Hi all,
I'm using ds30 with different PIC 18F and it works very good!!
Now I'm trying to use it with PIC24FJ64GA104 but I'm not able to communicate...it seems there is no response from pic so GUI goes in timeout.
I'm using UART1 configured as:

RB14 (RP14) -> U1_TX
RB15 (RP15) -> U1_RX

External 8MHz crystal connected to pin 30-31.

I already configured UART1 mapping anche disabled the ADC converter in user_code.inc

;make UART1 pin Digital
bset AD1PCFG, #PCFG9
bset AD1PCFG, #PCFG10

; map pin (15 = 1111) to uart1rx
bset RPINR18, #U1RXR0 ;xxx
bset RPINR18, #U1RXR1 ;xxx
bset RPINR18, #U1RXR2 ;xxx
bset RPINR18, #U1RXR3 ;xxx
bclr RPINR18, #U1RXR4 ;xxx

; map uart1tx (3) to pin 14
bset RPOR7, #RP14R0 ;xxx
bset RPOR7, #RP14R1 ;xxx
bclr RPOR7, #RP14R2 ;xxx
bclr RPOR7, #RP14R3 ;xxx
bclr RPOR7, #RP14R4 ;xxx


I already changed the following line in setting.inc file:

; Device
.equ __24FJ64GA104, 1

; User preferences
.equiv FCY, 8000000

; UART settings
.equiv USE_UART1, 1


....I really don't understand why it doesn't work!!

In attached you can find the bootloader Mplab 8 project.
Thanks in advance to everybody!!

Regards,
Nicola

Hi,
What is the default speed of the FRC?

FRC default speed should be 8 MHz bitbut I'm not using it... I'm using an external HS 8MHz osc.

Try setting fcy to 4000000. From the datasheet:
Quote:The processor clock source is divided by two to produce the internal instruction cycle clock, FCY.

Now it communicate perfectly!! Thanks!!

Now I have an other problem related to "bl protection tripped"
Using the GUI in debug mode it shows the following print:

Searching for bl . . . .

What could be the cause of this issue???

Thanks!!!

I understood the problem...I was trying with an hex file uploaded from pic via PicKit3 so its size match the size of the pic memory and it overwrites the bootloader memory area; so this caused the "bl protection tripped" error. Using a compiled hex file with smaller size the bootloader works perfectly.
Thanks for your great support!!
