ModXo: SMOL Boy FAQs
Where can I get firmware for the STM32?
Due to legal reasons, this is only an open-source design. Any firmware will need to either be coded on your own or legally obtained. We will not offer any support for firmware nor will provide any firmware for these devices.
How can I enable the Epimetheus side of my board?
Visit our GitHub for directions on enabling the Epimetheus side of the SMOL Boy.
How can I program my SMOL Boy?
You will need to use a ST-LINK2 programmer and follow the programming guide on our GitHub.
Will this work with X version of XBOX?
The SMOL Boy is compatible with all versions of the original XBOX. Visit our GitHub for installation instructions.
Will X BIOS work??
Yes along as it’s been properly packed. Please visit the ModXo GitHub for more instructions on packing your BIOS.
My SMOL Boy is not booting what could be wrong?
Depending on your XBOX revision it could be a few things. For versions 1.0 - 1.4 make sure your D0 point is either connected to the SMOL Boy or is grounded to a viable ground point. For revision 1.6 make sure your LPC has been rebuilt properly. Instructions can be found on our GitHub.
My LCP and DO are correctly hooked up why won’t my XBOX boot?
This can happen for 2 reasons. Reason 1 D1 is installed backwards. If this happens the RP2040 Tiny will not get any power. Reason 2 R1 - 4, make sure you are using 100ohm resistors and they have a good joint on the SMOL Boy.
Why is my XBOX booting with the fans @ 100% and a flashing orange light on the front panel?
This happens when items are not working properly on the SMBUS (SDA, SCL) or are causing faults on the SMBUS. Please double-check your solder jumpers on the Enable pads.
