Just wondering, is there any movement on making on-chip flash memory writable on the N+2?  

 

Yes, I know there is an SD card slot.  

 

Thanks, love this stuff.

i dont think thats a good idea. flash is also the place where the netmf and your programm is.

if they make this aviable, lot of ppl will mess this up.

also, since it has limited write cycles, its a problem.

iam sure _some_ ppl will just write some stupid variable 1000 times a second till the flash block is dead :D

 

//edit: iam not pessimistic, but realistic :D

I do this all the time with embedded devices.  It's invaluable for storage of calibration numbers, etc.

As NooM was saying its fine to do this if you know what you are doing but if you don't it could lead to severe problems for novices/non embedded engineers and as a large number of community members are hobbyists you would have to cater for the largest usecase/demographic.

 

That said the source to the firmware is freely available so if you desperately want to modify the device flash you should be able to modify it to your needs.

 

Also as the netmf runtimes and user code live in the device flash you would be removing resources from the netmf runtime, which frankly is of more use to the ND boards, especially as the plus has an SD card slot and there is nothing stopping you from adding a non volatile form of memory to a shield and writing to that.

 

Nak.
