C2000 Flash Kernel B issues on serial port

Other Parts Discussed in Thread: CONTROLSUITE

Hi,

Few questions about Flash Kernel B:

1) Besides byte-by-byte tans receiver, can kernel trans receiver more bytes at one time?

2) Baudrate, we tried 38400, 19200 and 9600, all work. But 115200 and 51600 don't work.

3) Are DFU commands enough for F28377D?

Thanks a lot.

Br, Jordan

    Hi,

    1) In the latest release of controlSUITE the Kernel B has been updated to use the checksum optimization.
    2) The limit is the 10MHz system clock when the boot ROM is running. That is the limiting factor and cannot be changed. If you put the kernel in Flash, and then boot to Flash and copy the kernel to RAM and execute the kernel, you can skip the step of loading the kernel with the ROM bootloader.
    3) Yes.
