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. --- py/objfun.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'py/objfun.c') diff --git a/py/objfun.c b/py/objfun.c index 7e5899456..c586a290a 100644 --- a/py/objfun.c +++ b/py/objfun.c @@ -34,6 +34,8 @@ #include "py/bc.h" #include "py/stackctrl.h" +#include "supervisor/linker.h" + #if MICROPY_DEBUG_VERBOSE // print debugging info #define DEBUG_PRINT (1) #else // don't print debugging info @@ -249,7 +251,7 @@ mp_code_state_t *mp_obj_fun_bc_prepare_codestate(mp_obj_t self_in, size_t n_args } #endif -STATIC mp_obj_t fun_bc_call(mp_obj_t self_in, size_t n_args, size_t n_kw, const mp_obj_t *args) { +STATIC mp_obj_t PLACE_IN_ITCM(fun_bc_call)(mp_obj_t self_in, size_t n_args, size_t n_kw, const mp_obj_t *args) { MP_STACK_CHECK(); DEBUG_printf("Input n_args: " UINT_FMT ", n_kw: " UINT_FMT "\n", n_args, n_kw); -- cgit v1.2.3
