STM32L451RC are there Problems known for the BSDL File? I tried to do a Boundary Scan but it is not possible to set the Pins I want. I try to write 334 Bit but If I change the state ob a Pin from outside, I see that this Pin appears 120 Cells before.

That is what I send for exsample:

SIR 9 TDI (0);

SDR 334 TDI (49000000001249240a49249248000000000001249200000000000249249249008000000001249200) SMASK (3fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff) TDO (0) MASK (0);

Hello,

Can you please precise the package you're using?

Package is LQFP64

I Took the BSDL File for the Package STM32L451_LQFP64.bsd and than the Cortex

Hello,

The BSDL chain length is 234 bits long. And it seems that you're shifting 334 bits

Can you check that? an is the STM32 daisy-chained with other devices?

Thank you for your Answer, it is difficult to check without the right BSDL File. I use the File witch is available at the st homepage like specified before, with the zip File en.stm32l4_bsdl. Downloaded a few Weeks before. In the bsdl File the JTAG Interface is specified with 333 Cells (0 till 332). The File is dated with 09-May-2017. Obviously you have an other BSDL File. Can you provide a link to the File? There are no other devices in the scan chain (Except the Cortex TAP).
