I want to use the ds30 Loader with my dsPIC30F411.
What kind of changes did I have to do if my external Oscillator is about 20 MHz (its a stupid choice cause I couldn't use the PLL) and I take the alternate UART1 Pins?
Only this one on settings.inc:
Code:
;------------------------------------------------------------------------------
; Device
;------------------------------------------------------------------------------
;.equ __24F16KA102, 1 ;xxx uncomment and change if using PIC24F device
;.equ __24FJ128GA010, 1 ;xxx uncomment and change if using PIC24FJ device
;.equ __24HJ128GP504, 1 ;xxx uncomment and change if using PIC24HJ device
.equ __30F4011, 1 ;xxx uncomment and change if using dsPIC30F device
;.equ __33FJ256GP710, 1 ;xxx uncomment and change if using dsPIC33FJ device

.endifAnd how must look my application (Hexfile)?
