problem upload code from SDCARD

Dear,

I read this github to upload code from SDCARD, i'm little lost: GitHub - zevero/avr_boot: Arduino Bootloader to Flash from SD Card

First, i have 2 boards Arduino Uno, i don't know if you must have the same board?

USB cable is plugged only to Arduino as ISP. D10,D11,D12,D13 is for ISCP. So i cannot uses theses pins on my Arduino code, pins use for this task?

Secondly, i follow : GitHub - zevero/avr_boot at gh-pages

I jump "Manual installation". i have FIRMWARE.bin. I set this file on my sdcard.

I burn Bootloader.

I upload my code from Arduino IDE doesn't take account SDcard, i see the communication between programmer and Target is correct, because i see sound is present from buzzer plugged on Pin 6.

I have this module (on the left):

Wires SDcard module towards Arduino programmer:

CS -- Pin4
MOSI --- Pin D11
MISO --- Pin D12
SCK --- Pin D13
+5V ---- Pin +5V
GND ---- Pin GND

I reset the arduino programmer, it doesn't upload my program.

What is wrong? as if the bootloader has not been applied, or an incorrect parameterization of the SDCARD module

Thank you for your help.

Depends on what you're trying to use them for. Here it seems you use one as a ICSP programmer and the other as the target device (where you want to update code by an SDcard) so any voltage compatible SPI capable device works as the programmer.

USB cable is plugged only to Arduino as ISP. D10,D11,D12,D13 is for ISCP. So i cannot uses theses pins on my Arduino code, pins use for this task?

Hmmh, these pins are used only during programming (on both Arduinos by the way) so depending on what "this task" means, you're right or wrong.

I upload my code from Arduino IDE doesn't take account SDcard, i see the communication between programmer and Target is correct, because i see sound is present from buzzer plugged on Pin 6.

On which Arduino? Don't forget you have two Arduinos, one as a programmer (you must upload software to it to be able to fulfill this job) and one as the target device that must be able to load code from the SD card. To enable that you must change the bootloader (the Arduino standard bootloader allows serial uploads only). For me it's not clear which tasks you already finished and which you forgot.
