v2n-eeprom-manifest-dump

Raw hex-dump of the 128-byte EEPROM manifest, with a per-field decode after. Useful for verifying factory-test programming and debugging CRC failures.

Source: examples/v2n/v2n-eeprom-manifest-dump/.

What it does

1. Opens BRD_I2C and instantiates eeprom_24c128_t at 0x50.
2. Reads bytes 0..127 from the EEPROM into a 128-byte buffer.
3. Hexdumps the buffer (16 bytes per row, ASCII gutter).
4. Decodes the structured fields: magic, schema version, family, SKU, hw_rev, serial, mfg date, CRC32.
