Tool/software:
Hello Team,
We are using on the AM62xx-Lp-Evm & used OSPI NAND flash memory (W35N01JWTBAG) windows host. We are trying to Boot & flash the U-Boot images from OSPI NAND flash memory through USB-DFU method.
I took the reference from below link.
Currently am following the below steps.
Two sets of images to be built before flashing to OSPI NAND Flash, one set for USB-DFU boot, another set for flashing to NAND Flash (Nand Flash boot).
First set of images to boot using USB-DFU:
1. Build the bootloader images using default “am62x_evm_r5_usbdfu_defconfig” and “am62x_evm_a53_defconfig” configs files.
2. Load the bootloader images tiboot3.bin, tispl.bin and u-boot.img using the dfu-util from host PC.
The following three commands are used to transfer the U-Boot images from the host to the target:
host> dfu-util.exe -R -a 0 -D tiboot3.bin
host> dfu-util.exe -l
Found DFU: [0451:6165] devnum=0, cfg=1, intf=0, alt=0, name="tispl.bin"
Found DFU: [0451:6165] devnum=0, cfg=1, intf=0, alt=1, name="u-boot.img"
host> dfu-util.exe -R -a 0 -D tispl.bin
host> dfu-util.exe -R -a 1 -D u-boot.img
After the transfer of the third file, stop the EVM from auto-booting by pressing any key in the EVM UART console. At this point, the u-boot starts executing on the target.
At the U-Boot prompt, we are executing below commands.
setenv dfu_alt_info ${dfu_alt_info_ospi_nand}
dfu 0 nand list
dfu 0 nand 0
After Executing the dfu 0 nand list & dfu 0 nand 0 these commands it is showing
=> dfu 0 nand 0
DFU entities configuration failed!
(partition table does not match dfu_alt_info?)
dfu - Device Firmware Upgrade
=> dfu 0 nand list

Please help resolve my issue. I have attached the logs for your reference.
