2.2 Customizing the Boot Selection Table

Each C2000 device has a factory set default boot selection table that contains boot mode options available on an unprogrammed device. The default number of boot mode selection pins determines how many options are available in the default table. The latest devices use two boot mode selection pins and hence have four default boot modes selectable in Table 2-2.

Table 2-2 Default Boot Options Table Comparison
Device Default Boot Table Options (unprogrammed device) All Available Boot Modes Comments
F2833x
  • 0. SCI boot (No ADC calibration)
  • 1. RAM boot (No ADC calibration)
  • 2. Flash boot (No ADC calibration)
  • 3. Check boot (loop) mode

 Boot modes other than those in default table can be accessed either through emulation boot mode or standalone boot mode. In standalone mode get boot mode is first selected using BMSP and get boot reads the boot mode selection programmed in OTP

 Boot modes other than those in default table can be accessed either through emulation boot mode or standalone boot mode. In standalone mode get boot mode is first selected using BMSP and get boot reads the boot mode selection programmed in OTP. For dual core devices all boot modes are available on both CPU1 and CPU2 except USB boot which is available only on CPU1

 Boot modes other than those in default table can be accessed either through emulation boot mode or standalone boot mode. In standalone mode a custom boot mode table has to be programmed in OTP. For dual core devices C28x CPU2 and CM core are booted through IPC boot command from C28x CPU1. CPU2 and CM core only support flash, wait, RAM, secure flash, user OTP and IPC message copy boot modes. CPU1 does not support User OTP and IPC message copy boot modes

Previous to F28004x devices, the 4th boot mode entry in the default boot table was get boot mode. The get boot mode read a programmable OTP value which decided the boot mode selected. After F28004x, when programmed, the whole boot mode selection table is customizable. Depending on the number of boot mode selection pins (0, 1, 2 or 3) enabled on the device, the custom boot selection table can have 1, 2, 4, or 8 boot mode options available. This custom table replaces the default factory table, so instead of parallel boot, for example, tied to boot option 0, this can now be set to any boot mode such as flash or CAN boot. This table is setup by configuring the 64-bit BOOTDEF memory location in user-configurable DCSM OTP. Each byte represents a specified boot mode.
