From f10d734f304f333c0c65cc880fd9b3507e08a2ae Mon Sep 17 00:00:00 2001 From: Omar Chebib Date: Thu, 2 Nov 2023 17:05:42 +0800 Subject: [PATCH] change(espcoredump): save RAM space by placing constants in flash All the log messages of espcoredump component used to be in DRAM, which would lower the available RAM space for the user application. Since the cache is always enabled after an exception, constants can be put in flash. --- .../include_core_dump/esp_core_dump_types.h | 9 +++++++-- components/espcoredump/linker.lf | 12 +++++++----- components/espcoredump/src/core_dump_binary.c | 2 +- components/espcoredump/src/core_dump_checksum.c | 16 ++++++++-------- components/espcoredump/src/core_dump_common.c | 2 +- components/espcoredump/src/core_dump_elf.c | 2 +- components/espcoredump/src/core_dump_flash.c | 2 +- components/espcoredump/src/core_dump_uart.c | 14 +++++++------- .../espcoredump/src/port/riscv/core_dump_port.c | 2 +- .../espcoredump/src/port/xtensa/core_dump_port.c | 2 +- 10 files changed, 35 insertions(+), 28 deletions(-) diff --git a/components/espcoredump/include_core_dump/esp_core_dump_types.h b/components/espcoredump/include_core_dump/esp_core_dump_types.h index fa6b8bf8dcd..bb809f9a09c 100644 --- a/components/espcoredump/include_core_dump/esp_core_dump_types.h +++ b/components/espcoredump/include_core_dump/esp_core_dump_types.h @@ -1,5 +1,5 @@ /* - * SPDX-FileCopyrightText: 2015-2023 Espressif Systems (Shanghai) CO LTD + * SPDX-FileCopyrightText: 2015-2024 Espressif Systems (Shanghai) CO LTD * * SPDX-License-Identifier: Apache-2.0 */ @@ -19,7 +19,7 @@ extern "C" { #include "core_dump_checksum.h" #if CONFIG_ESP_COREDUMP_LOGS -#define ESP_COREDUMP_LOG( level, format, ... ) if (LOG_LOCAL_LEVEL >= level) { esp_rom_printf(DRAM_STR(format), esp_log_early_timestamp(), (const char *)TAG, ##__VA_ARGS__); } +#define ESP_COREDUMP_LOG( level, format, ... ) if (LOG_LOCAL_LEVEL >= level) { esp_rom_printf((format), esp_log_early_timestamp(), (const char *)TAG, ##__VA_ARGS__); } #else #define ESP_COREDUMP_LOG( level, format, ... ) // dummy define doing nothing #endif @@ -30,6 +30,11 @@ extern "C" { #define ESP_COREDUMP_LOGD( format, ... ) ESP_COREDUMP_LOG(ESP_LOG_DEBUG, LOG_FORMAT(D, format), ##__VA_ARGS__) #define ESP_COREDUMP_LOGV( format, ... ) ESP_COREDUMP_LOG(ESP_LOG_VERBOSE, LOG_FORMAT(V, format), ##__VA_ARGS__) +/** + * @brief Always print the given message, regardless of the log level + */ +#define ESP_COREDUMP_PRINT( format, ... ) do { esp_rom_printf((format), ##__VA_ARGS__); } while(0) + /** * @brief Assertion to be verified in a release context.
