> I’m not sure how this would work. The Pico does have a flash chip where the program is loaded but no file system is configured by default. If we had a filesystem we could easily copy the chip firmware as it is supplied by pico-sdk as a binary file which we could read from anywhere. Putting this on a filesystem would not actually help though. It is easy enough to add the binary data to the NuttX image, and it would wind up stored on the same flash chip anyway. Why add file system overhead. If you don't have the real file system, you can try ROMFS which is bundled into your image directly, here is an example ROMFS usage: https://github.com/apache/incubator-nuttx/blob/master/boards/sim/sim/sim/src/Makefile#L58 > Loading the nvram image is more of a problem. It is only available from pico-sdk as an include file. That is useless at run time, and if I were to pull the data out of that include to make a file that could be loaded at run-time, I’d still need to store it somewhere in the repo, which it the issue we’re trying to avoid. nvram image is normally specific to your hardware design, so it's always good to put into your board specific folder instead of the common place. -- This is an automated message from the Apache Git Service.
