PCM Hammer P12 development

[antus]

yes the earlier attempts you mentioned where the watchdog is happy and the pcm stops responding because its in a infinite loop.

[Gampy]

I have never said the Watchdog was happy, never!

I just said the logs look the same.

I have had 3 tests return to the os, the os then sent the ack ...

[antus]

ok then I dont think your seeing the difference in the log im talking about. I'll annotate.

normal start of process:

Kernel with watchdog loop goes up and executes correctly, confirmed by there being no further RX from the pcm ~2 minutes later by the end of the log. Its alive but it can not speak

in the bin direct read from the flash chip I think this is talking to the DLC.

FFFF6CC0 is equivalent to FF6CC0 and in the other PCMs the DLC is in the vicinity of FF6xxx

We also have a loop and were comparing a register to $40 near the end which is consistent with looking for a completion code at the end of the packet. I also see a reference to 3F which sounds like a VPW error code.

I found this by looking for bytes 00 40 then looking closer to find one thats used in a compare opcode, then looked at the function around it.

Just like my first micro-kernel test ...

yep that looks like it executed and the watchdog is happy

[Gampy]

That would be impressive, considering it was all stock P01/P59,

Code: Select all

    #define DLC_CONFIGURATION          (*(unsigned char *)0x00FFF600)
    #define DLC_INTERRUPTCONFIGURATION (*(unsigned char *)0x00FFF606)
    #define DLC_TRANSMIT_COMMAND       (*(unsigned char *)0x00FFF60C)
    #define DLC_TRANSMIT_FIFO          (*(unsigned char *)0x00FFF60D)
    #define DLC_STATUS                 (*(unsigned char *)0x00FFF60E)
    #define DLC_RECEIVE_FIFO           (*(unsigned char *)0x00FFF60F)
    #define WATCHDOG1                  (*(unsigned char *)0x00FFFA27)
    #define WATCHDOG2                  (*(unsigned char *)0x00FFD006)

The success I've had is simple, and this is one of them,

It executed my code, returned to the os, the os sent the ack.

[Gampy]

O-yea, I also asked darkman5001 if he had to reboot his PCM after your bin, he says no!

If I'm not mistaken your code is an indefinite loop ... That would require a reboot to get the PCM responsive again, correct ??
That is if your code was running and the dog was happy ...

[antus]

I dont know what to make of it. Im still looking for DLC registers.

The detail about not needing to reboot paints a different picture, as does having what is clearly the wrong watchdog in your test. But I dont know why it would go silent without a working watchdog loop.

[Gampy]

I'm looking at the current direction as if it were a C void routine ...

The os receives the upload, executes the upload, the upload does it's thing then exits returning control to the os, the os then sends the ack.

I think kur4o said something like, it's a different beast, took me long enough to realize what he was saying, that's when I said I'm going in a different direction ... The direction of an empty C routine, I got the ack.
