WORKS ON R6!!!!

https://www.magiclantern.fm/forum/index.php?topic=24827.msg230456#msg230456

Might want to change the subject of this thread to DIGIC 10 too.

Canon Basic script for running a small binary. The five function addresses listed at start are required to be correct. The initial values are for sx740 1.0.1
The binary is loaded in uncached RAM and executed as-is. The firmware always applies cache and branch predictor related routines on code loaded to RAM, so there is a possibility that this approach is not fully reliable.
Code: [Select]
' firmware function addresses with thumb bit
dim a_fio_readf=0xE0520E8B ' FIO_ReadFile
dim a_fio_writef=0xE0521027 ' FIO_WriteFile
dim a_fio_removf=0xE0520DF1 ' FIO_RemoveFile (newer cams have an equivalent RemoveFile eventproc)
dim a_umalloc=0xE053A0B1 ' AllocateUncacheableMemory
dim a_ufree=0xE053A0E5 ' used to free AllocateUncacheableMemory allocations (not named)

dim cpuinf_binary="B:/CPUINFO.BIN"
dim cpuinf_data="B:/CPUINFO.DAT"

private sub reg_funcs1()
    ExportToEventProcedure("FIO_ReadFile",a_fio_readf|1)
    ExportToEventProcedure("FIO_WriteFile",a_fio_writef|1)
    ExportToEventProcedure("FIO_RemoveFile",a_fio_removf|1)
    ExportToEventProcedure("umalloc",a_umalloc|1)
    ExportToEventProcedure("ufree",a_ufree|1)
end sub

private sub Initialize()
    reg_funcs1()
    buf = umalloc(0x1000)
    if buf=0 then
        exit sub
    end if
    bufo = umalloc(0x1000)
    if bufo=0 then
        ufree(buf)
        exit sub
    end if
    memset(bufo,0,0x1000)
    f = OpenFileRD(cpuinf_binary)
    FIO_ReadFile(f,buf,0x1000)
    CloseFile(f)
    ExportToEventProcedure("cpuinfo",buf|1)
    cpuinfo(bufo)
    FIO_RemoveFile(cpuinf_data)
    f = OpenFileCREAT(cpuinf_data)
    CloseFile(f)
    f = OpenFileWR(cpuinf_data)
    FIO_WriteFile(f,bufo,0x1000)
    CloseFile(f)
    ufree(bufo)
    ufree(buf)
end sub
Assembly source for the current CPUINFO code from here. It now supports ARMv7 VMSA (such as Cortex A9) CPUs.
Code: [Select]
@ compile with:
@ arm-none-eabi-gcc -Wl,-N,-Ttext,0x800000 -nostdlib -march=armv7 -mthumb cpuinfo.s -o cpuinfo.elf
@ and extract the needed bytes from the binary:
@ arm-none-eabi-objcopy -O binary cpuinfo.elf cpuinfo.bin
@ toolchain: [url]https://launchpad.net/gcc-arm-embedded[/url]
@ 0x00800000 is an arbitrary address, code is position independent anyway

I already executed this on my camera and found no big differences from DIGIC 7.
Running this on R5 or R6 would be more interesting.

Evaluating the CPUINFO.DAT binary is currently only possible on a D6-D7 CHDK cam with patched CPUINFO module. Porting the evaluator to "PC" would solve that.

Thanks, this is quite interesting.  Are you aware of Scout debugger?

https://github.com/CheckPointSW/Scout

In theory this can be loaded into Canon cams and act as a network debugger.  I played with it briefly but couldn't work out how to build it.

It was mentioned in their ransomware article. Never tried to use it.

They mention it worked, but the subject was a DIGIC 6 camera. DIGIC 7 and later has a separate core for networking. The firmware refers to it as "Lime". That CPU is not ARM, it's Xtensa. And that architecture is not supported by Scout.

Maybe subject needs to be chanced a bit. My 250D/200D Mark II/Rebel SL3/Kiss X10 does execute Canon Basic script and produces ROM.TXT. Zero Bytes but it is written nevertheless!
Correction: 2 129 920 Bytes
Want to have a look? -> PN

Any hints what is needed to dump valid bits and bytes?

90D, M6 II, G7X III: Users around? Making a script card is easy!
If there are troubles I promise to assist via Teamviewer (or else).

Fine! Start coding and repost with an early beta. Est. 2023.

I found stubs for R6, got cpuinfo dumper built.  Thanks to @yourboylloyd who is a brave tester, we can confirm it works.  I'm now porting the code to linux so I can view the results.

