I am using the USB HID example from cypress. On the Cy8CKIT-059 (psoc5) it is running fine. I have to use CY8C4247AZI-L485 in a custom board.The system is self powered. I connected D+ D- and VUSB to the pins of the USB connector. I can programm but USB enumeration is not completed. The flow hangs in the while loop
int main(void)
{
uint16_t OUT_COUNT;
uint8_t* response;
CyGlobalIntEnable; /* Enable global interrupts. */
/* Place your initialization/startup code here (e.g. MyInst_Start()) */
/* Start USBFS operation with 5-V operation. */
USBFS_1_Start(USBFS_1_device,USBFS_1_5V_OPERATION); // USBFS_1_3V_OPERATION
while(USBFS_1_bGetConfiguration() == 0x00)
{
/* Waiting for device to be configured */
}
I also tried the 3V operation. I checked the USB configuration and tried all options avaliable
also using P0.0 with a voltage divider connected in parallel to VUSB. What do I miss? How can I get the device running?
Solved! Go to Solution.
