grounded your trace or cap

You need to reflow that capacitor that Canna marked.

Use a little flux and clean well. The joint is dry and possibl;y bridged to VCCIN (above it). The cap looks undamaged.

Those little caps can take a fair bit of abuse. I`ve had plenty stuck to the end of soldering irons in the past.

Get a nice joint on that and all will be well.

Ok, measured for continuity bottom side of the cap to, I think you meant the pin on the ic going to the top side of the cap right? There is no continuity. I am not sure I can repair this, since i dont have the proper tools for such small components. Looks I am out of luck.

Ok thanks Matty, Canna. Will reflow the cap and let you know the outcome.
