1. 确保您的硬件支持较高的擦除速度。检查 SPI Flash 芯片的数据手册，了解其性能指标。2. 检查 SPI...
The descriptions fromdocs.espressif.comare not worded very well and almost sound exactly the same. Is CONFIG_SPI_FLASH_ERASE_YIELD_DURATION_MS the amount of time passed to vTaskDelay() at the end of a call to esp_partition_erase_range()? How is CONFIG_SPI_FLASH_ERASE_YIELD_TICKS any ...

关于FLASH存储器,请参考“常用存储器介绍”章节,实验中FLASH芯片的具体参数,请参考其规格书《W25Q64》来了解。25.1. SPI协议简介 SPI协议是由摩托罗拉公司提出的通讯协议(Serial Peripheral Interface),即串行外围设备接口,是一种高速全双工的通信总线。它被广泛地使用在ADC、LCD等设备与MCU间,要求通讯速率较高的场合...
I am not sure how to address this issue. The core spi_flash_erase_range, that this all depends on, already has a loop to erase sector/block by sector/block, and it uses spi_flash_guard_start() and spi_flash_guard_end() correctly for each sector/block. It seems that the tasks are...
查看Flash算法是否在FLM文件。如果没有在,操作失败。如果在: 加载算法到RAM。 执行Init函数。 查看校验算法是否存在 如果有,加载应用程序到RAM并执行校验。 如果没有,执行计算CRC,将芯片中读取数据出来和RAM中加载应用计算输出的CRC值做比较。 执行Uninit函数。

Spiffs is a file system intended for SPI NOR flash devices on embedded targets. Spiffs is designed with following characteristics in mind: Small (embedded) targets, sparse RAM without heap Only big areas of data (blocks) can be erased An erase will reset all bits in block to ones Writing ...
