Log: ---- Zynq> mtd mtd - MTD Sub-system
Usage: mtd list - show list of MTD devices mtd info - show current MTD device info mtd probe devnum - probe the 'devnum' MTD device mtd erase offset len - erase 'len' bytes from 'offset' mtd write addr to len - write 'len' bytes to 'to' from 'addr' mtd read addr from len - read 'len' bytes from 'from' to 'addr' Zynq> mtd list MTD 1: spi-nor@e000d000 Zynq> MTD 1: spi-nor@e000d000 Zynq> mtd list MTD 1: spi-nor@e000d000 Zynq> mtd probe 0 failing to set MTD device 0 Zynq> mtd probe 1 SPI-NOR: detected s25fl128s_64k with page size 256 Bytes, erase size 64 KiB, total 16 MiB Zynq> mtd info MTD Device 1: s25fl128s_64k Page size: 256 B Erase size: 64 KiB Size: 16 MiB Zynq> mtd list MTD 1: spi-nor@e000d000 (active 1) Zynq> mtd erase 0xE00000 0x100000 MTD: 1048576 bytes @ 0xe00000 Erased: OK Zynq> mw.b 0x100 0xaa 0x100000 Zynq> mtd write 0x100 0xE00000 0x100000 device 0 offset 0xe00000, size 0x100000 MTD: 1048576 bytes @ 0xe00000 Written: OK Zynq> mtd read 0x3000000 0xE00000 0x100000 device 0 offset 0xe00000, size 0x100000 MTD: 1048576 bytes @ 0xe00000 Read: OK Zynq> cmp.b 0x3000000 0x100 0x100000 Total of 1048576 byte(s) were the same
