PIC24FJ64GA104 Issue

[cinpezzo]

Try setting fcy to 4000000. From the datasheet:

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 . . . .
     Found PIC24FJ64GA104 fw ver. 4.0.3
     Boot loader placement/size: 2/1

Loading the fw it shows the following print:

I'm using the following fuses on the pic:

config __CONFIG4, DSWDTPS_DSWDTPSF & DSWDTOSC_LPRC & DSBOREN_ON & RTCOSC_LPRC & DSWDTEN_ON
config __CONFIG3, WPDIS_WPDIS & WPFP_WPFP41 & WUTSEL_LEG & WPEND_WPENDMEM & WPCFG_WPCFGDIS & SOSCSEL_IO
config __CONFIG2, IESO_OFF & IOL1WAY_OFF & FNOSC_PRIPLL & I2C1SEL_PRI & POSCMOD_XT & OSCIOFNC_ON & FCKSM_CSDCMD
config __CONFIG1, WDTPS_PS32768 & ICS_PGx3 & FWPSA_PR128 & WINDIS_OFF & GWRP_OFF & GCP_OFF & FWDTEN_OFF & JTAGEN_ON


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!!
