mode where 1 to 256 bytes of data can be programmed into the memory with one command. Pages can be erased in groups of 4Kbyte sectors, 32Kbyte blocks, 64Kbyte blocks, and/or the entire chip. The uniform sectors and blocks allow greater flexibility for a variety of applications requiring s...

一次擦除大小可以为16页(4KB)、128页(32KB)、256页(64KB)或者全擦除。 W25Q64JV有2048个可擦除扇区(sectors),或者可以说有128个可擦除块(blocks)。关系 1 Block = 16sectors;1 sector = 4KB,所以算起来能达到8M-byte。 编程即写数据,由于Flash的特性,只能从1编程0,所以写数据之前Flash里面的数据不是0xFF...

编译下载,ccs 会提示 erasing flash sectors. 下载完成后,将 DSP 芯片断电后再上电,观察程序是否仍然还能运行。 这篇文章同样发布在mengsheng.me 注意事项 如果dsp 使用 usb 扩展坞供电,可能无法正常从 flash 启动。
#define FLASH_TYPEERASE_SECTORS 0x00U /* 扇区方式擦除 */ #define 1. 2. Banks 用于选择要擦除的BANK,或者两个BANK都选择: #define FLASH_BANK_1 0x01U /* Bank 1 */ #define FLASH_BANK_2 0x02U /* Bank 2 */ #define 1. 2.
A system of Flash EEprom memory chips with controlling circuits serves as non-volatile memory such as that provided by magnetic disk drives. Improvements include selective multiple sector erase, in which any combinations of Flash sectors may be erased together. Selective sectors among the selected com...
