External Flash downloader shift 1 byte in flash area

[PZamb.2]

Hi

I follow the MOOC tutorial for create the external QSPI loader, my Flash memory is MT25QL128ABB.

The flash is writed but the memory test Fail, with debug inspect there is 1 byte shift from start 0x90000000 (currect 00 01 02 ecc) I read (01 02 03).

I don't know were is the problem , some parameters of flash ?

Other problem thar the flash is not complete written , the MT25Ql128 is 32mB x 4 therefore from 0x90000000 + 0x1000000 but the pattern is wrote 0x9070000

extern QSPI_HandleTypeDef hqspi;

uint8_t CSP_QUADSPI_Init(void);

uint8_t CSP_QSPI_EnableMemoryMappedMode(void);

So perhaps wrong commands, not in the right mode, or a disagreement on address width or dummy cycles. ​

Thak I reduced DUMMY_CLOCK_CYCLES_READ_QUAD 8 and Work , Thank
