From 8e542251405d780f7aa0d6c9abaa30282dd360d5 Mon Sep 17 00:00:00 2001 From: robert-hh Date: Mon, 25 Apr 2022 13:56:45 +0200 Subject: [PATCH] mimxrt: Format the firmware image to match the new teensy loader. The new teensy loader keeps the file system under certain conditions: - The file size is properly set in the file header. - The header version is 4.3 These changes are implemented here, requiring a backport of fsl_flexspi_nor_boot.c. There is still a problem with the command line version of the teensy loader, which fails on the first attempt. At the second attempt it works. The GUI version of the teensy loader is fine. --- ports/mimxrt/Makefile | 2 +- ports/mimxrt/boards/common.ld | 7 +- ports/mimxrt/hal/fsl_flexspi_nor_boot.c | 53 +++++++++++ ports/mimxrt/hal/fsl_flexspi_nor_boot.h | 114 ++++++++++++++++++++++++ 4 files changed, 173 insertions(+), 3 deletions(-) create mode 100644 ports/mimxrt/hal/fsl_flexspi_nor_boot.c create mode 100644 ports/mimxrt/hal/fsl_flexspi_nor_boot.h diff --git a/ports/mimxrt/Makefile b/ports/mimxrt/Makefile index 6312ecdd8f..6a18879ac5 100644 --- a/ports/mimxrt/Makefile +++ b/ports/mimxrt/Makefile @@ -128,7 +128,7 @@ SRC_HAL_IMX_C += \ $(MCU_DIR)/drivers/fsl_trng.c \ $(MCU_DIR)/drivers/fsl_wdog.c \ $(MCU_DIR)/system_$(MCU_SERIES).c \ - $(MCU_DIR)/xip/fsl_flexspi_nor_boot.c \ + hal/fsl_flexspi_nor_boot.c \ ifeq ($(MICROPY_HW_SDRAM_AVAIL),1) SRC_HAL_IMX_C += $(MCU_DIR)/drivers/fsl_semc.c diff --git a/ports/mimxrt/boards/common.ld b/ports/mimxrt/boards/common.ld index fbc99da3dd..3aaa14c83b 100644 --- a/ports/mimxrt/boards/common.ld +++ b/ports/mimxrt/boards/common.ld @@ -207,7 +207,7 @@ SECTIONS __ram_function_end__ = .; } > m_itcm - __NDATA_ROM = __DATA_ROM + (__ram_function_end__ - __data_start__); + __NDATA_ROM = __RAM_FUNCTIONS_ROM + (__ram_function_end__ - __ram_function_start__); .ncache.init : AT(__NDATA_ROM) { __noncachedata_start__ = .; /* create a global symbol at ncache data start */ @@ -223,7 +223,8 @@ SECTIONS __noncachedata_end__ = .; /* define a global symbol at ncache data end */ } > m_dtcm - __DATA_END = __NDATA_ROM + (__noncachedata_init_end__ - __noncachedata_start__); + __DATA_END = __NDATA_ROM + (__noncachedata_end__ - __noncachedata_start__); + __FLASH_DATA_END = __NDATA_ROM + (__noncachedata_init_end__ - __noncachedata_start__); text_end = ORIGIN(m_text) + LENGTH(m_text); ASSERT(__DATA_END <= text_end, "region m_text overflowed with text and data") @@ -262,6 +263,8 @@ SECTIONS . += STACK_SIZE; } > m_dtcm + _flashimagelen = __FLASH_DATA_END - flash_start; + /* Initializes stack on the end of block */ __StackTop = ORIGIN(m_dtcm) + LENGTH(m_dtcm); __StackLimit = __StackTop - STACK_SIZE; diff --git a/ports/mimxrt/hal/fsl_flexspi_nor_boot.c b/ports/mimxrt/hal/fsl_flexspi_nor_boot.c new file mode 100644 index 0000000000..5786f37e7a --- /dev/null +++ b/ports/mimxrt/hal/fsl_flexspi_nor_boot.c @@ -0,0 +1,53 @@ +/* + * Copyright 2017 NXP + * All rights reserved. + * + * SPDX-License-Identifier: BSD-3-Clause + */ + +#include "fsl_flexspi_nor_boot.h" +extern unsigned long _flashimagelen; +extern unsigned long __etext; + +/* Component ID definition, used by tools. */ +#ifndef FSL_COMPONENT_ID +#define FSL_COMPONENT_ID "platform.drivers.xip_device" +#endif + +#if defined(XIP_BOOT_HEADER_ENABLE) && (XIP_BOOT_HEADER_ENABLE == 1) +#if defined(__CC_ARM) || defined(__ARMCC_VERSION) || defined(__GNUC__) +__attribute__((section(".boot_hdr.ivt"))) +#elif defined(__ICCARM__) +#pragma location=".boot_hdr.ivt" +#endif + + +/************************************* + * IVT Data + *************************************/ +const ivt image_vector_table = { + IVT_HEADER, /* IVT Header */ + IMAGE_ENTRY_ADDRESS, /* Image Entry Function */ + IVT_RSVD, /* Reserved = 0 */ + (uint32_t)DCD_ADDRESS, /* Address where DCD information is stored */ + (uint32_t)BOOT_DATA_ADDRESS, /* Address where BOOT Data Structure is stored */ + (uint32_t)&image_vector_table, /* Pointer to IVT Self (absolute address */ + (uint32_t)CSF_ADDRESS, /* Address where CSF file is stored */ + IVT_RSVD /* Reserved = 0 */ +}; + +#if defined(__CC_ARM) || defined(__ARMCC_VERSION) || defined(__GNUC__) +__attribute__((section(".boot_hdr.boot_data"))) +#elif defined(__ICCARM__) +#pragma location=".boot_hdr.boot_data" +#endif +/************************************* + * Boot Data + *************************************/ +const BOOT_DATA_T boot_data = { + FLASH_BASE, /* boot start location */ + (uint32_t)&_flashimagelen, /* Image size */ + PLUGIN_FLAG, /* Plugin flag*/ + 0xFFFFFFFF /* empty - extra data word */ +}; +#endif diff --git a/ports/mimxrt/hal/fsl_flexspi_nor_boot.h b/ports/mimxrt/hal/fsl_flexspi_nor_boot.h new file mode 100644 index 0000000000..fbb8a574f3 --- /dev/null +++ b/ports/mimxrt/hal/fsl_flexspi_nor_boot.h @@ -0,0 +1,114 @@ +/* + * Copyright 2017 NXP + * All rights reserved. + * + * SPDX-License-Identifier: BSD-3-Clause + */ + +#ifndef __FLEXSPI_NOR_BOOT_H__ +#define __FLEXSPI_NOR_BOOT_H__ + +#include +#include "board.h" + +/*!
