TMS320F28388D: Troubble on using the USB Boot Option, device is not listed by usb_flash_programmer
After the test worked with my DevBoard, I tried to recreate the test again with one of our prototypes. Unfortunately, the device is not recognized by Windows here.
(See my other Thread on this Topic here in TI-Forum)
Windows cannot read the device description. The difference between my DevBoard and our prototypes is that the DevBoard uses a 20 MHz oscillator and the prototype has a 25 MHz oscillator. I suspect that Windows cannot read the device identification because the USB frequency is not set correctly.
Besides the DevBoard with 20MHz oscillator I also have a DevBoard with a 25MHz oscillator. This board shows the same behavior as my prototype and cannot be found by Windows.
What must be done so that I can find a device with 25 MHz oscillator in USB boot loader mode in Windows?
About quick help I would be very grateful. Is there a possibility to reach the USB boot loader in Windows for devices with 25MHz oscillator without adapting the software? This boot option is interesting for us because it allows us to put software on the device without connecting a JTAG.
