From 7d8dac9211dab92d750a0351335b4ad3fffc05e2 Mon Sep 17 00:00:00 2001 From: Scott Shawcroft Date: Wed, 8 Jan 2020 20:32:45 -0800 Subject: Refine iMX RT memory layout and add three boards 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. --- lib/tinyusb | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'lib/tinyusb') diff --git a/lib/tinyusb b/lib/tinyusb index dda4c9a94..1f95f439e 160000 --- a/lib/tinyusb +++ b/lib/tinyusb @@ -1 +1 @@ -Subproject commit dda4c9a94b509238faa7b5ab5b9464c1d2e63ff0 +Subproject commit 1f95f439e11f519e69d75a4a8b7b9f28eaf5060e -- cgit v1.2.3
