U-Boot DFU to MMC1 on BeagleBone Black

Dear All,

I'm trying to do a firmware update on my BeagleBone Black using DFU and nearly getting there:


U-Boot# dfu 0 mmc 1
GADGET DRIVER: usb_dnl_dfu
musb-hdrc: peripheral reset irq lost!

MMC write: dev # 0, block # 63, count 762 ... 762 blocks write: OK
#
DFU complete CRC32: 0xee7826ec
DOWNLOAD ... OK
Ctrl+C to exit ...
U-Boot#


However, the problem is that I'm trying to write to MMC #1 (eMMC), but U-Boot updates MMC #0 (SD card) as it can be seen from the output above.

Is this a bug in U-Boot or I am doing something wrong?

I'm using U-Boot version: u-boot-2013.10-ti2013.12.01 (from TI Sitara SDK 07).

Thanks,
-Tamás
