Hello there,
I’ve been working with the CWNANO device for over a year now. Yesterday I updated the CWNANO firmware to the newest version. Since updating, I am now getting warning messages of an incorrect configuration. For reference, I am using version 5.6.1 of the chipwhisperer library. The following code produces the output given below.
import chipwhisperer as cw
scope = cw.scope()
target = cw.target(
scope, cw.targets.SimpleSerial
) # cw.targets.SimpleSerial can be omitted
scope.default_setup()
%%bash
cd ../hardware/victims/firmware/simpleserial-base/
make PLATFORM=CWNANO CRYPTO_TARGET=NONE
cw.program_target(
scope,
cw.programmers.STM32FProgrammer,
"../hardware/victims/firmware/simpleserial-base/simpleserial-base-CWNANO.hex",
)
The output produced is:
(ChipWhisperer Target WARNING|File programmers.py:413) Serial pins incorrect for NewAE STM32 target
(ChipWhisperer Target WARNING|File programmers.py:414) (tio1, tio2) != ('serial_rx', 'serial_tx')
(ChipWhisperer Target WARNING|File programmers.py:415) Did you forget to call scope.default_setup()?
Detected known STMF32: STM32F03xx4/03xx6

Attempting to program 4727 bytes at 0x8000000

Verified flash OK, 4727 bytes
Please note that the relative pathing assumes that the code is being ran in the /jupyter directory of the chipwhisperer library.
How can I remedy this? Would it be possible to build a previous version of the firmware? Thank you for your time.
