To flash the i.Mx6ULL board we are using MFG-tool in windows PC. But while connecting the device with the windows PC, we see the there is no HID detection on tool and also shows error of USB device not recognized in PC. We have checked the BOOT mode, it is as per serial down-loader. And also check continuity for boot mode and USB interface. We have also installed the USB driver but no luck. But some times with the particular USB cables HID gets detected but not regularly. Once or twice out of 10 times.


Please see the attached image, with SNVS =2.99V, R63 not populated, R64 populated and getting voltage value on TP92= 2.73V. As per datasheet SNVS should be in between 2.4V to 3.6V. Even I have checked the all OSC CLK - 25MHZ. CLK looks good too.


Boot Mode


Kindly provide the solution.
