Dumper tools for non-volatile memory

[Eirik Stople]

These tools allows you to dump the full contents of:

ROM (512 kB)
SMC (8 kB)
VERA flash (2 MB)
RTC (96 bytes)

This can be done before/after a system update, during development, for backup, or for any purpose you see fit.

NB: Make a backup of the SD card before using these tools! One severe kernal bug was discovered when making these tools https://discord.com/channels/5475596260 ... 9931302008 , which corrupted the SD card. The programs are written to try to avoid the kernal bug.

This tool have been tested with these versions installed:

ROM R48 + SMC 47.2.3 + VERA 47.0.2 + SMC bootloader v3
- Latest release as of 2024-10-30
- All tools works as expected
- Note that if boot v3 failsafe is installed, 3 bytes in the beginning of SMC is different compared to the release, which is expected
- Is also tested with bootloader v2(bad), same results

ROM R47pre 8929A57+ + SMC 45.1.0 + VERA 0.3.2 + SMC bootloader v2(bad)
- These are the versions delivered with my machine PR00102
- I have attempted to recreate this setup, although I do not have a dump of the original ROM
- I have installed a ROM dump from some other user having the same git hash
- SMC tools runs and gives an output, but all bytes are FF and are not meaningful. This is expected, and is because SMC version 47.2.3 is required to dump SMC flash
