There is an unknown syscon response of 0x100 bytes when using NVS service with such params: BlockID=1, Offset=0, Size=0.
There is an unknown syscon response of 0x100 bytes when using NVS service with such params: BlockID=1, Offset=0, Size=0.
Sometimes the whole region is filled with FF's (empty, never used, or erased), it seems this procedure can be used to reset it


It can be considered an structure composed by a 0x10 header, and six available "slots" of 0x28 each, the second byte of the header seems to be some kind of counter related with the slots where the only values posibles are 0-5. The presence of data in the slots could vary usually all them are filled with data but in some rare cases the slots are empty (filled with FF's)

The structure of an slot seems to be: 0x4 (timestamp) + 0x2 (unknown, always 0000) + 0x1 (unknown, always 0xE1 or 0xE2) + 0x1 (Data Size ?, usually 0x18) + 0x4 (Data Type ?) + 0x1C (data, included padding)
The structure of an slot looks like this, last 8 bytes seems to be always zeroes (padding ?), and the previous value (0xFFFFFFFF, 0xAAAAAAAA, 0x55555555 in this samples) could be some kind of timestamp, the samples below can be considered rare. The 0xFFFFFFFF, 0xAAAAAAAA, 0x55555555 seems to be used as some kind of fallback
*The timestamp follows the same format than the timestamps of the [[Syscon_Error_Codes#Error_log_format|Syscon Error Codes]], in some syscon models the lowest value posible for this timestamps seems to be 0x0B488680 (2005/12/31 00:00:00)
