Question: What is the difference between Flash Kernel A and Flash Kernel B?

Answer: Type A flash kernels erase the entirety of flash before streaming any data in, whereas Type B flash kernels erase only the required sectors as data is being streamed in. Type B kernels also provide users the choice to erase all or chosen sectors as desired, as a standalone operation. In addition, Type B kernels support a variety of user commands as opposed to Type A kernels which only support an application load command.

Question: What are the first things I should check if the SCI flash kernel does not download?

Answer:

  • One area of the program to check is the linker command file - make sure all flash sections are aligned to 128-bit boundaries. In SECTIONS, add a comma and "ALIGN(8)" after each line where a section is allocated to flash. If using the F28P55x SCI flash kernel, align the flash sections to 512-bit boundaries. Instead of "ALIGN(8)" as mentioned above, modify this to "ALIGN(32)".
  • One other common issue users encounter is that the correct boot pins for SCI boot mode are not used. For example, on the F28004x devices, SCI boot has 4 options for GPIO pins to use. Make sure that the pins for the default option are not being used for something else. If the pins are already used, make sure that another SCI boot option is used, so that it can be connected to another set of pins. Make sure that the SCI kernel project uses this SCI boot GPIO option as the parameter for SCI_GetFunction() as well.
  • When using long cables, use a lower baud rate to get rid of noise.
  • For baud rate and connection issues, try running SCI loopback and echoback examples for the device (you can find these in C2000Ware in the device_support or driverlib folders for your device).
