flexspi_nor_flash read

Hi,

Iam trying to write in to a octal spi flash, and Iam using a MIMXRT1176DVMAA nxp chipset to write in to the flash. But iam facing issues with writing more than 256 bytes in to the flash . But when I use the TI based board iam able to write more than 256 bytes. Is there any limitation , which restricts the flash read and write to 256 bytes using the flexspi API. Please some one help on this .
