Hi,

I have a question about the nand flash driver. Whether the nand_ecc_ctrl->read_page/write_page can do more than one page operation? or is there any interface for nand_ecc_ctrl to let driver support multi-page read/write?

Since in that case I can do some optimization in multiple pages read/write operation. for example: prepare the buffer for next page.

Best Regards,
Josh Wu

I think OneNand driver does multi-page I/O, check it.
