Reset pin not connected #14

Closed xobs closed 6 years ago

xobs commented 6 years ago

The /RESET pin (pin 7 of the MCU) is not made available. This is an issue when working on the bootloader.

Ordinarily, the system relies on being able to send a JTAG reset. This is fine if the MCU isn't locked up. However, if the MCU crashes then it is impossible to reattach gdb without a reset.

In order to develop on the bootloader itself, /RESET should be brought out to a pad.

This should be in tomu-hardware, though it does affect the development of tomu-bootloader.
