Hacking Question MODCHIP FITTING

[FR0ZN]

Depends. You can use mattys prebuild uf2 files with modified Hekate, or you can flash it your self with any payload you want using arduino.

I can also recommend this tool here, which gets WAAAAAAAY too little attention.

https://gbatemp.net/threads/samd-fusee-payload-launcher-v2.517731/page-4#post-8280815

Connect your modchip in flashing mode to your PC -> take the CURRENT.UF2 file and paste in the folder of UF2-Splicer -> take your desired "payload.bin" -> let the UF2-Splicer do it's magic and flash the new CURRENT.UF2 to your mochips.

Easy to use and no messing with Arduino etc.

You can use Fusee-UF2 as well in modchip software thread. No conversion necessary. Flash your chip once, forget it forever. Just put payloads on SD.

THX for your work mattytrog

To be clear...

1. Get a brand new Trinket m0 chip
2. put Fusee-UF2 file on it (for ex. "TRINKET_LEGACY3_FUSEE_UF2_V2.UF2")
3. Trinket m0 is done

4. If I already have autoRCM and just want boot direct into CFW, I need the 4-wire Setup
5. put payload.bin on the SD root
6.done

Is this right?

Sorry for asking, but all the Straps/Fittings/Switchboot make me crazy

Yep correct.

Summary:
The simplest fitting is 4 wire... Flash fusee-UF2, enable autoRCM, you are done. Payload goes on SD card (fusee-primary / hekate / whatever)

Thank you, for the fast reply & hopefully i am not a big noob in your eyes start ironing is always a big step for me

Maybe you could prevent a lot of insecurity for the members in your main software thread, when you build in a "Easy Installation" Guide like:

You hate iron? You just want CFW, without other Options? You have a new Trinket m0? You already use CFW?

HERE IS YOUR GUIDE!​

--- Modchip first:
Step 1: Connect your Trinket m0 to your Computer. A new Drive should show up.
Step 2: Open the Drive, and copy this file in it "TRINKET_LEGACY3_FUSEE_UF2_V2.UF2"
Step 3: Your Trinket m0 Modchip is done

--- Switch second:
Step 4: Put your Switch into autoRCM-Mode
Step 5: Put your payload.bin on the SD Card root directory
Step 6: Open your switch, disconnect the Battery and threw the Trinket m0 inside with the 4-Wire Method (3V, GND, DAT- and DAT+)
Step 7: Reconnect Battery, test everything and when its working, build your Switch together

Yep. I know I can improve all my ovwer-complicated threads. And one day, I`ll do it. Soon™.

Use the TRINKET/REBUG with 4 wire though... You could get random reboots of the chip otherwise as there is a capacitive pin exposed that is very sensitive on METHOD3/LEGACY3

good morning...what diagram and uf2 can i use for vol+ power for cfw and power for originalf firmware?

 

[mattytrog]

You need to follow one of my pics in modchip thread depending on which chip you have.

You will need all straps fitting (actually, 5 wires are REALLY needed... 4-wire plus joycon strap), then use Switchboot part 1 (joycon only) for your chip.
