I'm aware of the top post irritant, nonetheless I employ some discretion on short emails.

I revisit these and it looked like my UHP power wasn't enabled. I thought I did this in the Bootstrap code but apparently not: at91_sys_write(AT91_PMC_PCER, (1 << AT91SAM9263_ID_PIOA) | (1<<AT91SAM9263_ID_UHP)); /* Enable VBus on UHP ports */ at91_set_gpio_output(AT91_PIN_PA21, 1); at91_set_gpio_output(AT91_PIN_PA24, 1); One thing I never understood is that after a power cycle with a usb memory stick plugged in, I always have to start and restart the usb probe to recognize the storage device. This happened in a previous version of u-boot (like 1.2.0) and it's also the case with the current source. Is their a reason for that? Perhaps an inadequate peripheral reset? _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
