How to load firmware for SAM3X? #7
Comments
Hello, The SAM3X firmware uses the same firmware loading as ChipWhisperer, so it works in Python (Windows or Linux). The FW update mechanism is described at https://chipwhisperer.readthedocs.io/en/latest/scope-api.html#firmware-update . If the SAM3X is blank, use:
Where is COMx, /dev/ttyUSB, etc depending on platform. You can also force erase the SAM3X with the 'erase' pins (jumper with wire/paperclip). But you can use the ChipWhisperer API to enter bootloader mode automatically too. CW310 is built from running |
Hi Colinoflynn, I see all the power are down in CW310 board, and cannot get the target for ever. |
Hello, This will just erase the SAM3X, does it come back up as a serial port? Are you on Windows or Linux? If on Linux you can check The command from there is:
Where CW310.bin is available here. Just download to your local file. If the serial port isn't coming up, it could be the erase failed. There is an "erase" jumper (pins) on the PCB, you can short with a paperclip/wire which should also force the erase. |

Hi colinoflynn, |
Hello engineers!!
How can I load the firmware on the CW310 board onto the SAM3X on my board? Under what operating system can software be used to load firmware onto the MCU? Is there a method explanation?
