之前我们用的W25Q80BL,工作在40Mhz QIO ,系统运行正常
本次生产时,供应商反馈W25Q80BL要停产了,后续供货是W25Q80DV,测试时我们发现,在频繁地FLASH读写时(工作在40Mhz QIO),系统经常崩溃
reset info:2,x
或
reset info:3,x
我们仔细对比了两款flash,发现他们的特性上:
1,电压要求一样;
2,工作最大频率DV更高(可达104Mhz)
3,Tpuw(Time Delay Before Write Instruction)特性不一样,DV 的最小值为5ms,BL的最小值为1ms,这个是否会有影响。
esp官方对这款FLASH的支持时如何的?有方法可以解决频繁读写FLASH时,系统崩溃的问题吗?
FLASH芯片从W25Q80BL换为W25Q80DV后,系统运行经常崩溃
