I am using one RA6M3 EVK & testing QSPI example provided in renesas github.
I am able to write to PAGE 0 using address as below :
#define QSPI_FLASH_ADDRESS(page_no) (uint8_t *) (QSPI_DEVICE_START_ADDRESS + (page_no * PAGE_WRITE_SIZE))
where QSPI_DEVICE_START_ADDRESS = 0x60000000
Now, when i am trying to write to pageno 1, its not able to write to the page whose address should be "0x60000100" since first page should be in range 0x60000000 - 0x6000000FF
