TMS320F28388D: USB Bootloader

Part Number: TMS320F28388D

Hi Team,

My customer wants to use usb bootloader of F28388D, same as F2837xD.

in case of F2837xD, when they write 0x5A0C at 0xd00, PC recognize PID and VID. but in case of F28388D,  when they write 0x5AFF at 0xd00, 0xFFFF at 0x0d02, 0xFF09 at 0xd04, 0xFFFF at 0x05, PC recognize PID and VID as 0. and shows unknown device. at this time, address 0x00000002 shows 0x300A so it enters USB boot mode.

They have four questions.

Q1. is it normal that PC recognize PID and VID as 0 under USB boot mode?

Q2. if it's not normal, what should they do to get right PID and VID value?

Q3. if PC gets right PID and VID value, can user use USB_Flash_Programmer that provided for F2837xD?

Best Regards,

Ted

    Q1 - Yes I believe so. This will be the case until the drivers are installed, if my understanding is correct.  Only drivers we have currently are the ones used with F2837xD, which will work with F28388D. ~/C2000Ware_2_00_00_03\utilities\flash_programmers\usb_flash_programmer\windows_driver

    Q3 - Yes you can that.

    Best regards
