HAB events when using imx_usb_loader

[andrelabelle]

Hi,

If I load my image from SPI-NOR I don't get HAB events.

If I switch to the serial loader boot mode and load the same image I get HAB events.

When I compare the RAM data of the working u-boot image with the non-working image I see the imx_usb_loader version has its IVT dcd and boot_data fields cleared.

working:

177ff400: d1 00 20 40 00 00 80 17 00 00 00 00 2c f4 7f 17    .. @........,...

177ff410: 20 f4 7f 17 00 f4 7f 17 00 10 86 17 00 00 00 00     ...............

non working:

177ff400: d1 00 20 40 00 00 80 17 00 00 00 00 00 00 00 00    .. @............

177ff410: 00 00 00 00 00 f4 7f 17 00 10 86 17 00 00 00 00    ................

Has anybody experienced this issue? Has anybody worked around this issue?

Thanks,

Andre

I'm using imx_usb_loader master branch f96aee286ea17c832b7ec922dd76842deb5ce299 and a nitrogen6x development board.
