From e3d473bf429bd254b53550ebcbbb0d389b49240c Mon Sep 17 00:00:00 2001 From: Sergey Gavrilov Date: Wed, 8 Feb 2023 07:41:22 +0300 Subject: [PATCH] [FL-2435] SD over SPI improvements (#2204) * get rid of BSP layer * sector_cache: init in any case * new sd-spi driver: init * Delete stm32_adafruit_sd.c.old * Delete spi_sd_hal.c.old * Storage: faster api lock primitive * Threads: priority control * Flags: correct error code * Spi: dma mode * SD-card: use DMA for big blocks of SPI data * Fix wrong SD_TOKEN_START_DATA_MULTIPLE_BLOCK_WRITE value * do not memset cache if it is NULL * remove top-level timeouts * sd hal: disable debug * Furi HAL: DMA * Furi HAL RFID: use furi_hal_dma * Furi HAL DMA: tests * Furi HAL DMA: docs * rollback "Furi HAL RFID: use furi_hal_dma" * 4 channels taken from DMA manager for core HAL. * Furi HAL DMA: live fast, die young * RPC tests: increase message buffer * SPI HAL: use second DMA instance * sd hal: new CID getter * SPI hal: use non-DMA version if kernel is not running * IR hal: generalize DMA definition * storage: add CID data to sd info * RFID hal: generalize DMA definition * SUBGHZ hal: generalize DMA definition. Core hal moved to DMA2. * Storage: small optimizations, removal of extra mutex * Storage: redundant macro * SD hal: more timeouts * SPI hal: DMA init * Target: make furi_hal_spi_dma_init symbol private * Update F18 api symbols Co-authored-by: Aleksandr Kutuzov --- applications/debug/unit_tests/rpc/rpc_test.c | 2 +- applications/services/storage/storage_cli.c | 21 +- .../services/storage/storage_external_api.c | 9 +- applications/services/storage/storage_glue.c | 18 +- applications/services/storage/storage_glue.h | 3 - .../services/storage/storage_message.h | 3 +- .../services/storage/storage_processing.c | 39 +- .../services/storage/storage_sd_api.h | 10 + .../services/storage/storages/storage_ext.c | 33 +- .../scenes/storage_settings_scene_sd_info.c | 21 +- firmware/targets/f18/api_symbols.csv | 6 +- firmware/targets/f18/furi_hal/furi_hal.c | 1 + firmware/targets/f7/api_symbols.csv | 6 +- firmware/targets/f7/fatfs/sd_spi_io.c | 877 +++++++++++++ firmware/targets/f7/fatfs/sd_spi_io.h | 157 +++ firmware/targets/f7/fatfs/sector_cache.c | 5 - firmware/targets/f7/fatfs/spi_sd_hal.c | 98 -- firmware/targets/f7/fatfs/stm32_adafruit_sd.c | 1113 ----------------- firmware/targets/f7/fatfs/stm32_adafruit_sd.h | 245 ---- firmware/targets/f7/fatfs/user_diskio.c | 36 +- firmware/targets/f7/fatfs/user_diskio.h | 2 +- firmware/targets/f7/furi_hal/furi_hal.c | 1 + .../targets/f7/furi_hal/furi_hal_infrared.c | 121 +- firmware/targets/f7/furi_hal/furi_hal_rfid.c | 46 +- firmware/targets/f7/furi_hal/furi_hal_spi.c | 231 +++- .../targets/f7/furi_hal/furi_hal_subghz.c | 49 +- firmware/targets/f7/src/update.c | 4 +- .../targets/furi_hal_include/furi_hal_spi.h | 20 + furi/core/event_flag.c | 2 +- furi/core/thread.c | 9 + furi/core/thread.h | 12 + 31 files changed, 1539 insertions(+), 1661 deletions(-) create mode 100644 firmware/targets/f7/fatfs/sd_spi_io.c create mode 100644 firmware/targets/f7/fatfs/sd_spi_io.h delete mode 100644 firmware/targets/f7/fatfs/spi_sd_hal.c delete mode 100644 firmware/targets/f7/fatfs/stm32_adafruit_sd.c delete mode 100644 firmware/targets/f7/fatfs/stm32_adafruit_sd.h diff --git a/applications/debug/unit_tests/rpc/rpc_test.c b/applications/debug/unit_tests/rpc/rpc_test.c index 5b52df2f..76acf6be 100644 --- a/applications/debug/unit_tests/rpc/rpc_test.c +++ b/applications/debug/unit_tests/rpc/rpc_test.c @@ -89,7 +89,7 @@ static void test_rpc_setup(void) { } furi_check(rpc_session[0].session);

How to use this driver: --------------------------- - - This driver does not need a specific component driver for the micro SD device - to be included with. - -2. Driver description: ---------------------- - + Initialization steps: - o Initialize the micro SD card using the BSP_SD_Init() function. - o Checking the SD card presence is not managed because SD detection pin is - not physically mapped on the Adafruit shield. - o The function BSP_SD_GetCardInfo() is used to get the micro SD card information - which is stored in the structure "SD_CardInfo". - - + Micro SD card operations - o The micro SD card can be accessed with read/write block(s) operations once - it is ready for access. The access can be performed in polling - mode by calling the functions BSP_SD_ReadBlocks()/BSP_SD_WriteBlocks() - - o The SD erase block(s) is performed using the function BSP_SD_Erase() with - specifying the number of blocks to erase. - o The SD runtime status is returned when calling the function BSP_SD_GetStatus(). - -------------------------------------------------------------------------------*/ - -/* Includes ------------------------------------------------------------------*/ -#include "stm32_adafruit_sd.h" -#include "stdlib.h" -#include "string.h" -#include "stdio.h" -#include -#include "sector_cache.h" - -/** @addtogroup BSP - * @{ - */ - -/** @addtogroup STM32_ADAFRUIT - * @{ - */ - -/** @defgroup STM32_ADAFRUIT_SD - * @{ - */ - -/* Private typedef -----------------------------------------------------------*/ - -/** @defgroup STM32_ADAFRUIT_SD_Private_Types_Definitions - * @{ - */ -typedef struct { - uint8_t r1;
