I was looking at the K65 linker file that MQX 4.2 uses and was wondering if the rom entry and cfmprotrom have the correct parameters. Should it be like this instead?
cfmprotrom (R): ORIGIN = 0x00000400, LENGTH = 0x00000010
rom (RX): ORIGIN = 0x00000410, LENGTH = 0x001FFBF0 /* Code + Const data */
The part on the board is a MK65FN2M0VMI18.
