Programming Firmware on target CW303_XMEGA failed

[ben09310]

hello all,

my code:

SCOPETYPE = 'OPENADC' PLATFORM = 'CWLITEXMEGA' SS_VER = 'SS_VER_1_1' %run "../../Setup_Scripts/Setup_Generic.ipynb" %%bash -s "$PLATFORM" "$SS_VER" cd ../../../hardware/victims/firmware/basic-passwdcheck make PLATFORM=$1 CRYPTO_TARGET=NONE SS_VER=$2 fw_path = "chipwhisperer/hardware/victims/firmware/bootloader-aes256/bootloader-aes256-{}.hex".format(PLATFORM) cw.program_target(scope, prog, fw_path)

error:

What's the hardware setup? Is this on a ChipWhisperer-Lite XMEGA board (i.e., ) or something else with an XMEGA attached?

The error OSError: XMEGA Command 20 failed: err=1, timeout=1 is that it didn't find the attached XMEGA device. The "easiest" solution is you're using a different hardware (ChipWhisperer-Lite ARM looks very similar).

However it could also be if you have something on the IO lines interfering with programming, so more details of the physical HW are needed.

yes, i have a ChipWhisperer-Lite XMEGA board. when i change the PLATFORM = 'CWLITEXMEGA' to PLATFORM = 'CWLITEARM' and run the code i get the error code

OSError: Could not detect STM32F, check connections, BOOT MODE entry setup

i'm sure the target board is XMEGA and is conntected, because i get no error code when i run scope = cw.scope()

what details to you need?

i'm a beginner and i want to test the hardware with the program "PA_Intro_1-Firmware_Build_Setup.ipynb" path "chipwhisperer/jupyter/archive"
