WebJun 2, 2016 · From this I can see that mtd_ptr->read() have return value -74, but reports into readed that it have 512 bytes readed from mtdblock. But really it is not read data from mtdblock. Additionally I am check mtd_ptr->write() but it correctly report 512 bytes writed and have zero return value. WebJun 2, 2015 · However there is no concept of, e.g., "reading/writing/erasing a partition", these exist separately for NAND and SPIFLASH. So, defining a partition on the SPI NOR is not very useful, except if a generic mtd command (mtd write, mtd read, mtd erase...) is to be created.
