PIC24F16KA102 [solved] - dwight - 2010-08-13

Hello
I found bug in bootloader. In PIC24F16KA102 uC U1RX and U2Rx pins are default use as analog input so UART don't work correctly.
Fix:

in ds30loader.s file:

Code:
;------------------------------------------------------------------------------

; Init 

;------------------------------------------------------------------------------

        ; Uart

        .ifdef USE_BRGH    

            bset    UMODE, #BRGH

        .endif    

    mov     #0xffff,W0

        mov     W0,AD1PCFG

        mov        #UARTBR, W0         ;set    

        mov     W0, UBRG            ; baudrate

i added lines:

Code:
    mov     #0xffff,W0

        mov     W0,AD1PCFG

now bootloader works

Regards and thanks for great work

Thank you dwight for the report! I'll see if I can incorporate this in the next release.

Hi,

I'm trying to run ds30 loader on PIC24F16KA102

but I have get Error Message in GUI.
How can I fix it?

      Found PIC24F16KA102 fw ver. 0.9.4

      Unknown firmware version

Dwight, is the bootloader working ok for you?
Could you please tell me what revision of the device you are using.
