Hi
I'm testing in my board some resistors, with 1.8k form GND to Bootsel1 and a pull up 47k resistor the processor can enter to usb mode. So, I think that the problem is with the GPIO value at reset.
With the 330 resistor, the CPU enter in USB mode?On Thu, Aug 27, 2009 at 9:29 AM, Adam Wang <adam@qi-hardware.com> wrote:
Hi Carlos,Still enter NAND boot mode.
This board have a Reset S1, What happen when you press the U key and push the reset?
Does cpu work on those KEYOUT1~7 and KEYIN1~7 as default "high" status before it starts to run codes to initial those pins, no matter either nand or usb?
sorry, I don't know
Adam
