LMM P2 Debugger - Uses Serial Tx & Rx for debugging single cog programs

Cluso99 · 2013-04-03 22:01

Sorry. v0.43 is the last posted code. v0.44 is the one I am about to work on next.

Hi Cluso.

How I can modify Yours LMM RX routine to have "waitio" only flag without waiting to sample Character

Cluso99 · 2013-04-10 20:27

Sapieha,

                waitcnt lmm_w,lmm_bittime               ' wait until bit period elapsed /

I think this is what you will need to do...
Your user code will then need to look for the beginning of the start bit and immediately call _RX routine

_HubRx                                                  '                       <--- receive character --->
{{ returns lmm_x = -1  if no character or invalid }}
{{ presume we have already detected the commencement of the start bit }}
                getcnt  lmm_w                           ' get initial time              \ setup 0.5 bit time
                mov     lmm_x, lmm_bittime              ' bit period                    |
                shr     lmm_x, #1                       ' 0.5 bit period                |
                add     lmm_w, lmm_x                    ' add 0.5 bit period to time    |
                waitcnt lmm_w, lmm_bittime              ' center of start bit           /

                getp    #_rxpin                 wc      ' check start bit =0            \ verify start =0

Hi Cluso.

Thanks.

Will see If I can manage that changes to Yours LMM.

Hi Cluso.

Cluso.
It is possible You can add that type display of one LONG

Then I can use my break to IN Real values display that POSITION in COG to see how that long have be modified

tst2        cmp        xxx,yyy        Wz,Wc

Sure Sapieha.
How do you want to get the cog address in there?

Postedit
Would you like it to be an option for the DUMP command? (use _CODE option) We already have _COG/_HUB so we could dump hub LMM too.

Sapieha · 2013-04-13 03:05

Hi Cluso.

It can be DUMP -- One long at time.

jmp ENDS

Every time I place that (jmp ENDS) break address I recompile and reload.
And after it run I check what happens in that parts code and its variables

Addresses that I'm interested of -- I find by look in CTRL-L option in PNut

Cluso99 · 2013-04-13 10:17

Sapieha: Not quite sure if this is what you are after...

I have added the mode #_DUMP+_COG+_CODE
There are 2 calls in the sample part of the program (lmm_x is the cog address and lmm_y is the mode - they are both sticky with the address incrementing). I have not done hub mode for this yet. I have just coded it simply for now.

It is correct what I have wanted.

Have You merged Check_Serial in this version to ?

LSD_045.spin

Cluso99 · 2013-04-13 11:39

Sapieha:
Here is another update. It now works for hub too.
I have added two new commands to the Debug/monitor mode (interactive mode)...

xxx'<cr> will display the cog address (instruction) code, and
xxxxx"<cr> will display the hub address (instruction) code.
A <cr> will display the next address.
Note leading zeros may be omitted in the addresses.
LSD_046.spin

No, I have not added the check_serial. I need to think about how to have both options.

Sapieha · 2013-04-14 00:00

Hi Cluso.

THANKS.

Now it function that wanted - I can break and see what instructions are doing

Glad it works for you Sapieha.

You can also return to your code and continue too. Currently I use <esc> and that terminates p2load's terminal program, so I need to rethink another control char to return to the user cog code.

Sapieha · 2013-04-14 04:41

Hi Cluso.

I'm are one that never will be happy --

excuse that !

So I have one question?

How much work it are to made that?


  000- 000011 001 1 1111 057 00D --> 0CFCAE0D --in Ram -> 0DAEFC0C

Ps. Mode for showing Real addressees with instructions Bits --- Give me simpler work to debug my Basic.
Thanks

Cluso99 · 2013-04-14 06:20

Easy to do. Do you want both hex values or just reversed if in hub?

Sapieha · 2013-04-14 06:29

Hi Cluso.

Thanks

I wanted both ---> First HEX are for simple showing BIN in correct arrangement
---> in RAM are for seek in WinHex else like HEX file editor to find it

Cluso99 wrote: »

Sapieha · 2013-04-14 06:36

Hi Cluso.

Next question are more complicated.
one more command to COG showing

"<" GoTo Address XXXX

000<

Run this addres

Cluso99 · 2013-04-14 11:04

goto this address in cog instead of returning to the next address? easy
what about z and c flags - just ignore?

Sapieha · 2013-04-14 11:45

Hi Cluso.

No need for preserve Flags.

Only GoTo any COG address I specify on DEBUG command line --- So I don't need Edit 1 value in Code -- Recompile and load.

I simply can place ADD XXXXX,#1 and test many rounds before need for Recompile and reload
else with RXLine manage moving new value to Variable

Cluso99 · 2013-04-14 18:23

Sapieha: Seems what you really need is for me to add in the single stepper code from my old P1 debugger. But meanwhile, I will add the goto function, maybe later today.

Sapieha · 2013-04-14 19:01

Hi Cluso.

Not need for single stepper For me.
I use to that KEY's-1,2,3 on DE2-115

But to that I need ---- RUN (GoTo) --- XXX address in COG

Cluso99 · 2013-04-14 19:22

Here is v0.47

Additions:
xxx!<cr> resumes user code at cog address xxx (i.e. goto). xxx may be omitted for addr=0.
Dump code now also displays hex and hex reversed in addition to the instruction format. Works for both cog and hub.
Ctl-Z<cr> now passes control to the Rom Monitor (was <esc> but that conflicts with p2load Terminal mode)

Cluso99 · 2013-04-14 21:53

Sapieha,
No problems. Glad I can help. Any suggestions/requirements can only make the tool more useful to everyone.
I am not sure what you are asking on your last request.

Really looking forward to your Basic.

Cluso99 · 2013-04-14 22:21

Sapieha:
If you wish to post your modifications to the _RX routine, I will include them to make it easy for you to comment out or skip my _RX. This should make it easier for your to use my later versions.
