Clock glitching on the ICE40

patrick · July 10, 2025, 12:52am

This is somewhat a simple question: is it possible to clock glitch an ICE40 (with the default neorv32 softcore)? That is, is there a project I can build that works similar to the first lab on clock glitching? I tried to run the clock glitching lab FAULT1.1 with the neorv32 target selected, but ran into compile-time errors (not too surprising given it’s a different chip). Regardless, is this possible?

Below is the compile-time error after running:

SCOPETYPE = 'OPENADC'
PLATFORM = 'CW308_NEORV32'
SS_VER = 'SS_VER_2_1'

%run "../../Setup_Scripts/Setup_Generic.ipynb"

%%bash -s "$PLATFORM" "$SS_VER"
cd ../../../firmware/mcu/simpleserial-glitch
make PLATFORM=$1 CRYPTO_TARGET=NONE SS_VER=$2 -j

SS_VER set to SS_VER_2_1
SS_VER set to SS_VER_2_1

It’s definitely possible to try; setting PLATFORM = 'CW308_NEORV32' should be all that you need to change.

Maybe there is an issue with that compiler version; I’m able to compile with this one:
riscv32-unknown-elf-gcc (g1ea978e3066) 12.1.0

So I reinstalled my riscv compiler on both MacOS and inside a Ubuntu VM and got a similar error. I made sure to also tried setting the arch=i_zicsr to include the extension the error printout was complaining about.

I ended up trying to adjust the arch inside the makesife in chipwhisperer/firmware/MCU/neorv32/Makefile.neorv32 by setting “march=rv32i_zicsr” and got a different error (below). It seems this error was caused by an implicit function declaration in syscalls.c inside the neorv32 directory. I added #include “neorv32_uart.h” and this seemed to fix the issue. I think it works now.

In addition to this, when trying the demo glitch loop in lab Fault1.1, got got an error that appears to be related to this post: Husky: No Trigger Seen.
