*In the sample below:
**The oldest errorcode is located at offset 112
**The newest errorcode is located at offset 104
**The errorcode FFFFFFFF at offset 108 is a mark indicating the errorlog has been looped (is not an error, and the associated timestamp is not valid, the timestamp 2013/02/23 05:54:19 is garbage)
**The next errorcode will be stored at offset 108, and the loop mark will be moved to 112 overwriting the oldest errorcode but not overwriting the oldest timestamp (so it will inherit the timestamp 2013/06/09 06:43:04 as garbage)
**When the errorcodes from offsets 112, 116, 120, 124, 0, 4, 8, 12 was triggered (orderd from old to new) the battery was present and the date and time was correctly configured under GameOS
**When the errorcodes from offsets 16, 20, 24, 28, 32, 36, 40, 44, 48 was triggered (orderd from old to new) the battery was not present
**When the errorcodes from offsets 52, 56, 60, 64, 68, 72, 76, 80, 84, 88, 92, 96, 100 was triggered (orderd from old to new) the battery was present, but the date and time was not correctly configured under GameOS
**When the errorcode from offset 104 was triggered the battery was not present
**This errorlog was close to complete his second loop (the second loop is completed after the loop mark overwrites a valid errorcode at offset 124), it had at least 59 errorcodes and is missing 5 more to complete 2 loops

*In the sample below:
**After using the command '''clearerrlog''' the errolog is emptyed (completly filled with FF), and the newest error is stored at relative offset 0 (at most top of the errorlog structure, but displayed at bottom by the comand errlog)
**There is no loop mark because there is only 1 errorcode, but syscon considers the first errorcode found with value FFFFFFFF while reading the errorlog structure from top to bottom is the loop mark (so the next errorcode at offset 8 is considered the oldest)
**The next errorcode will be stored at offset 8, and the loop mark will be considered the errorcode FFFFFFFF at offset 12
**When the errorcode from offset 0 was triggered the battery was present, but the date and time was not correctly configured under GameOS (so the date and time is automatically configured around 2005/12/31 00:00:00)

== Error transmission ==
I think it would be supercool to add descriptions of how the error is passed to syscon using a predefined visual style (common for all error codes)<br>The first detail that worths to be considered to do this is how many different ways exists to pass an error code to syscon, as far i understand there are only 2, either with a control signal not following any protocol (a simnple "pullup" or "pulldown") or by using some kind of data bus (but some of this data buses are still unknown, at least for me), anyway, we can do something like this:<br>
*Error '''1002'''
**Type = pulldown
**Adquired by:
***Mullion syscons [[Template:Syscon pinout BGA 200 pads|BGA 200]] pad D7 (RSX_POW_FAIL)
***Sherwood syscons [[Template:Syscon pinout LQFP 128 pins|LQFP 128]] pad <abbr title="Unknown">UNK</abbr>
***Sherwood syscons [[Template:Syscon pinout LQFP 100 pins|LQFP 100]] pad <abbr title="Unknown">UNK</abbr>

One of the goals of this idea is... if we know how every error code is generated then we will be able to take an scrap motherboard (for experiments) and "sabotage" it to generate some/all the error codes manually, this way we can identify them accuratelly and have a way bigger understanding of what means each and/or what sony engineers was trying to achieve--[[User:Sandungas|Sandungas]] ([[User talk:Sandungas|talk]]) 02:23, 14 October 2022 (UTC)
