Re: upload code from USBDRIVE to Arduino.

Using Arduino Networking, Protocols, and Devices

Hello,

Can you help me to give me the differents steps to do ?

If i develop a new version of my code, i want to upload this new code on my arduino by SD card or USB key.

That's why i need, the steps and materials to do that.

Thank you.

I offer a card that does programming from SD card.

Other solution with Only 1 board arduino?

Which Arduino board are you using?

I have Arduino Uno and Arduino Nano 3.

OK, you can use the avr_boot bootloader I mentioned previously in this thread:

pert:
If you use an Arduino Ethernet, which has the SD card reader on the board, then you could use an SD bootloader like GitHub - zevero/avr_boot: Arduino Bootloader to Flash from SD Card. That way you just plug in the SD card and turn on the Arduino and it loads the program from the card automatically.

The documentation is not clear, i can use only 1 device Arduino?

What kind of sdcard board must be used?

sdboard

Can be used upload code by USB key via : usbboard
?

Please provide a detailed explanation of what you mean by "1 device Arduino".

lebossejames:

Any common SD module or shield will work.

lebossejames:
sdboard

That will work fine.

No.

No.

I would mean: to flash avr_boot, i need only 1 device arduino.

And after this flash, it can recognize my SD module and can load my code from SD card, if i want to use SD card.

To burn the avr_boot bootloader to your Arduino, you will need an ISP programmer. If you don't own a dedicated programmer, you can use a spare Arduino board as an "Arduino as ISP":

Correct

warning: avr_boot can bootload only from SD card. it doesn't support USB upload

Does exist a bootloader manage SD card and USB key?

avr_boot has this PR
