Hi,
I have following two questions about the serial programming using bootloader:
- So far as I have understood, the basic steps for F28069 are: Is my understanding correct?
- Set corresponding pins to SCI BOOT mode and reset the MCU
- Synchronize baudrate (socalled auto-baud) by sending ASCII 'a' or 'A' and receiving the same character if succeed
- Send a flash kernel with robust functions (similar to the example 'f28069_flash_kernel__v151' in TI library) in the correct 8-bit format.
- Erase the corresponding sections of flash, send the real application firmware, depending on the above robust kernel.
- Set to normal mode and reset. Done.
- at the first auto-baud step I found that the valid baudrates are (from 38400 on) 38400, 57600, while 56000, 115200 or 500000 don't work. Is it possible to set the baudrate to a fixed value for example 500000 and make it alos valid?
Best regards,
W.L.
