Hello Everyone,

I have built a pcb consisting stm32L152V8t6 and other peripherals.I am trying to use JTAG Boundary Scan to test the functionality of the chip. So currently I used the TopJtag(TopJTAG Probe — Boundary-Scan (JTAG) Based Circuit Debugging Software ) ide ,added the bsdl files for stm32L152 with correct MCU_ID_CODE and was able to run following tests:

1. Simple test: read all gpio status while the code is running in background

2.Extest: Control of device outputs and observation of inputs(off chip circuitry test)

I am not am to do Intest:Control of device inputs and observation of outputs(on chip internal logic test).I want to know is it the device which do not support Intest ? or is it the software not supporting intest for the provided bsdl files? I also dint find any application note related to Jtag boundary scan. My aim is to trigger the i/p gpio pins using jtag and check the values of o/p pins. Is this possible?

Waiting for the response,
