Part Number: PROCESSOR-SDK-AM62A

Team,

I am working on AM62AX Linux EVM(exploring the features).

trying to flash the NAND memory through DFU getting error as 

=> setenv dfu_alt_info ${dfu_alt_info_ospi_nand}

=> dfu 0 mtd spi-nand0
DFU entities configuration failed!
(partition table does not match dfu_alt_info?)
dfu - Device Firmware Upgrade

Usage:
dfu <USB_controller> [<interface> <dev>] [list]
- device firmware upgrade via <USB_controller>
on device <dev>, attached to interface
<interface>
[list] - list available alt settings

=>

mtd list commands gives output as

=> mtd list

    Hi Muthukumar,

    I am routing your query to our U-Boot expert for comments.

    Hello,

    What processor SDK are you using? There were some updates, so 08.06.00.007 should be a good candidate to use.

    Hello,

    dfu command did not work for me. Could you try the following method (attached) and let me know if it works for you, thanks.
