I’m having trouble downloading software to a cc6ul 1GB processor through the USB port.

I did my initial SW work with a cc6ulsbc with the 256MB version of the processor. With that, everything worked fine. I am using linux-dey version 2.2-r3.3.

Now I have a custom board with the 1GB processor. The connections are somewhat different comapred to the SBC, but both the USB terminal and the USB device connectors are identical. And the terminal works fine, but for soem reason I am unable to copy software to the processor.

Before powering on the board, I ground BOOT\_MODE1. The USB device is recognized correctly:  
[3314150.869378] usb 1-1: new high-speed USB device number 59 using ehci-pci  
[3314151.228434] usb 1-1: New USB device found, idVendor=15a2, idProduct=007d  
[3314151.228437] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0  
[3314151.228439] usb 1-1: Product: SE Blank 6UL  
[3314151.228440] usb 1-1: Manufacturer: Freescale SemiConductor Inc  
[3314151.400800] hid-generic 0003:15A2:007D.0009: hiddev0,hidraw1: USB HID v1.10 Device [Freescale SemiConductor Inc SE Blank 6UL] on usb-0000:02:03.0-1/input0

Then I try to copy u-boot to the processor with imx\_usb from the sdk, with conf files from etc/imx-loader.d/, but imx\_usb is unable to copy the image:

Any ideas on what could be wrong?