I found stubs for RP and dumped cpuinfo on my cam. I will publish the results once the parser of names_are_hard is ported.

RP stubs for firmware 1.5.0 are:

Code: [Select]
dim a_fio_readf=0xE0584C07 ' FIO_ReadFile
dim a_fio_writef=0xE0584D9F ' FIO_WriteFile
dim a_fio_removf=0xE0584B6F ' FIO_RemoveFile (newer cams have an equivalent RemoveFile eventproc)
dim a_umalloc=0xE0594A8D ' AllocateUncacheableMemory
dim a_ufree=0xE0594AC1 ' used to free AllocateUncacheableMemory allocations (not named)

I have a crude early port of the cpuinfo parser.  There's some conditional stuff around VMSA, PMSA and v5 / v7 that for now I ignore.  I don't have a good way to check if the output is sensible.  Here's a truncated example:

Code: [Select]
./build/parser cpuinfo.rp.dat && cat CPUINFO.TXT

ID         0x414FC091
  Revision             0x1 1
  Part                 0xC09 3081
  ARM Arch             0xF 15
  Variant              0x4 4
  Implementor          0x41 65
Cache type 0x83338003
  Icache min words/line 0x3 3 [8]
  (zero)               0x0 0
  L1 Icache policy     0x2 2
  Dcache min words/line 0x3 3 [8]
  Exclusives Reservation Granule 0x3 3 [8]
  Cache Writeback Granule 0x3 3 [8]
  (zero)               0x0 0
  (register format)    0x4 4
TCM type   0x00000000
  (raw value)          0x0 0
TLB type   0x00000404
  TLB                  0x0 0 [Unified TLB]
  TLB entries          0x2 2 [256]
  -                    0x0 0
  Lockable unified or data entries 0x4 4
  Lockable instruction entries 0x0 0
  (zero)               0x0 0

Does that look obviously wrong to anybody?

@srsa - can I ignore memmapping_vmsa(), or is it important to get that working?

The output is correct. The parsed text can be added to this thread.

That is only usable on camera, and only makes sense if one is trying to make changes to the memory translation.

I ended up hacking standalone support into the cpuinfo source (cpuinfo.c and cpuinfo_v7.c from here). Patch below. The patched 2 files can be compiled with
Code: [Select]
gcc -m32 -o cpuinfo.exe -DCPUINFO_STANDALONE cpuinfo.c32-bit only due to arch-dependent types in source.

Great!  Added R6 and RP to thread.

I stole your bit twiddling fix and made a repo with my standalone tool.  Tested on Linux, should be portable with minimal changes if anyone needs it.
https://github.com/reticulatedpines/cpuinfo_linux

Yours and mine produce identical output for R6 and RP.

So people are already working on the R6 with ML and skipping the M50 altogether?

A lot of work has been done on the M50, but there are no active developers working on the camera. If you have coding experience please help on the m50's development.

I'd personally like to help, but I don't know where to start, as I don't know all that much about the way the firmware works. Could I ask if there are any relatively low-hanging fruit regarding the M50 that I could try and pick at?

First question: Are you willing to put several hundred hours of work into it?

I'm certainly more than willing to try. I'm aware of the amount of work necessary for this sort of thing, and unfortunately right now I don't really have much else to put hundreds of hours of work into…

I'm not about to give a resume here, both because I don't want to dox myself and because I don't feel like trying to convince anyone that I've got experience hacking hardware. But I can assure you I do, and I've been needing an excuse to learn ARM/thumb assembly anyway.

srsa posted some specific code here that can be used to get some interesting information out of the camera.
https://chdk.setepontos.com/index.php?topic=13943.msg144153#msg144153

Code: [Select]
private sub Initialize()
    System.Create()
    CamInfo_Debug(1)
end sub

The Canon Basic Code creates a CameraInfo.xml file.
The file contains information such as TotalShoot, TotalRunningTime, ErrorList ...
I would be interested in a CameraInfo.xml from an R5 and R6, especially one that has already crashed.

A CameraInfo.xml of my M100 is here (renamed to txt).

Thanks, looks like your camera was crashed before…
I’m wondering about the BatTemperature = 0.
Do you use external power supply?

And on R5 is a TotalShoot and TotalShutter count...

It's probably because there is a mechanical shutter and electronic shutter.

But it is also on R5

M50 has also an TotalSW2 count...

Shutter count seems to be invalid.
