I followed the UM11071 on page 36 to Reinvoke ISP in USB Mode(4.6.8)but it does not work.
Do I need to add others code to make it work.
I used the lpcxpresso51u68_dev_hid_generic_freertos example and the LPCXpresso board for LPC51U68
I am able to pass the Cmd 57 and param0 = 2 from my application
the changes are in
USB_DeviceHidGenericCallback function in hid_generic.c
