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.
Use get top and limit stack functions2019-10-18T09:05:08+00:00Kamil Tomaszewskikamil.tomaszewski@sony.com2019-10-18T09:05:08+00:00urn:sha1:f3151bb6c4adac5ed9cf03d3977ab6d9662c0e05Don't check for corrupt heap too early; Fix QSPI timing2018-12-21T02:28:36+00:00Dan Halberthalbert@halwitz.org2018-12-21T02:28:36+00:00urn:sha1:bce6d124af6531f2d6ad6835546eaa471d0657a0Rework safe mode and have heap overwrite trigger it.2018-12-06T22:24:20+00:00Scott Shawcroftscott@tannewt.org2018-12-06T22:24:20+00:00urn:sha1:6ef863997186e1893cdf19c0e04d0a8a3f33ad9d
This creates a common safe mode mechanic that ports can share.
As a result, the nRF52 now has safe mode support as well.
The common safe mode adds a 700ms delay at startup where a reset
during that window will cause a reset into safe mode. This window
is designated by a yellow status pixel and flashing the single led
three times.
A couple NeoPixel fixes are included for the nRF52 as well.
Fixes #1034. Fixes #990. Fixes #615.
Add stack validity check and raise an error when it happens.2018-12-05T07:26:04+00:00Scott Shawcroftscott@tannewt.org2018-10-23T00:57:28+00:00urn:sha1:7ad2e6ace34a6d417ec1b84472fa409d5451137b
The backtrace cannot be given because it relies on the validity
of the qstr data structures on the heap which may have been
corrupted.
In fact, it still can crash hard when the bytecode itself is
overwritten. To fix, we'd need a way to skip gathering the
backtrace completely.
This also increases the default stack size on M4s so it can
accomodate the stack needed by ASF4s nvm API.
