Flash and ISP specification
BatchISP programs faster than JTAGICE mkII. Under IAR, this will require to suppress JTAGICE
mkII download in the project options:
In this case, if IAR project options request JTAGICE mkII download verification, an expected
warning will be issued by IAR because it will see the bootloader in the part at the location of the
trampoline in the binary image.
To add the trampoline to a GCC project, do the following in
