I use NO delay loops in the software anywhere. Everything is interrupt driven. The same code is also on the usart port in case the user wants to use serial instead of usb, and it does not lock up.

I was told by Microchip to use a 1uf low ESR cap. I am using a 1uf but not sure about the ESR rating.

I have noticed, now, that I am getting a FALSE from usb_cdc_puts(*str)
when it locks up. Incoming packets are still coming through, but it
will not let me send packets out.

It is acting like the ...

Hello,

Using PIC18F45K50 and library routines. USB works well for up to 15 minutes or so, then it seems that the PC no longer gets the
usb_cdc_puts(*str) data. We put a debug feature on the lcd ...

Hello,

Compiled and programmed ccs ex_bootloader (serial) in my 45K50.

Hello,

XC8 has an option to make the hex output file "loadable" by organizing

I see the PICC does not do this on the first couple lines. Is ther ...

Well taken, the point about the watchdog...but, I assume that when the watchdog fires, it resets the cpu. I would have seen repeated sign-on messages on the LCD.

Also, the code is over 4000 lines, ...

Hello,

Are you guys using the cdc routines that are in low memory for the boot loader ALSO for your application up high?

The only difference I see in the boot loader has a different ID string.. ...

I searched the data sheet and 96Mhz is not in the document. 48Mhz is the
highest speed listed or mentioned in the data sheet.

This chip 45k50 and the 25K50, which I am also using, have a 16Mhz internal osc. x3 yields 48Mhz (the clock necessary for USB full speed) and DIV2 yields
24Mhz which gives me a 6Mhz instruction cycl ...
