Other Parts Discussed in Thread: TMS320F28335, C2000WARE
I have developed a tool to be able to download a hex file to the F2808 (on a dock kit) via a Innomaker tool.
When I load the hex file via an update() method I created (using the Flash API), I can upload and burn the flash as expected indicating the hex file is good for loading, ( I have 2 hex files - 1 with 1/2 sec LED blinking and 1 with 1 second blinking. Loading either hex file indicated the upload worked based on the blinking LEDs.)
Now I want to get the native bootloader to work. I set the Mailbox ID = 1, the baud rate to 500KBps (XCLKIN = 20MHz) and jumper GPIO18 to gnd in the 280xx Boot section of the dev kit.
Boot loader options for hex file are: --romwidth=32 --diag_wrap=off --boot --sci8 --ascii
However, when I try the bootloader method, everything looks like it is working, but the led flash rate is not switching, indicating the current bootloader failed.
Anything else about the bootloader I haven't considered?
I have attached a small file to show the first few bytes that are transferred - captured by Salaea Logic tool.
