• VID = 0x15A2
• PID = 0x0073
Default Strings:
• Manufacturer [1] = "Freescale Semiconductor Inc." (Note that Freescale
Semiconductor is now NXP Semiconductors.)
• Product [2] = "Kinetis Bootloader"
You can customize the USB VID/PID/Strings with the Bootloader Configuration Area
(BCA) of the flash. See
Table 14-3 . For example, the USB VID and PID can be
customized by writing the new VID to the usbVid(BCA + 0x14) field and the new PID to
the usbPid(BCA + 0x16) field of the BCA in flash. To change the USB strings, you need
to prepare a structure (like the one shown below) in the flash, and then write the address
of the g_languages structure to the usbStringsPointer(BCA + 0x18) field of the BCA.
g_languages = { USB_STR_0,
sizeof(USB_STR_0),
(uint_16)0x0409,
(const uint_8 **)g_string_descriptors,
g_string_desc_size};
the USB_STR_0, g_string_descriptors and g_string_desc_size are defined as below.
USB_STR_0[4] = {0x02,
0x03,
0x09,
0x04
};
g_string_descriptors[4] =
{ USB_STR_0,
USB_STR_1,
USB_STR_2,
USB_STR_3};
g_string_desc_size[4] =
{ sizeof(USB_STR_0),
sizeof(USB_STR_1),
sizeof(USB_STR_2),
sizeof(USB_STR_3)};
You can make your own structure of USB_STR_1, USB_STR_2, USB_STR_3:
• USB_STR_1 is used for the manufacturer string.
• USB_STR_2 is used for the product string.
• USB_STR_3 is used for the serial number string.
By default, the 3 strings are defined as below:
USB_STR_1[] =
{ sizeof(USB_STR_1),
USB_STRING_DESCRIPTOR,
'F',0,
'r',0,
'e',0,
'e',0,
's',0,
'c',0,
'a',0,
