18F4550 programming failed using PICkit4 while verifying "User ID memory"

[Demon]

Any idea what it's crying about?



I had to slow the programming speed to SLOW or else I'd get speeding errors.

Program, configuration and EEdata memory seem to verify just fine. It looks like it failed at "User ID memory" - whatever that is.

This was programmed 15 years ago; no idea what's on that memory location.

Out of curiosity, did you try the PIC to see if it actually programmed? Usually the "User ID Failed" shows up before it even tries to program. Just asking.

[Demon]

So I tried with a brand new 18F4550, same error:

Out of curiosity, did you try the PIC to see if it actually programmed? Usually the "User ID Failed" shows up before it even tries to program. Just asking.

It says "programming/verify" complete though?

Gotta go feed the dogs. Gonna try with just a blinky program (this is an old program that worked way back when).

Robert

[tumbleweed]

I don't think it's complaining about the UserID area, it's just a poorly arranged display making it look that way.
The UserID is located at 0x200000-0x200007 in that part.

It looks to me that it's complaining about location 0xcc0, which is in program memory.
Try doing an erase and then a blank check.

There's a later toolpack for the 18F devices... maybe try updating it?

[Demon]

Got a new pack, same problem.




It already says ERASIN SUCCESSFUL midway down the pic.

Not sure what to try next. I don't get why I can program a 16F877 without problems.

Gonna gut my program and try to BLINKY, see if that makes a difference.

Robert

[Demon]

Gutted all the USB and interrupt stuff, added just a basic blinky, and it worked.

[Demon]

This is the complete program that failed.

Same OSC speed, same CONFIGs, gutted everything except ALLDIGITAL and ADCON1.

I've narrowed it down to USB logic. I probably have something out of date.

The LCD and blinky on lower bits of Port D work fine.

Is there an option on PickIt 4 to erase the chip before write?

When I had such messages the above solved the problem.

Ioannis

[tumbleweed]

If you look at the messages, when it fails the program end addr is 0xcbf.
It's then not seeing the next addr 0xcc0 as erased... there's still something there.

I think there's a setting to specify the full range and not let the PK4 pick it.

[Demon]

Since I had never paid attention to a command line when I was using my old serial and later USB programmers, I had no clue what I should "verify", so, I verified everything.



Turns out it doesn't like when I verify ID Memory and Configuration Memory.

This is my new command line for the PICkit 4:

-TPPK4 -P$target-device$ -F$hex-filename$ -E -M -OAS0 -OB -OL -OV -YP -YE

Note that I "might" be verifying the Programming and EEData areas a 2nd time for nothing. But hey, I paid for it so I'm using it.

I had the -E option, so no idea why it didn't want to erase the entire darned thing. It's off by default.

Programming speed, turns out it doesn't mind running at max speed for this particular PIC:

-TPPK4 -P$target-device$ -F$hex-filename$ -E -M -OAS2 -OB -OL -OV -YP -YE

This runs just fine.

I still have one bug; 18F4550 programmed by my PK4 run Blinky at 1/2 speed compared to my U2 USB programmer.

- leads on my PK4 are just over 6 inches, with gold pins so they connect directly beside the pin.
- flat cable on my U2 is nearly 3 inches long, and PGC/PGD wires on the breadboard are nearly 3 inches.

I can't find any spec that says EXACTLY what the max length is for the PK4 leads....?

Robert


EDIT: The only reference to lead lengths for the PK4 has a 8pin 6in cable:
https://www.microchip.com/en-us/deve...-tool/AC102015

[tumbleweed]

FWIW, I use a 6" cable with the PK4 all the time. Cables can cause issues, but I don't think that's your problem here.

I still have one bug; 18F4550 programmed by my PK4 run Blinky at 1/2 speed compared to my U2 USB programmer.

Try programming it with the PK4 and then verifying it with the U2, or vice-versa.

Pay particular attention to CONFIG1L. Unless one of them is changing it (????), I don't see how that is.
Are you overriding the CONFIG settings in the hex file with one of them?

Yeah, I was about to make a new cable, but that cable from Microchip is as long as mine, and they have one even longer.


Good idea about the swapping verify, gonna try tomorrow if wifey lets me in the house. I'm gonna lose a dog in that grass.


I'm not changing anything. The only variable I can think of is the options on the command lines. I'm gonna take screen shots of all the U2 settings, then compare that against the PK4.


Going to bed, just finished an "exposé" on HIDmaker FS2 (just comments and observations really), but I tried to be as open an truthful. gonna post about it on a USB thread.

Robert

[mpgmike]

The U2 Programmer has a header button that allows you to set your CONFIG settings. Since your PICkit4 and U2 Programmers yield different Clock speeds, the U2 may be using a different default CONFIG setting than the PICkit4. If you don't specifically define your CONFIGs, you are leaving it up to software to make decisions for you.

[Demon]

This is what my U2 does.

Erase:


Program:


Verify:



These are the settings I have for the PK4:

-TPPK4 -P$target-device$ -F$hex-filename$ -E -M -OAS2 -OB -OL -OV -W -YP -YE

E = Erase Flash Device (there are no options)
M = Program entire device (does not include calibration, same like U2)
OAS2 = Maximum programming speed
OB = Batch mode operation (so the window stays open to check out the results)
OL = Release from RESET NOT SURE ABOUT THIS GUY!
OV = Verify device ID before program in batch mode
W = Power target from tool
YE = Verify EEPROM
YP = Verify Program memory (U2 verifies Code, Calibration, Data, User ID and Configuration)

If anything, the U2 should be waaaaay slower, it verifies more, and the PK4 is supposed to be running at max speed and it's plugged in a SS USB port.

Weird...

Robert

[mpgmike]

You are not selecting "Erase User ID" but have selected "Program User ID". The Programming process only clears bits. If you have bits in your programmed User ID that are set, but that bit is already cleared, programming a 1 will not over-write a 0.
