Seeed Studio XIAO SAMD21

[izenn]

does anyone have any information on how to create an autorcm with the Seeed Studio XIAO SAMD21? It looks like people have done it in the past, but i'm not sure if i need a battery on it or not since from what i understand if the battery is on then the usb-c will not work, but wouldn't the device need power before the switch would power it on? or would the switch always be providing power if it was in rcm mode? I'm trying to avoid opening up and soldering something on

thanks!

Here the guide, but it's made for internal mod on the Switch.

yeah, that was the one i found, but because it is internal, it didn't answer the battery question i have

Why not ask in that thread?

Assuming your goal is just a rcm dongle, it doesn't auto enable autoRCM if you don't have autoRCM on.

These internal boards are just internal RCM loaders and they only work on unpatched Switches.
They do not work on patched Switches like the OLED, Lite or v2 models.

You do not need an external battery for these boards.
The unpatched Switch will go into RCM mode manually if you insert a jig or hack your joycon and press vol - when powering on.
Then the Switch waits for a payload and it will keep waiting for that payload unless you power it off by pressing the power for +15 seconds or so.
When you have autoRCM enabled, the Switch will automatically go into the RCM mode without the need for a jig.
But you need the jig the first time to turn on autoRCM.

The internal RCM loader board also powers up when you turn on the power of the Switch because it is connected to the internal voltage of the Switch.
The Switch almost instantly goes to the RCM mode when you turn it on but it keeps waiting for a payload (data) that must be send over the USB port.
So the internal RCM loader can take its time to boot.
It does not have to be booted before the Switch enters the RCM mode, the Switch will wait anyway.
Once the internal RCM loader is ready, it automatically sends this special payload data over the USB port and this will perform the hack that will enable you to use Hekate and use a CFW after that.

Just like with an external RCM loader, you can plug it in after you powered on the Switch and then turn the RCM loaders power on.

thanks, i have an original unpatched switch with autorcm on, i'm just tired of hooking it up to my laptop when i accidentally let the battery die.

trying to figure out now if i want to build my own or if i should just go out and buy one, the thing that is quite annoying is that i'd have to desolder and replace the usb-c to a male connector. i'd love to get my hands on one of those dragoninjectors but that doesn't look like it will ever happen. are there any recommended sources for a decent loader? from what i understand it does not need to be updatable since hekate would just reload what it finds on the SD if it is newer.
