Hi Patrick,
Add DFU backend for MTD device: allow to read and write on any MTD device (RAW or SPI)
For example :
set dfu_alt_info "nand_raw raw 0x0 0x100000" dfu 0 mtd nand0
This MTD backend provides the same level than dfu nand
^^^^^ - shouldn't there be "functionality" or such?backend for NAND in RAW mode and sf backend for NOR; So it can replace booth of them but it can also add support of spi-nand.
If I understood correctly - it allows reading "raw" data from MTD device - NAND, SPI-NOR and SPI-NAND?
Yes, "all MTD devices" : NAND, SPI-NOR, SPI-NAND
My message wasn't clear except if you know the driver organization, I update it in V2
drivers/mtd/raw drivers/mtd/nand drivers/mtd/spi
and potentially also ONENAND als o (not tested) with drivers/mtd/onenand
set dfu_alt_info "nand_raw raw 0x0 0x100000" dfu 0 mtd spi-nand0
The backend code is based on the MTD command introduced by commit 5db66b3aee6f ("cmd: mtd: add 'mtd' command")
