I have a small configuration file to store in onboard flash. The configuration file is writen on each setting change. As some settings are exposed in an API then I need wear leveling. The NVS system does not seem to support wear levelling. I tried FATFS. The manual says: The wear levelling component...

Are you Ardunio or ESP-IDF? Websockets are a good idea but not supported in the stock ESP-IDF server. If IDF then you would need to port an Ardunio library. I tried briefly and decided (deliverable was due) that Ajax would do. I would say WebClient and use the Ajax (Google w3fools/schools) approach....

Its better to post a link if you are using stock code, saves me checking if you have changed anything. Is this stock code? You also should post observations not conclusions. For example, you say that the LAN is initialised but how do you know? Sending your boot output messages would help. Even bette...

The EVB schematics are a good starting point. I don't see an invertor there. You need to post some code and/or provide a common reference point e.g. the worked example. but lan ic is enabled. What do you mean? How do you know? What's your ethernet_initialisation() code & configuration settings? Ever...

Thanks. Spiffs does not use mmapped reads. Fatfs only uses them on encrypted partitions and only mmaps them ]just in time, not the whole filesystem. Not sure I understand the distinction and/or use and implications of using mmapped reads. Clearly mapping just in time will give a performance hit. Wha...

Thanks and darn, 3.1MB - that's bad. That has me on the hairy arse end of disaster.... Do you have a reference? What is the 16MB use/case then? You have 16MB but cannot use it? I don't understand the rules. Also how are SPIFFS/FAT etc located and addressed? SPIFFS can do >4MB. I started out with my ...

I very much doubt that you would achieve 5Mhz on UART regardless of direct/mux. I struggle to achieve UART speeds above 500K. I happily achieve 100Mhz+ with Ethernet. 20 MHz+ on 30cm on dodgy dupont wire with SPI (not suggesting the latter as a production option, just to say that something is wrong ...

SPIFFS allows read and write. Your first example works because you create the file "hello" using the 'w' option. This will create the file if not present. In your second example you attempt to open "foo.txt" as read only. This will not create a file if missing and so you get file error if missing. Y...

Well calling 'make app' from a script would be easy enough! (and then on completion rename). Where do you propose to get the version information from? ESP seem to work on the principle that we are using release branches and so the branch name contains the version plus minor as hash. In this case 'gi...
