Updates in OP...

Hello!
My Trinket is at Switchboot v1.5.0 - Hekate CTCaer v5.0.2
I'm trying to update the uf2 files on my trinket m0.
Every time I try to enter uf2 mode, either by TegraRcmSmash or from within the switchboot menu, the switch disconnects from the pc. Then, I have to do a hard reset to get it to turn back on.
Any help would be appreciated.

Here's the log fie from TegraRcmGUI:
Uploading payload (mezzo size: 92, user size: 928, total size: 67144, total padded size: 69632)...
Smashing the stack!
Smashed the stack with a 0x001f byte SETUP request!
Payload successfully injected
RCM device disconnected

Having to do a hard reset in UF2 mode is normal behaviour.

As for the uf2 drive not being seen? No idea. Try a different port / cable / machine.

I noticed, when I boot to Hekate with a usb attached to pc the screen stays black on the switch. It doesn't go into Hekate or Nyx. Is that normal?
Also, I have used this system in the past.
I've changed ports and no difference. The switch is not recognized after the payload is pushed.
I'll try a different pc once I'm back home.
Thanks for your help!

Hmmm... I`ll investigate right now.

Please update bootloader folder. Download and drag/drop. Overwrite any files if prompted.

This is for black screen issue.

Hekate main in landscape? Good or bad idea? Imho makes bugger all difference.

I personally like it, I recently updated to latest release here and downloaded the new bootloader folder to enable nyx but found the UI doesn't have the switchboot options so am going to disable it. Having this sideways is a nice improvement shy of having nyx with all the options you've added.

 

[mattytrog]

It's only 3 or 4 lines of code.

Reverse framebuffer, swap X and y. Done.

Then just offsets to correct. Ie batt at 720 vert instead of 1280.

Reverse the font too

When updating to the latest version of DUAL-BOOT (modified UF2 bootloader) for Rebug SwitchME, I can't get the bootloader to show up as SWITCHBOOT device on my PC now... It seems to have bricked both the bootloaders on my devices. Do I need to hook it up to a programmer and flash stock bootloader? :/

Hmmm... Shouldn't have bricked. Does the console still go into RCM?

@mattytrog Was able to get a 256KB flash dump of the ns-atmosphere using bossa after using the switchboot update mode menu.

Bossa shows the security bit is set, and region 0 is locked. Any way to unlock this? Bossa refuses to unlock it, erase the flash, or write flash.

The NS-Atmosphere Programmer app is just a modified version of bossa, and is able to erase, lock, unlock, and set the security bit. Of course those functions are hard coded and can't be disabled by the end user without modifying the program.

Guys i dont understanded i have to rename the files to current.uf2 or i only drag and drop the to files ?

Yeah it needs to be done in openocd via swd. Or upload the dump here and I'll take a look.

At91samd chip erase is the command you need in openocd. It will wipe the lot.

You may need to program nvmuserrow too.

Part 1 will change your trinketboot to SWITCHBOOT.

Then uf2 drive will open again. Drag and drop part 2 this time
