spi_flash:erase4K((FLASH_COUNT+1)*4*1024) --清除必须操作
local writeOK_flag02= spi_flash:read((FLASH_COUNT+1)*4*1024,3)
print("writeOK_flag02",writeOK_flag02)
if(writeOK_flag02==" ") thenprint('kong1') end
if(writeOK_flag02=="") thenprint('kong2') end
if(writeOK_flag02==nil) thenprint('kong3') end
if(writeOK_flag02==" ") thenprint('kong4') end
先清除4K,接着读清除地方的3字节。请问读到的是什么?
kong1,kong2,kong3,kong4均没有打拼出来。
