Hi expert,
If I configured GPIO32 to high and GPIO24 to low, F280049 will boot through SCI.
But if I didn't send any data frame on SCI port, what will go next?
Will program jump to flash for "Not a valid keyvalue"?
Thanks
Sheldon

Hello
If you go to SCI boot and send nothing, SCI will wait indefinitely. This is why SCI doubles as wait boot as you can see in the TRM in the "Device Boot Modes" section.
If you send an invalid key, then it boots to flash.
