Posted on May 17, 2011 at 09:53I was having a LOT of problems with an Unstable USB when coming out of a HW Reset, not a Power Up Reset
This solved a lot of problems
Don't forget to be in disabled IRQs
This and other like it needs to be RIGHT after main or be done in Assembly and placed in 91x_init.s
There looks like a LOT needs to be in 91x_init.s
See Timer 0 - 3 problems that are now solved by doing a TIM_DeInit(), this needs to be in 91x_init.s
// ************************************************
// A system reset does not reset the USB registers.
// ************************************************
void USB_DeInit(void)
{
_SetCNTR(0x0003);
_SetISTR(0x0000);
_SetDADDR(0x0000);
_SetBTABLE(0x0000);
}
