STM32F76x devices have wrong memories

[mikewolfram]

Found a place, in tools/generator/dfg/stm32/stm.py:

    'f7': {
        'start': {
            'flash': 0x08000000,
            'dtcm': 0x20000000,
            'itcm': 0x00000000,
            'sram': 0x20010000,
            'backup': 0x40024000
        },
        'model': [
            {
                'name': ['22', '32', '23', '30', '33', '45', '46', '50', '56', '65', '67', '68', '69', '77', '78', '79'],
                'memories': {'flash': 0, 'itcm': 16*1024, 'dtcm': 64*1024, 'sram1': 0, 'sram2': 16*1024, 'backup': 4*1024}
            }
        ]
    },

Is that the right location?

According to STMCUFinder the F76x and F77x have 128kB, all other F7 only 64kB DTCM.

[salkinium]

Yes, that's the right location. I'm sorry for the bugs, but this info isn't part of CubeMX, so I had to add it manually. This is the reason I really don't like it.

[mikewolfram]

No worries, nobody's perfect.

Changing the size of the DTCM would that automatically adjust the start address of SRAM?

[salkinium]

No I don't think so. The algorithm is at the bottom of that file, it may require an extension to allow for custom start addresses per table entry.

[salkinium]

Ugh, it's a mess:

[mikewolfram]

The pic is a bit misleading. The data from STMCUFinder looks more clear to know which F7 has which RAMs.
