Set_Bsdl method return error

[PierreCastera]

Hello,

I try to make a boundary scan test bench based on your work but I face a problem with the "set_bsdl" method.

I work on Windows 10, I Install python 3.9.10 32bit and install the setup (py setup.py install). I use a Jlink Base probe for the JTAG communication and I include in my main folder the .DLL file.
I succes the connection with the probe and I can detect the device on the boundary scan chain. But when I want to link the BSDL file I have the error below :

this is my code :

`from jtagbs import jtagbs
from jtagbs.viveris import jtagcore

interface = jtagcore.JTAGCore()
jtag = jtagbs.JTAGBS(interface)

probes = jtag.list_available_probes()
print(probes)

jtag.open_probe('JLINK')
jtag.init_scanchain()

print(jtag.list_devids())
print(jtag.list_devices())

MK64 = jtag.get_device(1)

print(MK64)

#MK64.set_bsdl("./bsdl_files/st/stm32f4/STM32F405_415_407_417_LQFP64.bsd")
MK64.set_bsdl(r"./bsdl_files/nxp/MK/K64_144qfp.bsdl")`

Do you have an idea to solve this issue ?
Thank you

I'll see what happens - you might try replacing the DLL with a more recent version? The "bad parameter" sounds like some sort of error with either the filename or the self.device_id. You might try as a minor test moving the BSDL file into the exact same directory so the path is just K64_144qfp.bsdl in case the relative path is causing an error with the DLL.

I haven't seen that error, I'll give it a try later to see if I can recreate it which would be more useful for debugging (or maybe someone else has?)

Thank you for your quick answer.
The DLL is the most recent version. I already try to put the BSDL file into the same directory but nothing change.
Perhaps the error can come from a bad environement configuration ?
Is there any other action to do for initialize the project in addition to install python 32bit and execute the setup.py ?

hello, test with MK64 = jtag.get_device(0).
