How to use BSDL Files :
=======================

The STM32U5 MCUs integrate two serially connected JTAG TAPs, the boundary scan
TAP (IR is 5-bit wide) and the CortexMx TAP (IR is 4-bit wide).

The package contains :

   + A BSDL File for the CortexMx TAP and is common to all STM32U5 devices
   + Boundary scan BSDL Files for each STM32U575_585 devices on different packages :
          
	  o LQFP48
	  o LQFP64
	  o LQFP100
	  o LQFP144
	  o UFBGA132
	  o UFBGA169
	  o UFQFPN48

   + Boundary scan BSDL Files for each STM32U575_585_SMPS devices on different packages :
          
	  o LQFP48
	  o LQFP64
	  o LQFP100
	  o LQFP144
	  o UFBGA132
	  o UFBGA169
	  o UFQFPN48
	  o WLCSP90

   + Boundary scan BSDL Files for each STM32U535_545 devices on different packages :
         
	  o LQFP100
	  o UFBGA100
          o UFBGA64
          o LQFP64
          o LQFP48/UFQFPN48

   + Boundary scan BSDL Files for each STM32U535_545_SMPS devices on different packages :

          o LQFP100
          o UFBGA100
          o WLCSP72
          o UFBGA64
          o LQFP64
          o WLCSP56
          o LQFP48/UFQFPN48

 + Boundary scan BSDL Files for each STM32U595_U599_5A5_5A9 devices on different packages :
         
	  o TFBGA169
	  o LQFP144
          o UFBGA132
          o LQFP100
          o LQFP64

   + Boundary scan BSDL Files for each STM32U595_U599_5A5_5A9_SMPS devices on different packages :

          o TFBGA216_DSI
          o WLCSP208_DSI
          o TFBGA169
          o WLCSP150_DSI
          o WLCSP150
          o LQFP144
          o UFBGA132
          o LQFP100
          o LQFP64

   + Boundary scan BSDL Files for each STM32U5F7_5G7 device on different packages :
  
	  o LQFP100

   + Boundary scan BSDL Files for each STM32U5F7_5G7_SMPS device on different packages :

	  o LQFP100

   + Boundary scan BSDL Files for each STM32U5F9_5G9_DSI_SMPS device on different packages :

	  o TFBGA216
	  o WLCSP208
	  o LQFP144
	  o UFBGA144
	  o LQFP100
	  
       
	

In order to run boundary scan, always provide two BSDL files to your JTAG Boundary scan tool:
the "CortexMx.bsd" and your selected "STM32xx_device_Package.bsd".  

WARNING : Do not combine both BSDL files in a single TAP with 9-bit wide !

For more details on the internal TAPs description refer to the Reference Manual
of the selected STM32xxxx device , Section : JTAG TAP connection.
