Hello , i want to use QSPI MEMORY(MT25Q128) with STM32L476RE MCU Later, I tried to storage data to above FLASH in Single-SPI MODE(EXTENDED SPI) and That's work is good BUT I hope to storage data USING QUAD-SPI MODE so, tried to below steps

I don't use Interrupt and STM32CUBEIDE HAL LIBRARY 1. SEND ENTER QUAD IO MODE COMMAND(0x35) -> 2. SEND WRITE ENHANCED VOLATILE RESISTER COMMAND(0x65)-> 3. Transmit data 0x7f (This register MSB bit set LOW) because ENABLE QUAD MODE-> 4. SEND WIRTE ENA...
