supervisor: add a new WATCHDOG_RESET safe mode reason

2020-05-27T03:28:49+00:00

This mode will be used if the board is reset due to the watchdog expiring. Signed-off-by: Sean Cross

Refine iMX RT memory layout and add three boards

2020-01-18T01:36:08+00:00

Introduces a way to place CircuitPython code and data into tightly coupled memory (TCM) which is accessible by the CPU in a single cycle. It also frees up room in the corresponding cache for intermittent data. Loading from external flash is slow! The data cache is also now enabled. Adds support for the iMX RT 1021 chip. Adds three new boards: * iMX RT 1020 EVK * iMX RT 1060 EVK * Teensy 4.0 Related to #2492, #2472 and #2477. Fixes #2475.

Supervisor: move most of systick to the supervisor

2019-11-18T17:01:23+00:00

This code is shared by most parts, except where not all the #ifdefs inside the tick function were present in all ports. This mostly would have broken gamepad tick support on non-samd ports. The "ms32" and "ms64" variants of the tick functions are introduced because there is no 64-bit atomic read. Disabling interrupts avoids a low probability bug where milliseconds could be off by ~49.5 days once every ~49.5 days (2^32 ms). Avoiding disabling interrupts when only the low 32 bits are needed is a minor optimization. Testing performed: on metro m4 express, USB still works and time.monotonic_ns() still counts up

Rework safe mode so we can trigger on all resets

Update `on_next_reset` for new safe mode.

Fix crash when getting board.SPI outside the VM

2019-04-06T02:06:37+00:00

If one of the default pins was already in use it would crash. The internal API has been refined to allow us to get the value without causing an init of the singleton. Fixes #1753

Enter safe mode when an allocation is attempted on an uninitialized heap.
