megaAVR JTAG programming doesn't work for SNAP and PICkit4 #1052

Closed MCUdude closed 1 year ago

MCUdude commented 2 years ago

I added the following programmer to avrdude.conf to see if I could get JTAG programming to work. JTAG works just with both the PK4 and the SNAP in MPLAB X. I've enabled both the OCDEN and the JTAGEN fuse for good measure.

programmer
  id    = "pickit4";
  desc  = "MPLAB(R) PICkit 4 in JTAG mode";
  type  = "jtagice3";
  connection_type = usb;
  usbpid = 0x2177, 0x2178, 0x2179;
;

programmer
  id    = "snap";
  desc  = "MPLAB(R) SNAP in JTAG mode";
  type  = "jtagice3";
  connection_type = usb;
  usbpid = 0x217F, 0x2180, 0x2181;
  hvupdi_support = 1;
;

PICkit4

$ ./avrdude -cpickit4 -p atmega1284p -B8

         Vtarget                      : 5.07 V
         JTAG clock megaAVR/program   : 125 kHz
         JTAG clock megaAVR/debug     : 100 kHz
         PDI/UPDI clock Xmega/megaAVR : 100 kHz

avrdude: JTAGEN fuse disabled?
avrdude: initialization failed, rc=-1
         Double check connections and try again, or use -F to override
         this check.

avrdude done.  Thank you.

SNAP:

$ ./avrdude -csnap -p atmega1284p -B8
avrdude: usbhid_open(): No device found

         Vtarget                      : 5.06 V
         JTAG clock megaAVR/program   : 125 kHz
         JTAG clock megaAVR/debug     : 100 kHz
         PDI/UPDI clock Xmega/megaAVR : 100 kHz

avrdude: JTAGEN fuse disabled?
avrdude: initialization failed, rc=-1
         Double check connections and try again, or use -F to override
         this check.

(Note that the debugWire support for these programmers is also lacking, but I haven't checked to see if dW works with these or not)

bonidydy commented 2 years ago

Programming with SNAP over JTAG works with gdb and "Bloom" debug server https://github.com/bloombloombloom/Bloom.

MCUdude commented 1 year ago

I've tested a little more and can confirm that the SNAP and PICkit4 work with Xmega targets using JTAG. However, I'm still having issues communicating with "standard" 8-bit AVRs over JTAG. Really weird... Especially since other JTAG3/EDBG compatible programmers have no issues with JTAG.

$ ./avrdude -patxmega256a3bu -csnap -B10

@bonidydy

Are you using the SNAP / PICKit 4 with class AVR in JTAG mode or with ATxmega parts? What is the issue you encounterd?

mcuee commented 1 year ago

I can reproduce the issue. Connection as per Page65 from PICKit 4 user guide. target is ATmega32A. OCDEN and JTAGEN are programmed (as 0). http://ww1.microchip.com/downloads/en/DeviceDoc/PICkit4%20In-Circuit%20DebuggerUG-DS50002751B.pdf

And I made sure that it works with Atmel Studio 7.0 first (JTAG programming works)

PS C:\work\avr\avrdude_test\avrdude_bin> .\avrdude -c pickit4 -p m32a -B8

         Vtarget                      : 4.93 V

avrdude error: JTAGEN fuse disabled?
avrdude error: initialization failed, rc=-1
        - double check the connections and try again
        - use -B to set lower ISP clock frequency, e.g. -B 200kHz
        - use -F to override this check

Need to learn how to use debugWire. It does not seem to work. But I need to check if it works with Microchip Studio or not first. Once I enable DW bit, I can not communicate with the ATmega328P with AVRISP mkii (reset pin is now DW pin), which is expected.

Edit: TO DO -- to check whether PICKit 4 supports DW or not under avrdude. By right it should work. Connection: https://microchipdeveloper.com/pickit4:interface-pinouts

#------------------------------------------------------------
# pickit4 in DW mode

programmer
  id    = "pickit4_dw";
  desc  = "MPLAB(R) PICkit 4 in debugWire mode";
  type  = "jtagice3_dw";
  prog_modes = PM_debugWIRE;
  connection_type = usb;
  usbpid = 0x2177, 0x2178, 0x2179;
;

PS C:\work\avr\avrdude_test\avrdude_bin> .\avrdude -c pickit4_dw -p m328p

Unfortunately I do not have JTAGICE mkii which supports the function to program the ATmega328P even with DW bits enabled. I have the AVR Dragon which is supposed to be able to disable DW and enable ISP again using Atmel Studio as per Page 19 of the user guide. https://ww1.microchip.com/downloads/en/devicedoc/atmel-42723-avr-dragon_userguide.pdf

Under MPLAB X 6.0 here is the output for PICKit 4.

@MCUdude

I check under Microchip Studio, PICKit 4 will not support DW mode of ATmega328P, only ISP mode is supported.

Edit to add: Microchip Studio has never supported DW for programming, only for debugging.

As for ATmega32A, Microchip Studio supports ISP and JTAG using PICKit 4.

bonidydy commented 1 year ago

Again I would like to point out the project "Bloom" https://github.com/bloombloombloom/Bloom which is a debug server for gdb. It can not only debug with PICKit4 and SNAP over DebugWire but also program targets with the gdb's "load" command. The same applies to JTAG, PDI and UPDI.

mcuee commented 1 year ago

I will check out Bloom, as of now it seems to only support Linux, so it is probably not a solution for many avrdude users on Windows and macOS.

MCUdude commented 1 year ago

@xedbg you're probably busy right before Christmas, but do you know if something as trivial as a flag or state needs to be set on these gen 4 programmers in order to support megaAVR JTAG programming?

MCUdude commented 1 year ago

For reference, here are two verbose output logs. One for Atmel ICE (that works), and one for PICkit4 that fails. The PICkit4 fails at the sign-on command, and responds with a 0x33 error, even though the Atmel ICE and PICkit4 run the exact same initialization routine.

My setup is also working, because I can ping the device over JTAG using pymcuprog:

@MCUdude Christmas is a time for debugging, right? :)

Looks to me like there is some config missing before activating physical: reason 0x33 there are a few "must haves" for debugging (which unfortunately means programming too :/ )

For programming, the first two are needed - the rest can really be dummies

It looks like the flash page size and flash size are already present. and I can confirm that it works with Atmel ICE and the Power Debugger, so my initial thought was that GEN4 programmers need a slightly different initialization.

Pymcuprog/pyedbglib is a nice rabbit hole to go down, but I'm not able to get a proper verbose debug output, so I have no clue which initialization packets are sent. If there where I could compare them to the ones Avrdude sends to see if I could figure out what Avrdude is doing wrong.

@MCUdude give us a minute then... Christmas lunch is only at 12... ;) Edit: 12:10 to be precise
