Response Code.
0x00 = OK booting application
0xF0 = CRC/Signature failed. If
this is received, the bootloader
“believed” it had a valid application
loaded but a re-check of the
CRC/Signature failed. (This
should be quite rare and indicates
a significant glitch occurred during
the loading process, or the device
has bad flash memory.)
0xFF = Other error. Usually
returned because the application
flash area is blank, or an
incomplete application is loaded.
This will occur if the “0x61”
command is used to load some of
the file, but the “End of File”
marker was never seen.
If either 0xFF of 0xF0 are
received, the user should attempt
to load the application again.

CRC
4.4.2.4 0x63 “Status Query”
A query to determine if the bootloader is running, or the application is running. Response code will be 0x00 if the
application is running, and 0x05 if the bootloader is running.
