Do we currently have a way to store data in EEPROM or some other flash storage? It’d be great to have a way to have the Core resume where it left off after a disconnect by reloading the last arguments passed via REST, rather than resetting to your program’s default variable values.

@twalsh , Please see this post by Zach :slight_smile: [image] Let's get (non)volatile Firmware One option is to use the external flash; the Core has 2MB of external flash, of which we’re only using 0.5MB, and the remaining spac…

Hmm… I tried using the sFLASH_WriteBuffer and sFLASH_ReadBuffer functions the way Zach mentioned, but this just results in my Core becoming unresponsive to reprogramming and REST commands. To recover, I actually have to do a full factory reset. Need to do a little more debugging/digging into it, bu…

In order to help show what I’m doing/what my issue is, I’ve attached a link to my program below. It’s not anything particularly useful, I mainly wrote it to give me a simple way to get familiar with setting up cloud-controlled functions and a few other little features of the Core. All my example do…

@twalsh You probably need to erase the flash sector before writing to it as described lower down in that thread: [image] Let's get (non)volatile Firmware The functions like sFLASH_ReadBuffer and sFLASH_WriteBuffer for working w…

Ah, I’d missed that. Yeah, after adding that in, (and adding a 10 ms delay between each flash operation, not sure if that’s needed but it’s the only way I got my code working), things seem ok, though the Core locks up on the first REST command received after being powered up. A reset quickly gets i…
