What happens when NVRAM fails ? i mean after some thousands read writes It fails a single block and you lose the settings or as a whole ? Does it have corruption handling capabilities ? In DD-WRT v23 i use even for the slight change you have to press 'Save' (aka save the whole NVRAM most of the times - also reboot in most cases) Shouldn't it be better to have the web interface written so that you make all changes in all pages and commit them once ? (even in that case my question remains - but that way the corruption would take years more to come) P.S. Because i dont know my way around routing and stuff I go the easy way (I try all possible compinations instead of reading the f. manual It's a gambling approach that rarely works but its is bad for the flash... I know because i have made useless a flash chip in another scenario (Atmel AVR microcontroller after continuous flashing) but it was a 3$ piece not a 25x times worth of equipment thats why I'm asking you) The instalation of a SC card slot minimizes writes to the internal NVRAM or not ? Thanks
