Hello,

(how) is it possible to auto-update the program in an MM+ via SD-CARD on site?

It should be possible to detect a program Update on a MM+ via SD-Card.
Idea:
Copy the new program on a sd-card, send it to the site, pluig in the SD-Card, reboot,
the MM+ detects a new version, copy's it automaticaly to program memory (flash) and restarts with tne new program?

Would this be a working solution?
Has anyone another idea?
Proof of concept?

@atmega

If you want to update MM FW you have to erase the PIC chip. So the answer is no
it is impossible to update the FW from SD card yet.

It is possible.
You would first need to load a program in RAM that will read the flash and write those values in flash. Or you reserve a part of the flash for a bootloader.:)
Which is already done many times. Most of them use the USB as a means to get the data to be programmed into flash. The data could just as well come from an sd card.
Microblocks. Build with logic.

@ Boss

I Never talked about a Firmware (Mmbasic) Update,
The Question is about updating the programm running in the Mite, from sdcard.
Has anyone a detailed description for a working procedure?

That is easy, just use:
LOAD file, R

The ,R suffix causes the program to be run immediately after it has been loaded.

I think Boss was reading the Title of your thread which clearly mentions Firmware!
