Tool/software:
Hi,
I am working on a AM623 based custom board and it is using GPMC NAND as primary booting media and USB as backup boot media.
In our boot mode pin configuration, we are setting the primary boot device as GPMC-NAND and backup device as USB-DFU. Our plan is to initial boot from USB-DFU(loading and run "usb-dfu based" tiboot3, tispl, u-boot) and setup the NAND flash (by loading the nand supported tiboot3, tispl, u-boot and write to the NAND flash).
We used following pin configuration by changing the resistor in the schematic (GPMC-NAND as primary boot media and USB-DFU used as secondary boot media)
B0: 1
B1: 1
B2: 0
B3: 1
B4: 1
B5: 0
B6: 1
B7: 0
B8: 0
B9: 0
B10: 1
B11: 0
B12: 0
B13: 0
B14: 0
B15: 0
But we are facing USB-DFU is not detecting issue while trying initial boot (sudo dfu-util -l shows no device available)
But the same set up is working if I configure primary boot media as EMMC and secondary boot media as USB-DFU.
