If that's the case, then we still need some explanation on why it affects data retention of only a specific partition. Anyway, we need more evidence. A gas torch is the worst tool I can imagine of to heat-up a PCB. It is absolutely possible, that the cold contact is somewhere near the chip...

I think, I now understand, why Netgear and other manufactures continue using NVRAM partitions for keeping the essential settings. The answer is simple: to survive firmware upgrades, otherwise if all the settings are kept as uci configs, users will have to reconfigure or restore settings from...

Yes, and what is it used for?

Does anybody know, what's the purpose of NOR flash (mtd13)? Maybe to keep the NAND erase counters?

OpenWrt article describes UCI in detail. And R7800 stock firmware is definitely using it to some extent: uci show lists all the configs, found in /etc/config/* The advantage of UCI is that you don't need a small dedicated partition for settings, as is the case with NVRAM, as a result, using a...

Hi @kamoj, thanks for welcoming! Somehow missed the first post :) I was confident, the kernel ring buffer size is not enough to keep the early lines! I was wrong) So, just collected the logs, and it appears to be MX30UF1G18AC - Macronix. The second post, yes, I read it. Hope, I can also get some...
