Hacking SAMD Fusee Payload Launcher V2

[electronrancher]

Just a note for the folks who have been on the Tindie waitlist - I'm really sorry that it's been some weeks now, I kept pushing it back as I was going back and forth with the fab house to try to optimize the PCB cutout. I think I've got it about as good as it can be, so no more need to wait.

Got more chips on the way, and I will do a build this week - should be up Thursday or Friday!

Update: Wednesday's and Thursday's builds are sold out, I'll cook up another 10 or 15 tonight. BTW - If you would like to place an order from outside the US, you can just PM me. It will be a lot easier than Tindie, as they don't have a shipping solution so I have to type it all in to USPS anyway lol.

Also, all new boards will be shipping with hekate v4.2, and a zip file is posted on the front page of this thread if you want to update.

@mattytrog I ping you here since it's actually about these payloads. I noticed that Electronranches payloads keep the unit flashing until the payload is read. While I need to powercycle my chip with your payload for example. Is it a bug or the intended purpose since your payloads support more chips sort of speak?

It is an intended feature. For modchips.. If you look in the chainloader thread, you will see some dongle builds. Now I'm not sure which bootloader electronranchers board uses, but if it is a trinket, you can use the R4S version. Or I can support it independently. I just need the pinouts for buttons and LEDs. Then it's trivial to set the code switches in my source and build a fresh one of none of the existing versions work well enough

Ah okey! There are so many things in the threads it's hard to keep check. I guess the R4S should work since it's probably the same unit.

Edit: in fact, I am adding a dongle mode. There is going to be that much stuff in this bloody samd launcher... Should give it a name and version numbers lol

 

[electronrancher]

Dongle mode!

Hi @linuxares, I don't use a timeout in my code because I expect the user will power up and fiddle around a bit before being ready to launch. @mattytrog is supporting all sorts of boards, including internal chips that only need to be on for a few seconds - hence, he sets a timeout in his standard builds of ... maybe 10 seconds? I forget

Also, the SAMD board pinout is similar to trinket in terms of buttons, but without the dotstar LED. I just use the activity LED on digital 13, which is also trinket compatible.

@electronrancher you don't happen to have your original files? I think I've bricked my dongle by trying unsupported UF2 files. It's called SWITCHBOOT now and UF2 flashing doesn't help.

EDIT: Fixed! Now I'm trying to resolder the USB-C port that is loose (it came completetly off after I pulled it out of my Switch.
EDIT2: Worked two times, then it died completely. No idea if it's a short or not but I think the traces on the USB got ripped anyway when the port came completely off. I think it's the shell that causes the biggest problem to be honest.

Hello,

I tried updating my dongle with hekate 4.10.1 and it does not seem to work (no blinking blue light after flashing). All older versions worked, and obviously rolling back to 4.9.1 works.

I am sure that the .bin is correct because it works as reboot_payload.bin from atmosphere.

Am I missing something?

Looks like not as cheap soldering.

Honestly the soldering on your provided images are nice and neat. Looks solid.

Please stop revive old threads like this.

Would this work on a tiny2040 microcontroller since it has the same memory, sram and processor?

Not sure if that fall under SAMD21, as for the switch you need an unpatched unit to use fusee gelee exploit.

It is not part of that list , I mean he can look through Mattytrog github, I don't think there is an one for tiny2040.
